Never again fumble with True Ark pliers trying to remove a clip holding in the Stripper. With C.E.’s Side load you simply lift punch out and slide stripper out.

• More Support C.E. Guides have more bearing surface between the punch and guide. This additional support we have added in the spring cage extends superior tool rigidity.

• High Wear Guides Haredend to Rc 38-44 + Surface Treatment to extend extended guide life, yet stays within the maximum supported hardness recommended by machine builders such as Amada & Strippit® . Use of guides harder than this can cause pre-mature wear to turret casting or bushings.

C.E. PRODUCT FEATURES HIGHLIGHTS

EXCLUSIVELY From C.E. TOOLING The QUICK-SET™ Tool Holder System

This patented tool length adjustment unit allows for fast, simple tool holder set up for standard and special application tools.

Form tool holders adjust in as close as .0025” with only a lift and turn of the outer knurled collar. Standard Tool Holders adjust in .006” ,15mm

increments with a push of a button located in the side of the lifter flange. Tool length can’t change during use. re-duced set up and maintenance costs.

DIE FEATURES Constant Clearance in Corners Superior part quality: Prevents large corner burrs, makes dies stronger, increases die life. Strongest Dies: To allow the slug to fall through die, often die-back must be relieved. CE burns a 3° taper to allow slug to pass though with little drag. On corners of shapes such as rectangles, rather than leave sharp were they can attract stress and create a crack line, CE takes the care to burn a tapered radius relief. This is an important feature skipped by most of our competitors.

In order to receive optimum performance from a punch and die, it is necessary that the proper clearance be provided in

the die in accordance with the material to be punched (pierced). Hole quality (edge roll, and burr), tool life, and slug

pulling are results from die clearance. •Excessive clearance, although achieves longer tool life, will

leave more burr, and leads to slug pulling problems. • Insufficient clearance will leave little to no burr, but lessen tool life, and can cause a secondary break . Note: Increasing die clearance when holes are close to edge of sheet will minimize distortion of sheet edge.

PUNCH TIP COATINGS TiN Titanium Nitride • TiCN Titanium Carbon Nitride

Gold Colored Bluer-Grey in Color The increased tool life from using coatings varies. Primarily coatings extend lubricity to the sides of the punch, reducing galling. Further, coating extend a harder surface which extends hits between sharpening. Extended life will be directly related to the rigidity and alignment of the press, and the material type and thickness being punched. On a rigid press, punching 16gage mild steel, we believe TiN (Gold) may extend 3-6 times more hits before the first sharpening. TiCN (Grey) may extend 5-10 times more hits before the first sharpening. After the first sharpening, the extended life between sharpening probably cuts in half. The argument against coatings, is that their may be better value in simply utilize punches with higher quality substrates like High Speed Steel, and place more attention to continues lubrication to the moving components of the tool. A High Speed Punch will general, outperform, say a D2, A2 or A8 punch coated with TiN(gold), at a much lesser tool

cost. On the other hand, although having an initial higher cost, the TiCN coated D2,A2 or A8 punch in ideal conditions may out perform the un-coated High Speed Steel tool.

CE’s opinion, monies are best spent on upgrades to High Speed Steel. Then if

further edge life is desired, consider coatings. Which coatings to use? TiN is good in applications punching

soft material like aluminum, as your concern here will be the adhering(galling) of the material to the sides of

the tool placing wear on punch tip and greatly increases required stripping force. TiCN seems best suited for harder materials, as it is a harder coating and adheres (meshes) to the steel better than TiN. Their is less tendency for this TiCN to chip or flake.

Dies Types: To allow the slug to fall through die land, a taper relief is given to allow slug to pass though with little drag.

Slug Pulling:Techniques and Tool Options Slug Pulling is when the material that is suppose to drop out of the die instead sticks to the face of the punch and pulls up out of the die. This slug can then drop on top of the sheet. If a punch has the misfortune of striking this slug on a future hit, two types of damage to the punch can occur. If the punch hits squarely on the pulled slug, it may merely cause the punch to have to pierce through two material thickness into a die with clearance meant for only one material thickness. The result is

heavy edge wear and gauling. The more damaging occurrence is when only a portion of the face of the punch hits the pulled slug. This can cause side load pressure in which the punch may shear (scrape) against the dies great wear or edge roll to punch and dies cutting edge.

Common Causes of Slug Pulling Suggested Solutions

Excessive Die Clearance Check the die clearance (reference page 4). To large of clearance, although increases punch life, can greatly increase the likelihood of slug pulling.

Slug is attaching itself to Punch Face. If punch is equipped, add Slug Ejectors.

Punch Face is Magnetized, attracting Slugs. Have Tools Demagnetized

Lubricant on light gage material causes suction between the punch face

& slug.

Remove lubricant on the top of material. lubricate the bottom of sheet instead. Add Shear (Inverted, Roof Top or Spherical) to punch. This will kink the slug preventing it from suctioning to face of punch.

Try Slug Trap™ or Slug Hugger™ die. (See Page 6)

Add Shear (Inverted, Roof Top, or Spherical) to punch. This will kink the slug, making the shape hug tightly to the sides of the die wall(refer to page 7). Using a sharp edge of a diamond file, add some notches to the edge of the die wall. (.02-.03 deep, & 30-40º to the die land.) No burr will be left in the hole of the sheet but it will cause a slight burr to the slug that will help grab onto the die land.

Punch is not Penetrating a Proper Depth into the Die

Reference page 12 for minimum suggested tool sharpening lengths.

Slug not Adhering to Die Land

Reduce galling, increase tool edge life, and improve stripping. Use with standard tools, forming and cluster (gang) punching. To use, simply spray or wipe this premixed lubricant on every 3-6 sheets placed in press. CLM-50 Formula is a oil base, so may be mixed with kerosene to conserve, or for easier sheet cleaning when plating is to be performed. This is best lube for reducing galling on sides of tools, and extending edge life. If your trying to keep away from oil base, our Poly-Form™ is a water base, soluble polymer lubricant for CNC turret and high-speed punch presses. It’s an excellent lubricant for soft nonferrous metals, such as aluminum, copper and brass, and will protect your nonferrous metals from oxidation, including galvanized and tin-plate. Clean to work with and doesn’t stain skin or clothing or cause dermatitis.

COLE ENGINEERED To Nibble means to take repeated bites (to not punch with all edges of a punch). Edge life on tools used for nibbling will wear more quickly than tools used for piercing. This due to the tendency of a punch used for nibbling to side load which can cause the punch to shear against the die’s cutting edge. When you pierce a hole, the punch tip follows into the center of the mating die as it takes the

easiest path to pierce through the sheet. When you nibble, the punch can float side ways to an extent allowed by play inherent of all turret punch presses. Explanation :The 1st 25% of penetration of punch tip into a sheet merely stretches the material(no cutting). This is the section of the stroke were much of the side pressure onto the punch tip comes from as the path of least resistance is sought. (Ex. a .200X1” punch taking a bite (suggest 75% of punch surface) which cuts on only 3 sides will be pushed sideways towards the edge of punch which is not cutting.) The next roughly 35% penetration does in fact cut(shear), but if side pressure has started, the side of punch not cutting, may continue it’s side pressure causing the punch to shear on the cutting edge of the die. The remaining 40% penetration through the sheet actually tears. (These percentages are rough estimates as material type and clearance plays an important factor.)

Depending on your companies specific requirements and fabrication goals, their are techniques and tool options to extend greater tool life when nibbling.

Read through the below and keep in mind their will often be a pro and a con to each option or technique. Standard punches and dies (ref. page 4 for clearances) can be used for nibbling and extend good edge life. Best for punch width to be 2-1/2 times material thickness. Guided punches were tip is supported by close clearance metal stripper plate will extend life.

1st and most important, carefully program hits to prevent tools from side loading! Program bridge hits, or take nibble bites of no less than 75% of punch area. Not following these rules even for 1 or 2 hits, can cause side load pressure to the punch in which the cutting edge may make contact with die causing instant edge break down!

2nd Punches can be ordered with Inverted Shears(1/32-1/8 deep depending on tooling style). A shear on a punch does a few things. We initially suggest inverted shears for nibbling as the heel on the punch centers the tool when

performing a Bridge hit, and when taking a nibble bite with only a portion of the punch face, the rectangle pad on the side of the punch shear imbeds itself into the material helping to prevent the punch from side loading and shearing on the die. Another feature of the shear is to reduce the tonnage required (reference page 6). Lastly, the shear on the punch helps prevent slug pulling. A shear prevents the slug from suctioning on the face of a punch. This a result created when a flat faced punch presses tightly against the sheet, squeezing all the air out between itself, and the pending slug. Further, the slug is

kinked from the punch shear, making the slugs shape hug tightly to the sides of the die land.

3rd For nibbling, extend die clearance by up to 50%. Example, if our chart on Page 4 calls out .008, move up to .012 clearance. This extra clearance allows more room for the punch to flex side ways before it can shear on the side of the die. The negative to increasing the die clearance, is it opens up more possibilities to slug pulling. Tighter clearances extends reduces slug pulling and higher hole quality. Opening up clearances, greatly extend tool edge life, but can cause slug pulling problems, and larger hole burr.

4th Punches can be ordered with heels. A Heel on a punch will extend past the standard length of punch by 3/16-1/4”. The heel enters into the die prior to punching which prevent punch tip, extending ridged support and alignment. (Prevents punch from shearing on to die edge.)

Tool Edge Life: There are many factors which determine the actual useable life of a punch & die between sharpening. Such factors are and not inclusive of rigidity of press,

condition of turret, wear tolerances of holders and variations of material thickness and type (stainless, aluminum, mild steel, etc...)

Tool Cleaning and Lubrication should be part of any maintenance program. Regardless of what type of oiling system or grease you use, it is important to visually inspect the tooling from time to time. Certain materials, such as hot roll or galvanized steel, have a tendency to flake or scale. This foreign matter can work its way into the guide assembly and have a galling effect causing the tools to seize up inside the guide assembly or turret bore. Fully disassemble the tools wiping out all old oils or greases. It is not recommended to use: 1)Sulfur-based grease/acid-based lubricants, 2)Lightweight oils or 3)An air hose to clean turret or tool as particles of dirt can contaminate and possibly lodge slivers in die bases or turret bores.

Limit Tool and Turret Wear: Lubricate wear surfaces of punch, guide, and turret by applying a quality bearing grease such as “ADS-71 Extreme Pressure Grease” . Other choices are graphite or molly based grease or a light coat of machine oil such as a 20-30 weight oil. Some tool systems like CE’s SL™ and competitors S80 holders allow 80-90wt oil to seap from a built in resevoir. Further, tooling systems like CE’s LS™ and competitors 90abs, S90wls and Ultra units are designed for machines equiped with ABS (Air Blow System) or ATL (Automatic Tool Lubrication) lubrication on every cycle of press.

Tool Sharpening: The actual physical process of grinding (sharpening) can greatly effect the tools continued performance! Improper tool sharpening can cause premature tool edge failure. If you heat up the tool, you may be annealing the steel, bringing down its hardness thus causing lower wear resistance. Further, if the steel discolors during a grinding pass, even if on a following pass, these burn marks can be hidden. The stee’ls surface may later form surface cracks (buckling of the outer most skin surface). If facilities aren’t available to properly care for your tooling, CE offers a tool sharpening service.

Sharpen tools when edge shows .010-.015 of break down. Punches often require sharpening 2-3 times more often than dies. If the tools are not sharpened at proper intervals, edge breakdown becomes more rapid, hole quality deteriorates and a tool will require much more metal removal to achieve a sharp edge. The result is reduced tool life.

Grinding Wheel Selection: Use an open coarse wheel such as a 46-60 grit, H-J hardness. CE sells common surface grinder wheels: 7-8” diameter. 1¼ID X ½” Width 46H grade. Call for current pricing!

Dressing of Grinding Wheel: Move diamond across wheel at a fast steady pass of (4 IPM). Take multiple passes at depths of .001-.002”. A good way to think of dressing is that your using the diamond to rip out the dull stone particles to expose fresh jagged edged stones.

Grinding Tool: Take frequent light passes of no more than .0005 to .001 inch. Removal of more than this may cause the tool steel to burn resulting in the edge becoming brittle and chipping on the edges or corners. Keep Constant Flood Coolant on tool to prevent steel from heating up. Removal of .005 to .010” should return the tool to the proper sharpness. By hand, rub a medium oil/india stone on newly harpened edges to reduce strengthen and reduce edge wear during punching. Lastly, Demagnetize tools to prevent punched slugs and slivers from adhering to them.

Punch and Die Shimming: The reason for shimming is to compensate for the material that has been removed by sharpening, thus maintaining overall penetration depth which helps prevent slug pulling. To determine the thickness of shim to be added, measure the sharpened tools length and subtract the difference to that of a new tool height (ref. chart on the following page). On self-stripping style guide assemblies, this usually just means adjusting the punch tip to sit 1/32-1/16 below a stripper face. To add a shim in a punch holder usually means disassembly of

the punch from its holder, insert the shim, then re-assemble the punch. Some new style tooling can be adjusted with out use of shims. Don’t over shim tools or damage to holder may result. Assure that punch tip length (straight before radius) is adequate to penetrate through the metal stripper plate (if used), the thickness of material to be punched and enter into the die 1/8-3/16”.

With most tool style, Grind Life of Punches often has little to do with their overall length. Length adjustment can often be easily adjusted in the tool holder or by machine stroke control. In most cases, what determines the usable life of a punch is its ability to pass through its stripper & material it is to pierce along with and penetration into die. A punches SBR or “Straight Before Radius” is the real measure of life. SBR is determined by CE by taking in account the unique strengths of tool style, rigidly of the press and range of material thickness tool may be used for. A simple method of determining when a punch is no longer usable is for the us-er to: Find distance a punch tip penetrates through stripper, subtract material thickness that will be punched then subtract the penetration into die.

Suggestions for Longer Life Between Sharpening Tool Alignment ● Maximum die clearance without causing to great of burrs or slug pulling Sheet Lubrication. (WD40 may stop slug pulling and keep equipment from rusting but does little to reduce cut edge wear). It is easy to believe that if you get few thousand more hits with a tool you will get more value. When tool cutting edges show .010” radius, they need to be sharpened. If this is not done, tool edge wear will increase rapidly requiring a great-er amount to be sharpened off the tool, thus reducing overall life.

Punch Tip Breakage: There are two common causes of tip breakage. 1st when a slug is pulled up onto top of sheet, and the small punch tip hits on top of it. The punch tip hits this slug left on the sheet, causing more side load pressure to the tip than what it can withstand. Solutions to slug pulling page 8. 2nd material build up(gauling) on the sides of the punch tip. The material being punched grabs on more tightly to the galling on the punch tip adding much stress as it strips. Breakage may eventually occur during the upward stripping motion. Solutions Lesson gualing build up by clean off any material that builds up(galling) on the sides of the punch tip before it becomes excessive. Further to lesson gualing, order punches with extra back taper. (Punches come standard with 1/8º, ask for 1/2º, No Extra Cost. Also, TiCn (Gold) coating is best for pre-venting gualing. Last, use a sheet lubricant that can reduce gauling build up. (See page 8).

Properties of Tool Steels Wear Resistance • Red Hardness •

Toughness All properties are important in achieving a steel that will stand up to various punching conditions and materials. for punches, wear resistance and steel toughness are most relevant. Wear resistance stands out to be the most dramatic property which effects the life of the punch. In achieving high wear resistance in most cases steel toughness diminishes. With out this toughness, steels tend to flake more easily in adverse conditions causing dramatic tool breakdown. Red hardness is most important to the punch. This is the measurement of temperature in which the punch can be taken to in such applications as nibbling where heat from friction plays am important part of tool break down. Further, as often tools are softened by improper sharpening, the greater the Red hardness, the grater abuse the steel can withstand during grinding. For dies, steel toughness is by for the most essential property which effects the tools performance.

Shear

A shear on a punch does a few things. We initially suggest inverted shears for nibbling as the heel on the punch centers the tool when performing a Bridge hit, and when taking a nibble bite with only a portion of the punch face, the rectangle pad on the side of the punch shear imbeds itself into the material helping to prevent the punch from side loading and shearing on the die. Another feature of the shear is to

SET UP INSTRUCTIONS: 1. Inspect the material thickness to be punched. To prevent poor form quality or damage to the form tool,

only use a tool for the sheet thickness which the tool was designed for. If critical to the tools design, “Mat-(material thickness)” will be engraved on tool. If only a clearance is etched, tool most probably can be used for a range of thickness and has no positive stop.

2. Prepare upper punch unit to be loaded into turret. Set the overall length of tool to the SHUT HEIGHT of Press -minus Sheet Thickness. (unless your certain of machines shut height it is safe to subtract an extra .04/1mm in length.

Forms requiring large movement will move sheet below standard die height. For this, no dies should be in stations to left & right of form dies. Ideally Lifter dies should be installed either side of form. See Page 19

3. Load Die into turret making sure it is aligned to punch. Don’t place shims under die unless their is a notation engraved requesting shims etched on die. .

4. Perform a single stroke of the press and check the results. Increase tools length accordingly. Don’t over adjust length! Better to move small increments to prevent bottoming out tools. Repeat this step until desired form height is achieved.

Note: Never attempt to exceed the forming height which the tool was designed for. If critical to the tools design, “F.H.=(form height)”,for which the tool was designed to perform under is etched on the tool.

PROGRAMMING SUGGESTIONS • Form tools should be the last operation punched.

• As a form die is higher than a standard die. On deep stroke forms, no die should try not to program the use of either station adjacent to the form.

• When available, always program reduced striker speed, and + pause or dwell after each hit from a form tool. Metal stretches best at slower speeds. Pauses & Dwells gives extra time for the sheet to be stripped off tool.

• For Progressive Tools, see page 22 & 24

TOOL MAINTENANCE •CE Tooling offers sharpening/re-conditioning of form tools at very reasonable rates and turn around of usually 1-2 day turn around. Unless user has full understanding of form tools design. Common regular maintenance of a form tool is simply to clean and rub off any gualing build up. Insist that operators use a sheet lubricant such as CLM50 (page __) to help lessen galling and improve cutting edge life. If there is a cutting edge, study tool, and determine the different heights of tool which must be maintained. Example, when sharpening an electrical knock out style form, equal amounts must be sharpened off cutting edge as positive stop (ejector ring) .

If you have any questions about maintaining/sharpening a particular cutting edge of a form, call our engineering department (702) 736-2958 or [email protected] for guidance. All specials have a S-#### etched on the tools. Giving this number to our tool engineers ill allow them to retrieve detailed information about your tool.

FORM REQUIRING LARGE STROKE (Deep Stroke) Diagram shows sheet movement below standard die height.

Form requiring deep stroke will require sheet to be moved below standard die height. No dies should be left installed in stations to left & right of such form dies. Ideally lifter dies should be installed either side of form.

Lifter dies are placed in your turret on each side of a special forming tool. When the sheet passes through this section of

the turret, these lifter dies will lift the sheet up above that of a standard die. This will help guide sheet to the height of a tall forming die preventing an abrupt jerking action when sheet meets form die which at times causes the sheet to break the grip of the work holder clamps.

A pre-pierce hole is commonly required as a one hit pierce and extrude gives poor hole quality, and has limited adjustment on the machine. The diameter of the pre-punched hole ultimately determines the height of the extrusion. Max. height (H) is the metal’s limit of being drawn (stretched), and form dies max. height above + .1” below standard die.

If distorting, apply forming lubrication like CLM50 (page 8 ) this will help material slide over tool surfaces better, allowing a more even bend and stretching and reduce galling & distortion in formed wall.

If a Single Hit Pierced and Form is Chosen, be advised that the hole quality and tool life will be greatly reduced. Reason: The metal being coined has no were to go but to bulge on the top of sheet (roll over), against the pilot tip and pushes below the sheet leaving a large burr. This binding of the pilot tip by the material causes rapid galling which if not constantly cleaned off can cause the pilot tip to be snapped off during the stripping cycle of the stroke.

COINING Pre-Pierce hole hole is required. Lets call material thickness “A” Best quality: use “A”= only 90% of mat. thickness. 1st Step is to determine if material thickness “A”=material can accommodate screws

“H” head height with sheet staying flat. If “A” is > “H”, “C” can= Screw thread size

PrePierce=((B-C) / 2)+C) Formula estimate larger for safety. After tests, pre-pierce size may be reduced to achieve best cosmetic results on your material type. Note: To small a pre-punch hole causes material to coined tightly around the pilot of the form insert. The result can be problems with stripping, heavy burrs, bulging of material, and excessive tool gauling.

If “A” < “H” you will have to choose between having a larger “C” thru hole size were material can be kept flat shown in fig. D (screw will be centered on head and not thread) PrePierce=((B-C) / 2)+C) Must use Die Size=B-(((D=Angle/2)TAN X A) X 2)

Else you will need to allow the material to be bent shown in fig. E Use a die that has an opening => B+(1.2 X Mat. ) die edges not sharp to help lift of material.

Nibble range=.025-.75” See Page 24. Expect a small blemish were nibbling starts. Progressive tools are made to exact material thickness, were standard louvers can punch a range of material thickness. Progressive louver must have gentle radius slope on end, were standard louver can be tight radius.

FORM DOWN TOOLS: Generally used in single station manual or duplicator presses, due to problems with formed tab catching on table or tooling as sheet is dragged into further positions for unloading or punching. There are cases were form down operations are performed in turrets. Desire to not flip sheet over, or possi-bly due to often ability to form greater height.

Contact our tooling engineers to discuss your particular application. Camera Ready Art Work or .DXF/.IGES files are required for Logo’s. Go to the dedicated pricing booklet (Section 2-9) for the tooling style used in your machines for information of station capacities, character quantities and pricing.

Tool Overview: Use and Set Up

Character Marking Units are classified as a form tool. Unlike a standard piercing punch which punches through the sheet metal and into a mating die, a form tool has to be set to a near exact length to allow the punch to firmly spank the top of the material which lays on top of the bottom die. If the punch length is adjusted to long, the press will drive the punch into the bottom die resulting in probable damage to the tooling and possibly to the machine. Unless specifically requested and marked on the tool, marking tools are designed to be used in a maximum material thickness of 9 gage (.150” or 3.8mm) if the tool is to be used to punch thicker material, steps must be taken to reduce the length of the upper unit.

The first step in setting up any form tool is to adjust the tool to the Shut Height for the exact Machine which tool is to be used on - (minus) Materials thickness. (C.E. offers tools used to check machines shut height). After the tools length is set, load tool into the press, making a single hit, checking the results. Next make SMALL adjustments to the tool’s length to set proper penetration. (Usually only .004-.008 on coin style marking tool (sharp faced engraved characters,logo’s, or shapes) The life of the tool will be greatly affected by the depth the tool has to stamp into the material. Although sharp faced replacement character, or a engraved logo, or shape, are produced with approximately 1/32 depth of useful detail, it is recommended to penetrate into the material only .004 to .008 for maximum tool life. If you are punching in C.R.S. this depth will normally give about 10,000 to 12,000 hits before showing signs of break down. An example of how the life of the tool will be affected by the stamping depth: if you were to penetrate .012 to .015 depth in C.R.S. expect approximate 7,000 hits before signs of break down. How much longer the tooling can be used would be at the discretion of the set up person to determine if the quality of the detail is acceptable. Logo and solid type sharp face tools can be sent back to C.E. Tooling to be sharpened. This style of tooling can be made either form-up or form-down style. There are 2 DIFFERENT TYPES of character marking tools. Shown on this page are the popular COIN STYLE marking stamps. A Coin style marking unit has sharp face characters that are pressed very shallow into the one side of the material while a the opposite side of sheet is pressed against a flat no hole die (flat faced punch if forming up), which act’s as an anvil to support the material. The other type of character marketing tool is the “EMBOSSING STYLE” stamp. Just like the sharp face style, the length of the punch is very critical. This style tooling is pressed on the side of the material and embossed out the other side, the cost of this tooling is greater due to the detail had to be on both the punch and die. Most generally the tooling has to be made as form-up. Use CLM50 Sheet Spray to extend edge life. (Ref. Page 8)

WHEN CHANGING THE QUICK-SET HEAD OR PUNCH BODY WE RECOMMEND SENDING YOUR PARTSBACK TO C.E. TOOLING AND WE WILL MAKE THE CHANGE AT NO CHARGE. HOWEVER, IF YOU WOULDRATHER MAKE THE CHANGE HERE ARE TWO WAYS TO MATE PARTS TOGETHER. FIRST, REMOVE SETSET SCREW IN THE SIDE OF THE GUIDE BODY AND UNSCREW QUICK-SET HEAD FROM GUIDE BODY AND REMOVE INTERNAL PARTS. SCREW NEW QUICK-SET HEAD OR NEW GUIDE BODY TOGETHER.IF REPLACING THE GUIDE BODY SEE IF THE 1/4-20 THREADED HOLE MATCHES UP WITH THE HOLE IN THE SIDE OF THE QUICK-SET HEAD (it probably won't). IF IT DOES UNSCREW QUICK-SET HEAD AND INSTALL INTERNAL PARTS IN ORDER AS THEY WERE REMOVED, SCREW QUICK-SET HEAD ON AND INSTALL 1/4-20 SET SCREW. BE SURE SET SCREW SITS BELOW GUIDE BODY DIAMETER.IF HOLES DO NOT MATCH UP UNSCREW QUICK-SET HEAD UP TO 1/2 TURN TO SEE IF HOLES WILL LINE UP.

IF 1-4-20 HOLE DOES NOT LINE UP OR YOU ARE INSTALLING A NEW QUICK-SET HEAD YOU WILL NEED A 13/64" DRILL BIT AND A 1/4-20 BOTTOM TAP TO COMPLETE THE FOLLOWING.WITH THE INTERNAL PARTS REMOVED AND THE QUICK-SET HEAD AND GUIDE BODY SCREWED TOGETHER, DRILL THROUGH THE OVERSIZED 1/4-20 THREADED HOLE OF THE HARDENED GUIDE BODYINTO THE THREADS OF THE QUICK-SET HEAD 3/8 MAXIMUM DEPTH.

CLUSTER / GANG PUNCHING

MAINTENANCE: Use sheet lubricants (ref. Page 8) Keep punch quills as sharp or sharper than the die.

SHARPENING: Small quills while still assembled in punch body. Put wax between quills and attach strong rubber bands around pattern to lessen vibration and prevent quill breakage.

Disassembly: Remove the bolts on location plate and carefully pull location plate off of punch body. Clean off any galling around tip to prevent jamming. Quills should be tapped out of location plate using a piece of brass or aluminum. Carefully clean location plate before installing new or sharpened quills. After new or sharpened quills are tapped back into location plate, you must surface grind back of quills and plate until level to each other. Do this by laying location plate between two magnetic parallels & set on a surface grinder magnet. Place location plate back on punch base being careful to realign dowel holes as marked. Tighten bolts securely using a none permanent type of thread lock, such as Loc-Tite. Prevent sheet warping & reduced die edge life: If hole patterns are to close, remaining web thickness becomes week and will cause sheet warping. To prevent this, double space to punch every other hole, then come back and punch between holes already punched .

Programming: Plan your hits so that none of the quills of a cluster tool re-enter a hole previously punched. Clusters are prone to sheet deformation so they are not warranted against this. How much depends on closeness and shape of holes. To lessen deformation, use CLM Sheet Lubricant and program press to punch the Outside of grid pattern and work in towards the middle.

Cluster Tools reduce hits required but most importantly reduce sheet warpage, common problem of multiple single hits in close proximity.

Reduce material warping. Use CLM Sheet Lubricant. Each time a hole is pierced, material surrounding the hole is stretched downward placing stress on the top of the sheet. The more holes pierced close together, the more chance of the sheet warping. Prevent this by punching every other hole , and then come back and punch the remaining holes . An even greater solution is flip part over to punch holes.
