Holz-Her ECO-Master 7120- M CNC MACHINING CENTER

Holz-Her U.S. Inc., the industry leader in product quality and customer support, is proud to present the latest in CNC machining technology: the Holz-Her ECO-Master 7120-M CNC Machining Center.

The Holz-Her ECO-Master 7120-M represents the most advanced CNC technology and the best service and support programs in the woodworking industry. Base Design The ECO-Master 7120-M is a heavy-duty machining center that is capable of handling the toughest routing and shaping requirements as well as the fast and precise drilling requirements of the most demanding wood shops. This is due to the basic design of the ECO-Master which incorporates a heavy-duty frame construction with the proven solid arm stationary “Y” axis support arm design.

Both the machine base and support arm are manufactured from heavy gauge steel, normalized after welding. The normalizing process will relieve any stress in the metal prior to further machining operations insuring very accurate drilling for guide way placement. This design also requires much less floor space behind the machine in comparison to other designs. The heavy-duty frame and the rigid arm design provide for vibration free machining as well as for full support of the head movement through out the entire machining cycle. This is most

important at the outermost points of the machining cycle. When the machining center is machining at the front of the work envelope the rigid arm design provides full support of the working units while also minimizing the unsupported overhung load.

Bearing Guides and Ball Screws

The Holz-Her ECO-Master 7120 utilizes the latest in linear motion technology.

Bosch-Rexroth high precision guide ways are used on all three axes X, Y, and Z along with the vertical movements of the router motors. Bosch-Rexroth brand guide ways are designed to provide the utmost accuracy and repeatability while minimizing vibration when moving heavy masses at high rates of speed.

The preloaded bearings are four row circulating type bearings for maximum speed and life. The high precision bearings also have double lip grease and dust seals providing years of service. Fast & Precise positioning in the X-axis by means of Rack-and-Pinion drive system.

Matched sets Bosch-Rexroth brand ball screws and nuts control the movement of the Y and Z-axis.

Y-Axis Ball Screw Diameter – 20 mm

Z-Axis Ball Screw Diameter – 25 mm X Axis Speed 75 meters/ 2953 inches per minute

The diameters of the ball screws on the Holz-Her ECO-Master 7120-M are unequaled by any

other machine in its class. All high quality machinery builders regardless of their industry recognize precision ground and hardened ball screws with matched nuts as the premier system for positioning machine positioning. The screw and nut are a matched set eliminating any potential for backlash problems, this allows for reliable part machining and repeatability over the life of the equipment.

Servo Motors

The movement of the head is controlled along all three axes by heavy-duty brushless drive motors, driven by a matched digital driver. Solid State electronics will produce a more constant output of torque resulting in faster speed with more reliability.

Work Envelope

The work envelope of approximately 3,268mm x 1,479mm (129”x 59”) allows the utmost in machine flexibility and part application. The vertical stroke of 320mm (12.6”) gives the Holz-Her Eco-Master 7120-M customer maximum flexibility for machining large parts.

Displacement Travel: X-axis Length 3268 mm (129.’’) Y-axis Width 1479 mm ( 58.9.”)

Boring Pattern Dimensions: X-axis Maximum 3189 mm (125.55”) Y-axis Maximum (all drills) 1185 mm ( 47.4”) Y-axis Maximum (single drill) 1217 mm ( 47.9”)

Router Working Dimensions: X-axis Maximum 2993mm (118.”) Y-axis Maximum 1456 mm ( 57.32”)

The boring head is provided with a 12 HP (9 kW) liquid-cooled electro-spindle and

utilizes an HSK-63F tool connection; four ceramic ball bearing assemblies are also used to dissipate thermal growth from heat. The electro-spindle is a 1,000-24,000 RPM variable speed motor, left hand or right hand rotation controlled by the computer.

Each individual spindle has three bearings and is pneumatically actuated. The bearings are located so that the spindle is supported by one bearing at the bottom and two at the top. This insures precise vertical movement as well as optimum hole quality even toward the end of recommended tooling life.

The boring head also comes with a 2 HP (1.5 kW) X/Y-axis grooving saw head that rotates a 150 mm diameter saw blade at 4,850 rpm. Saw blade not included

This allows the customer the option of grooving panels without using one of the aggregate spaces for optional heads.

NOTE: Optional horizontal spindle is shown

in above photo

The HSK F63 Cone Tool Holders included as standard allow the customer the option of

changing the tools quickly by hand with the push of a button or allowing the tool change to occur during the machining cycle automatically via the program.

The Holz-Her ECO-Master 7120 standard boring head configuration is a 14 vertical independent spindle-boring block, 10 in the X-axis and 4 in the Y-axis that also includes 2 horizontal spindles in the X-axis as well as 2 in the Y-axis.

The twelve (12) position tool changer moves in the X-axis, riding along with the rigid arm, in

combination with the 12 HP (9 kW) electro-spindle. The twelve (12) position rotating type tool changer with HSK shank connector allows the Eco-

Master machining center to shorten typical cycle time as well as allowing the operator to continue to load and unload the idle work zone without interference from the tool change. This feature eliminates the requirement of having to shut down the idle work zone during a tool change. A wide range of tool changers are available as an option to meet your specific tool changer needs.

The Work Zones and Vacuum System is divided into two independent working zones each available

with 3 optional pneumatically controlled pin stops located on the front of the machine.

The working table is manufactured from High Density Phenolic and is segmented to

allow the table to be divided according to the part sizes and shapes being machined. The table can also be divided into two sectors to allow for the working of one zone or the other alternately. 2 sets of 4 pop-up pin stops are provided in both the right and left rear zones for panel positioning. Front zone pins stops are available as a factory ordered option and must be ordered at the time of production. 60, 90 and120 mm diameter vacuum cups for horizontal drilling are available as an option.

The hold down is achieved via (2) Becker Duplex Oil-Less 250m3/hr vacuum pump rack system (2-10Hp 250 c/m vacuum pumps) operated by the CNC controller. This system can achieve flow of 350 CFM. Becker Pumps maintains a Service center in Akron, OH.

The system is also offered with a Sound Reduction Cabinet with heat ventilation fans as standard with the Holz-Her ECO-Master 7120.

Safety Equipment provided as standard Safety foot mats in working area Safety Casing in accordance with CE Regulations Side and rear mesh-grid frames, including safety door Hand held control unit Automatic lubrication system for all axis and Guideways Cooling fan for electrical cabinet

The Hard Drive is 20 GB with 128MB of SDRAM (1 DIMM), 256KB Cache Memory, 8MB Video Memory along with Networking Capabilities.

The PC-based, Windows operating system provides for ease of use as well as flexibility in integrating the machine into a true CAD-CAM environment. It is equipped as standard with a 17” color monitor, RS-232 serial port, 48 x IDE CD-ROM and a 3.5” 1.44MB ( LS 120) floppy drive. The software provided with the machine will allow it to elaborate DXF files generated from common CAD systems and the integrated CAM package will allow the elaboration of these DXF files into machine programs seamlessly. The software will also allow the customer to create his own programs without a CAD program at the machine or in the office. The machine comes standard with one (1) key and Office version software that willenable the customer to install the software on his

office PC and generate programs in the office and then transfer them to the machine via the floppy drive or hard wiring to the machine.

The PC based control also has the following features;

Helical interpolation

Parametric programming

Interactive graphic editing for all machining functions with automatic optimization of machine movements.

Background editing allows programming / editing to take place while the machine is running.
