1 Assembly and maintenance instruction recirculating ball screw
Recirculating ball screw
The delivery of the ball screw nut and spindle is performed corrosion-proof and ready-for-assembly.
The ball-type linear are precision parts and need to be treated with outmost cleanliness andcare.
Please unpack the ball screw spindle directly before assembling.
1.1 Installation with spindleThe ball screw spindle needs to be installed radial and stressfree: While tightening the bea-rings, you need to move the slide to and fro on the corresponding side.
1.2 Lubricating notesGeneral notesPlease consider the used lubricant as another machine element. Beside the careful design ofthe ball-type linear drives the lubricant is mainly required to achieve the technically possible ser-vice life.
For most applications, the lubricant is a wearing part and needs to be added accordingly.
As a matter of principle, a ball-type linear drive cannot be perfectly sealed, since there arealways parts of the running path which back out of the protected area. This way, dust and othersoilings of the environment are taken up which adhere to the greasy surfaces and provide foradditional lubricant consumption. A part of the soilings get into the nut and make the lubricantthicken. Thus, the serviceability of the lubricant is decreasing which needs to be compensatedby the lubricating.
Before commissioning the spindle imperatively lubricate the whole length of the threadwith thehelp of the nut.
Due to the axial movements between the nut and the spindle the loss of lubricant is higher thanfor rolling bearings. Therefore, it is not possible to perform a lifetime lubrication.
Lubricating
In order to maintain the functional capability of the ball screws, they need to be lubricated suf-ficiently. You may use the same lubricants as for rolling bearings. Lubricants containing MoS2 orgraphite must not be used. The choice of the lubricant and the kind of application can generallybe adapted to the lubrication of the other machine components. According to experience, a sin-gle lifetime lubrication of the ball-type linear drives is not sufficient since the spindle alwaysdischarges small amounts of lubricants off the nut.
Greasing
Use greases with EP additions (KP2K, DIN 51825). The regreasing interval is depending on theenvironmental conditions. Generally, it is necessary to regrease every 200 to 600 operatinghours (about 3 months). It applies as standard value for the regreasing quantity: per each 1 cmspindle diameter 1 cm³ grease per nut. Only use greases of the same saponification basis whenregreasing. If you use any greases of another saponification basis, it is necessary to clean therecirculating ball screw and the spindle nut.
When you have regreased once, you should move the slide completely to and fro in order tomake sure that the grease will be uniformly spread over the ball screw spindle and in the nut.Then you should regrease once again.

This list is a recommendation without engagement.
1.3 Notes regarding the storageBall-type linear drives are susceptible to damages and soiling. They need to be stored at a dryplace. The spindle needs to be supported in a way that it cannot bend.
Protect the lubricated ball-linear drive from dust and chips.

1.6 Converting to a recirculating ball screw
INFORMATION
When assembling the BF20 and BF20L from trapezoidal threads to recirculating ball screws, it ispossible that the travels of the X-, Y- and Z-axis are changing.
1.6.1 Disassembly X-axis
Start disassembling on the left side of the drilling-milling machine.
Unscrew the hexagon nut from the spindle.

INFORMATIONFor older versions of the BF 20, the pil-low block of the Y-axis is a little smaller.In this case, you should use the longersupporting bushings (included in theCNC add-on kit part No. 4).
For new versions (from 2007 on) of the BF 20, the pillow block is built stronger. Use the attached small sup-porting bushings (included in the CNC add-on kit part No. 11). If they are not included in the delivery, turn the lar-ger supporting bushings off to 14 mm using a lathe with the help of the pro-duction drawing (part 2). The rear of the housing should be flush with the shaft end of the pillow block as illu-strated.
„Production drawings“ on page 40
Put the small or the turned off suppor-ting bushings into the holes of the pil-low blocks.
Mount the housing of the Y-axis using the attached fixing material. Please make sure that you only screw in the hexagon socket screws, but do not tighten them yet.

Put the support of the Y-axis on the spindle nut.
Fix the support to the spindle nut using the hexagon socket screws. Apply a securing mean before screwing the hexagon socket screws.
Clamp the fixture. Before clamping the fixture, turn the cross table once completely to the front and to the back. Clamp the support to the front position of the cross table.
When mounting the CNC kit you should no longer use the clamping lever to clamp the table since they might possibly interfere when traveling the axis. Use hexagon sok-ket screws with counternuts instead.
Now fasten the hexagon socket screws on the housing.
Now mount the remaining parts of the CNC add-on kit (CNC conver-sion instructions).

Position the slide above the sup-port. Fix the slide of the Z-axis using the two hexagon sokket screws.
If required, adjust the distance of the spindle and of the spindle nut using the locking screws and in doing so adjust the smooth running of the spindle.
Fix the pillow block of the Z-axis once again.
When assembling the CNC kit, you should no longer use the clamping levers for the table clamping, since they possibly might interfere when traveling the axis. Use hexagon sok-ket screws with counternuts instead.
