- Replace wipers on the trolleys of the linear guides
Carrying out the maintenance activities described below requires
special knowledge. For this reason, these maintenance activities
must only be carried out by staff that has received adequate training
by the machine manufacturer!
Orientation
The wipers on the trolleys of the linear guides prevent the ingress of dirt into the
ballscrew. The outer wipers of the trolleys are easily accessible and thus can be
replaced quickly. It is also possible to push out the entire trolley under the tool slide
to replace the two wipers. Damaged guide bars may have a negative effect on the
machining result of the lathe or on the surface of the workpieces.
Procedure
1. Move the tool slide to an appropriate position.
2. Replace outer wipers. Loosen screws of wipers accessible from the outside
and remove the wipers. Replace wipers.
Alternatively, the following procedure can be used!
Replace external and internal wipers. Loosen and remove screws of the
accessible trolley. Always remove one trolley and replace one wiper after the
other.
3.
Do not push trolley from the guide bar. Balls of the linear ball
bearing may be lost.
Push out trolley carefully under the tool slide.
4.
New wipers must rest against the contour of the guide bar.
Replace inner and outer wipers.
5. Push the trolley back under the tool slide and tighten the screws.
