XYZ Bed Mill Safety, Installation, Maintenance, Service & Parts List Manual
4.1.2 A Special Word About X/Y/Z Gibs
The slideway surfaces are vital to the performance of the bed mill.
Gibs should be:
flat
free of twist
free of burrs
free of blockages in the oil passages and channels
Defective or scarred gibs must be replaced. Shimming of gibs will not yield acceptable results.
It is good machining practice to avoid the use of shop air to clean the swarf off a machine. This risks
blowing swarf into the sliding way surfaces and compromising the performance of the machine.
Gibs that are not adjusted correctly will affect the performance of the machine. It will lead to positioning
and repeatability problems. The gibs should be adjusted at least twice a year.
See Gib Adjustments Section 5.2.1.
4.1.3 Lubrication
Lubrication is one of the single, most important maintenance issues and plays a key role in assuring the
performance and durability of the bed mill. At the beginning of each day manually supply oil to the way
surfaces.
Lack of lubrication can lead to a variety of problems with your machine motion due to increased friction in
the sliding ways. This increased friction may lead to part inaccuracies and decreased life expectancies of
your ball screws and way surfaces.
4.1.4 Machining Set-Up
The machining set-up itself is always something that can greatly influence the performance of the mill.
The following are some things to keep in mind:
Driving and cutting forces cause deflections, since no
material is totally rigid
