A linear guide, the ball screw, or the ball nut is damaged:
Before removing the waycovers, make sure these items on the machine are within specification. If they are not, make adjustments and test the machine.
- Machine Level
- Alignment of the Spindle
- Alignment of the Turret
- Alignment of the Tailstock
If the problem continues, remove the way covers and examine the linear guides, the ball screw, and the ball nut for damage, movement, or signs of a crash.
Note: Damaged or loose bearings in the trucks for the linear guides can cause the machine to chatter during aggressive cutting. The linear guide pads on the machine should not have any side to side / up and down movement over 0.002".
If the linear guides, the ball screw, or the ball nut are damaged or loose, replace them.
