What could be causing head noise on my XYZ Machine Tools Power Tool?
- A
  Amanda GlassSep 13, 2025
  Possible causes for head noise on your XYZ Machine Tools Power Tool include: * **Machine Setup or Tooling:** If the noise is most evident under load (cutting situations), examine the setup and tooling being used. * **Upper Spindle Bearing:** Remove the upper bearing plate above the spindle to inspect a worn upper spindle bearing. * **Spindle Bearings:** A high-pitched sound, most evident at high RPMs, indicates worn spindle bearings. * **Belt Alignment:** Ensure the 10 ribs on the belt are aligned with the 10 grooves on the 2 pulleys.

What causes the axis to search on my XYZ Machine Tools SMX 4000 Power Tool?
- T
  Tanya MendezSep 6, 2025
  An axis searching on your XYZ Machine Tools Power Tool can be caused by: * **Backlash Compensation:** Check physical backlash in the system and re-enter it in code 128, as excessive backlash compensation is a common cause. * **Feed Forward Values:** Check ball screw torque if high feed forward values are present. * **Friction:** Ensure proper lubrication, gib adjustments, and unlocked gib locks to address excessive friction in the sliding ways. * **Drive Train:** Check the drive train of the axis that is searching for any looseness.
