  1. Quick Troubleshooting Steps

  • Check the clamping pressure: Ensure the pressure plate or collet applies even force; too much or too little pressure will jam the bar. Adjust the pneumatic or hydraulic release mechanism accordingly.
  • Align the material path: Verify that the bar feeder, guide bushing, and spindle centers are collinear; any offset will cause the bar to twist or wedge.
  • Inspect belts and rollers: Belts must be tensioned correctly—loose belts slip, over-tight belts bind. Replace worn rollers immediately.
  • Lubricate moving parts: Clean and grease the eccentric shaft, release cam, and pusher fingers; lack of lubrication is a common cause of seizure.

2. Targeted Remedies

  • Servo/stepper motor issues: If the motor stutters or fails to rotate, check connector integrity and driver board components (transistors, diodes).
  • Tool interference: Confirm that guide bushings and cutting tools are not obstructing the bar; a tool returning beyond its home position can jam the stock. Clear chips from the gear train.
  • Spindle/collet over-clamping: Reduce the collet closing force; excessive clamping prevents the bar from advancing and leads to a jam.

3. Preventive Measures

  • Routine maintenance: Clean the bar-feed channel and lubricate slides daily to prevent chip accumulation.
  • Operator training: Standardize loading procedures to avoid misaligned bar insertion.
  • Material quality: Use straight, size-compliant bar stock; reject bars with burrs or ovality.
