This guide helps operators identify and resolve common issues with Xinmei CNC machining centers. Regular self-inspection can prevent major breakdowns and maintain optimal machine performance.
Before You Start
Before troubleshooting, always ensure:
- Record the alarm code or error message displayed
- Note any unusual sounds, vibrations, or smells
- Check recent program changes or parameter modifications
- Review maintenance history for related issues
1Spindle Issues
Common spindle problems and solutions:
Spindle Does Not Start
Possible causes: Emergency stop engaged, door interlock triggered, spindle drive fault
Solution: Check E-stop status, verify all doors are closed, reset spindle drive if alarm present
Spindle Speed Unstable
Possible causes: Belt tension loose, bearing wear, encoder malfunction
Solution: Adjust belt tension, check bearing condition, inspect encoder connections
Excessive Spindle Vibration
Possible causes: Unbalanced tool holder, worn bearings, loose spindle components
Solution: Balance tool assembly, replace bearings if worn, tighten all fasteners
2Axis Movement Issues
Troubleshooting axis movement problems:
Axis Does Not Move
Possible causes: Servo drive alarm, limit switch triggered, mechanical obstruction
Solution: Clear servo alarm, check limit switch status, inspect for physical blockage
Axis Movement Jerky
Possible causes: Low servo gain, way cover interference, lubrication issue
Solution: Adjust servo parameters, inspect way covers, check lubrication system
Positioning Error
Possible causes: Ball screw backlash, encoder drift, thermal expansion
Solution: Adjust backlash compensation, recalibrate encoder, allow warm-up time
3Tool Changer Issues
Resolving automatic tool changer problems:
Tool Not Clamped Properly
Possible causes: Low clamping pressure, contaminated taper, worn collet
Solution: Check hydraulic/pneumatic pressure, clean taper surfaces, replace collet if worn
Tool Change Timeout
Possible causes: Magazine position sensor fault, arm movement blocked, low air pressure
Solution: Verify sensor operation, clear obstruction, check air supply pressure
4Common Alarm Codes
Quick reference for frequently encountered alarm codes:
Alarm Code Reference
E001-Emergency Stop Active: Release E-stop button and resetE010-Spindle Overload: Reduce cutting parameters, check for tool wearE020-Servo Alarm X/Y/Z: Check motor connections, reset servo driveE030-Lubrication Error: Refill lubricant, check pump and linesE040-Coolant Level Low: Add coolant, check for leaksE050-Air Pressure Low: Check compressor, inspect for leaksWhen to Contact Service
