Common Faults of Double-Ended Chamfering Machines

1. Machining Accuracy Faults

Chamfering Eccentricity, One Side Larger Than the Other: Check if the workpiece's outer diameter matches the fixture size. Adjust the clamping die position to ensure concentricity with both machine heads.

Unstable Chamfering Length: For CNC models, check if the ball screw and servo motor connecting shaft are loose. For pneumatic/hydraulic models, adjust the feed delay to ensure the cylinder/pneumatic cylinder stroke is fully completed.

Unsmooth Chamfered Surface: Match the tool sharpness to the material being machined. Use high speed for soft materials and low speed for hard materials.

2. Abnormal Motion Faults:
Normal Manual Mode, Automatic Mode Not Working: Often due to misalignment of the limit switch/magnetic switch. Adjust the sensor position. If the indicator light is not on, replace the sensor directly and check the corresponding relay status.

Abnormal Vibration: Check if the spindle bearing is loose or damaged, and if the spindle bushing is worn. Replace worn parts promptly and eliminate spindle clearance.

3. Basic Operational Faults

No Response Upon Power-On: Check the power supply for looseness, the internal circuit breaker for closure, and the power input to the display screen for normal operation. Also check for mechanical parts that may be stuck.

Excessive Operating Noise: Adjust the equipment to a horizontal position, stop the machine, and tighten any loose screws on the clamps to prevent unstable workpiece clamping and resulting noise.

4. Mechanical Jamming Faults
If the equipment makes abnormal noise or jams, first check if the grease has dried out. Clean the guide rails and then add the appropriate grease. Use an air gun to blow away any accumulated metal debris from the worktable and transmission gears. Run the spindle idle to check for bearing wear.
