Common problems of CNC lathes mainly include mechanical faults, electrical control faults and processing abnormalities. The following are the specific manifestations and solutions:

Mechanical failure

The accuracy of the ‌ spindle decreases ‌

Long-term use leads to bearing wear, increased ball screw clearance or thermal deformation, which is manifested as decreased dimensional accuracy of the workpiece and surface roughness exceeding the tolerance. It is necessary to check the lubrication conditions of the bearings and guide rails. If necessary, replace the worn parts.

80% of cases are caused by the breakage of the guide pin or the damage of the Hall element. It is necessary to check the freedom of the guide pin, the voltage of the Hall element (normal 24V), and the connection of the circuit. ‌

Oil pump failure ‌

Insufficient oil pressure can lead to a decrease in the accuracy of machine tools. It is necessary to check the oil level and the clogging condition of the filter screen, and replace it with inferior oil.

Youdaoplaceholder0 power module abnormality ‌

If the system fails to start or restart, it is necessary to check the stability of the external power supply, the status of the fuse and surge absorber, and replace the damaged components.

Servo system alarm ‌

This includes abnormal motor noise, non-operation or positional deviation. First, check the mechanical jamming condition. Through system diagnosis, view the error value and calibrate the parameters.

Handwheel malfunction ‌

Check for poor contact of the shaft selector switch (accounting for 40%), damage to the pulse disk or broken connection lines, and enter the system diagnostic interface to detect the contact status.

Processing anomaly

Youdaoplaceholder0 flaking problem ‌

When processing high-hardness materials, band-shaped chips are prone to wrap around the cutting tools. It is necessary to adjust the cutting parameters (reduce the rotational speed, increase cooling) or replace the wear-resistant inserts.

Plastic deformation ‌

If the blade deforms due to high temperature or softening of the base material, the cutting speed should be reduced, highly wear-resistant blades should be selected and cooling should be strengthened

It is recommended to carry out regular maintenance: Check the lubrication of the guide rail every week, correct the coaxiality of the motor and the lead screw, and replace the deformation protection cover in time. This can reduce the maintenance cost by five times.
