Common faults and solutions of CNC punching and shearing machines
1、 Cutting accuracy decreases
Cause of malfunction:
1. The CNC punching and shearing machine blades are worn or loose.
2. The positioning pin is worn or loose.
3. The tool clamp is not tight.
4. The limit switch is not sensitive to induction.
Solution:
1. Replace worn blades in a timely manner and tighten loose parts.
2. Adjust the position of the locating pin or replace the worn locating pin.
3. Check the tool clamping mechanism, adjust the spring pressure or replace worn parts.
4. Adjust the position of the limit switch to make it sensitive to sensing.
2、 Tool wear
Cause of malfunction:
1. The tool material is too hard or too soft.
2. The blade angle is incorrect.
3. The tool speed is too fast or too slow.
4. Incorrect installation or improper use of blades.

Solution:
1. Choose a suitable cutting tool for processing materials and adjust the blade angle.
2. Adjust the speed of the CNC punching and shearing machine to meet the processing requirements.
3. Check the installation of the cutting tools and ensure that they are used correctly.
4. Reasonably select the type of cutting tool and blade material based on the processing material and thickness.
3、 Abnormal noise
Cause of malfunction:
1. Damaged or poorly lubricated bearings.
2. There are foreign objects or gear wear inside the gearbox.
3. Motor malfunction or loose drive belt.
4. Overload or excessive number of cuts during cutting.
Solution:
1. Check the bearings and lubrication system, and replace damaged bearings and lubrication components in a timely manner.
2. Clean the gearbox and replace worn gears. Check the position of the drive belt and adjust the position of the motor.
3. Check the motor and transmission belt, adjust the cutting speed and number of cuts.
4. Reasonably select appropriate machining parameters and tools according to machining requirements.
4、 Computer crashes
Cause of malfunction:
1. System files are damaged or missing.
2. Software conflicts or virus impacts.
3. Poor heat dissipation or excessive dust.
4. System hardware failure.
