Don't be afraid of encountering these three major defects of cylindrical grinding machines again!
1、 The workpiece of the CNC cylindrical grinder is prone to bending during grinding.
Reason for analysis:
1. The grinding amount is too large during external cylindrical grinding.
2. When grinding on an external cylindrical grinder, there is insufficient supply of cutting fluid.
Protective measures:
1. Reduce the back cutting amount of the external cylindrical grinder appropriately.
2. Ensure sufficient supply of cutting fluid.
2、 The outer circumference of the shoulder is relatively large.
Reason for analysis:
1. The dwell time of the reversing worktable of the external cylindrical grinder is too short.
2. The grinding wheel of the external grinder is worn and the outer angle of the grinding wheel becomes rounded.
Protective measures:
1. Increase the dwell time for reversing the worktable of the cylindrical grinder.
2. Timely correction of the grinding wheel of the CNC cylindrical grinder is necessary to ensure the accuracy of workpiece grinding.
3、 The dimensions at both ends of the workpiece are large and saddle shaped.
Reason for analysis:
1. The grinding wheel of the external cylindrical grinder has too little excess on the workpiece end face.
2. The dwell time of the cylindrical grinder worktable is too short.
Protective measures:
1. Correctly adjust the position of the reversing collision block on the worktable of the external cylindrical grinder, so that the grinding wheel of the external cylindrical grinder extends beyond the end face by 1/3-1/2 of the grinding wheel width.
2. Tangential adjustment of the dwell time of the external cylindrical grinder worktable.
