CNC cylindrical grinder of skills of solving grinding defects

CNC cylindrical grinding machine to solve grinding defects skills, engaged in grinding machine must see

1、 The workpiece is easy to bend when grinding on CNC cylindrical grinder

Reason analysis:

1. The grinding amount is too large in cylindrical grinding;

2. When grinding with cylindrical grinder, the supply of cutting fluid is not enough;

Preventive measures:

1. Reduce the back feed of cylindrical grinder properly;

2. Ensure sufficient supply of cutting fluid;

2、 The size of the outer circle beside the shoulder of CNC cylindrical grinder is large

Reason analysis:

1. The dwell time of reversing table of CNC cylindrical grinder is too short;

2. The grinding wheel of cylindrical grinder is worn and the external angle of grinding wheel becomes round.

Preventive measures:

1. Extend the dwell time of cylindrical grinder table reversing.

2. Correct the grinding wheel of CNC cylindrical grinder in time to ensure the accuracy of workpiece grinding.

3、 The size of both ends of CNC cylindrical grinder is large and saddle shaped

Reason analysis:

1. The surplus of the grinding wheel of CNC cylindrical grinder is too little out of the end face of the workpiece;

2. The dwell time of cylindrical grinder table is too short;

3. When grinding the long shaft, the top of the top is too tight;

4. The pressure of horizontal support block of center frame of cylindrical grinder is too high;

Preventive measures:

1. Correctly adjust the position of the reversing block on the working table of the cylindrical grinder, so that the grinding wheel of the cylindrical grinding machine is 1 / 3-1 / 2 of the grinding wheel width of the end face.

2. Tangent adjustment of cylindrical grinder table dwell time;

3. Adjust the center pressure of cylindrical grinder.

4. Adjust the horizontal support block position of center frame of cylindrical grinder correctly.
