Both ends of the workpiece are larger and have a saddle shape
Reason:
1.The grinding wheel of the cylindrical grinder has too little excess over the end face of the workpiece;
2.The dwell time of the cylindrical grinder table is too short;
3.When grinding the long shaft, the top of the top is too tight;
4.The pressure of the horizontal support block of the center frame of the cylindrical grinding machine is too high;
Solution:
1.Correctly adjust the position of the reversing collision block on the worktable of the cylindrical grinding machine, so that the grinding wheel of the cylindrical grinding machine exceeds the width of the grinding wheel by 1/3-1/2 of the end face.
2.Tangent adjustment of the dwell time of the cylindrical grinder table;
3.Adjust the top pressure of the cylindrical grinder.
4.Correctly adjust the position of the horizontal support block of the cylindrical grinder center frame.
