Analysis of difficult problems in cylindrical grinding

Analysis of difficult problems in cylindrical grinding

 

 

1.The workpiece of the cylindrical grinder is easy to bend during grinding

 

Analysis reason: 

-The grinding amount is too large during cylindrical grinding; 

-Inadequate supply of cutting fluid during cylindrical grinding;

 

Precaution:

-Appropriately reduce the back cutting depth consumption of cylindrical grinders

-Ensure adequate supply of cutting fluid

 

 

2.Large outer circle beside shaft shoulder

 

Analysis reason:

- Cylindrical grinder reversing table stay time is too short

- Grinding wheel of external cylindrical grinding machine is worn and the outer Angle of grinding wheel becomes round

 

Precaution:

- Extend the residence time of reversing of the cylindrical grinder.

-It is necessary to correct the grinding wheel of CNC cylindrical grinder in time to ensure the precision of workpiece grinding.
