Fine Grinding Tools

For surface finishing of very hard materials

Fine Grinding Wheels and Mounted Points

are mainly used for the fine grinding of very hard materials. They are available in 'fine' and 'medium' grades.

We recommend the following rotary velocity (surface speed):

  • type 'fine':         1 - 5 m/s

  • type 'medium':   3 - 15 m/s

For cooling and rinsing; paraffin, cutting oil and emulsion are recommended.

The correct dressing of the wheels should be done on the working spindle by diamond-wheels, diamond multi-grained dressers or by Boron Carbide handlappers.  The selection of the dressing wheel grain size depends upon how fine or coarse the surface should be. Single dressing diamonds are unsuitable. To clean the tools most efficiently a felt moistened with paraffin should be rubbed on the surface.

 

Fine Grinding Wheels

Are available in ‘fine’ and ‘medium’ grades.

If not otherwise stated on the order, wheels with metal bushings will be supplied.

Mounted Points

are especially suitable when working on hard materials.

FRIALIT-DEGUSSIT mounted points are available in type 'fine' and 'medium'.

When working with mounted points, care must be taken to ensure that the speed will not be too high.

FRIALIT-DEGUSSIT mounted points are adapted best for use in infinitely variable grinding machines

A better grinding effect is achieved by lower speeds; a better polishing effect by higher speeds.
The following speeds are recommended;

  • type 'fine':         1 - 5 m/s
  • type 'medium':   3 - 15 m/s

The correct dressing of the mounted points should be done on the working spindle by diamond-wheels, diamond multi-grained dressers or by Boron Carbide handlappers.  The selection of the dressing wheel grain size depends upon how fine or coarse the surface should be. Single dressing diamonds are unsuitable. To clean the tools most efficiently a felt moistened with paraffin should be rubbed on the surface.
