In terms of time and cost flute grinding is one of the mostdemanding tool grinding processes.

To significantly improve the grinding efficiency, apart fromchoosing a suitable coolant, and the grinding wheel propertiesare crytical in order to optimise the potential of high perform-ance grinding machines.

The material removal rate Q´w, calculated from depth of cut aeand feed rate vt, gives a clear indication of wheel performance.

Standard wheel cutting performance has been limited by highcutting forces and resulting heat generation. Under these con-ditions damage is common on both to the workpiece and thewheel despite ideal coolant application.

The above problems can be resolved using new bond formu-lations which display the following advantages:

During extensive testing on various machines, impressive mate-rial removal rates of up to Q´w 15 mm³/mm*s were achieved.

Currently two bond types are available:

Excellent cutting characteristics and form stability due to high grit retention

Impressive thermal resistance

Elevated grinding performance due to good heat removalduring the grinding process
