Logarithmical relief ground

(constant profile)

All GLOOR cutters with logarithmic relief grinding retain a constant profile from until the cutters are completely used up.

Normally the form cutters are made with straight fluted teeth, but on request GLOOR can also manufacture these cutters helical fluted with logarithmic relief grinding.

Normally the profiles are logarithmical relief ground in the radial direction of the cutter. In the case of one sided profiles, we are able, on request, to grind logarithmically in the radial as well as in the slight axial direction of the cutter at the same time (keeping a constant profile).

 

A = constant clearance angle B = constant cutting angle C = resharpened teeth, the cutting angle and profile remain constant
