Diamond and CBN Profile Grinding Wheels

July 11, 2018
LACH DIAMOND's grinding wheels now offer a tool life of 25X longer than previous versions.

The technology of contour-profiled grinding wheels is at the same time the comeback of metal binders for LACH diamond and CBN grinding wheels.


The resin bond grinding wheel needs several processing steps during the deep grinding of components made of carbide, high-alloyed steels or ceramics, such as aluminium oxide, magnesium oxide or else non-oxide ceramics, such as silicon nitride. The new metal bond contour-profiled profile grinding wheel now accomplishes these works in one single step time- and cost-saving. Almost every profile type, concave or convex, is possible – even with smallest tolerances of up to 0.005 mm.


Costs for abrasives and wheels could be reduced by a factor of 8 – one single profiled contour-profiled grinding wheel is sufficient for all so-far necessary set of wheels. Tool life is now up to 25 times longer, e.g. for solid carbide thread inserts. The contour-profiled wheels achieve up to 35 to 60% time-savings through higher feed rates per work-piece.
