Produced by holding CVD thick film rectangular diamonds in arrays on a metal base with plated metal. The CVD thick film rectangular column has no anisotropy and the area of diamond acting on the whetstone face is always constant, maintaining stable dressing performance. Moreover, the most suitable dressing performance can be obtained by changing the size of the rectangular column and the number of the array.
Used for traverse dressing of general whetstones and CBN wheels used for internal grinding of various bearings, automobiles, machine parts, etc.
