Often, during the final finish and repair of hardened tools, common abrasives just don’t “cut it,” according to DW Sales. The company provides specialty stone solutions designed to cut through 55 Rockwell hardness and higher to meet these surface treatment needs, including CNB stones and diamond Ceramic Super Stones.
The CNB stone, comprising fine ceramic fibers encased in glass and sandwiched into a stick form, easily cuts hardened tool steels and welds. It is commonly used in an air profiler, like the UTR-70. However, DW Sales notes that caution needs to be used with this abrasive technique, as CNBs can cut deep and fast. Once the high spot of the weld is close to removed, the surface finish can be blended in with finer diamond super stones.
Diamond Ceramic Super Stones are available from 180 to 600 grit and in three widths. Comprised of a ceramic fiber impregnated with diamond grains, DW Sales says these finer stones make finishing hardened steel and/or harder welds an easier task.
