With the Rocklinizer micro battery-operated carbide applicator from Rocklin Mfg. Co., the spark deposition process applies extremely hard and wear resistant coatings ranging from 60 to 80 HRC onto metals, tools and dies. The lithium-ion battery delivers about 3 hours of use in one charge and can be rapidly recharged. Alternatively, the 10-lb. unit can also be used while plugged in. The unit solves an array of wear and gripping issues including eliminating slug pull back in stamping dies, extending the life of cutting surfaces and enhancing gripping surfaces on collets, clamps and robot grippers.
