Vallorbs Jewel Co has experienced technicians and the technical capability to perform numerous secondary operations such as, milling, broaching, gun drilling, thread rolling, as well as a variety of surface finishing for screw-machined parts. Small components are finished to super fine or rough textures through high quality burnishing, lapping, and surface grinding.

Our gundrilling capabilities are holes from 0.078" to 1.250" diameter and up to an 11" uninterrupted depth with clamping capabilities on round, square, or hexagonal bar stock. Total part depth of 22".

Offering micro finishes down to 4 µ inches (0.10 µ M finish) makes our lapping services distinctive for small intricate parts. We use a Sunnen MBB-1650 Horizontal Honing Machine to provide internal honing, with light abrasives such as silicon carbide, aluminum oxide, cubic boron nitride (CBN), as well as diamond hone stones.
