The surface of metal parts worked through turning, reaming or boring operations is a succession of “PROJECTION or PEAKS” and “INDENTATION or VALLEY” when microscopically examined (see fig. 1). The roller Burnishing Operation compresses the “Projection (Peaks)’ into the “Indentation” (Valleys) thus forming a smooth mirror finished surface (as in fig. 2). Any material not exceeding 40 Rockwell Hardness “C” can be rolled bumished.

Precision-engineered CNC & VMC machine toolings and accessories designed for reliable performance, accurate machining, and efficient industrial operations.
A jig’s primary purpose is to provide repeatability, accuracy, and interchange ability in the manufacturing of products. A jig is often confused with a fixture.
We make multi Head Spindle for the purpose of more than one hole at single operation at different P.C.D. as per your requirements with grease or oil.
The surface of metal parts worked through turning, reaming or boring operations is a succession of “PROJECTION or PEAKS” and “INDENTATION or VALLEY” when microscopically examined (see fig. 1).
The VMC Machine Spindle Cartridge is a precision belt-driven spindle unit designed for reliable and accurate machining performance. With spindle nose accuracy strictly maintained below 0.007 mm, it supports a wide range of machining operations.
