Grinding

Centerless grinding is a method of material removal through grinding, similar to centered grinding except for the absence of the spindle. It has high through-put, i.e. large number of parts can be manufactured in a short time. The parts are set up between the regulating wheel (or back up wheel) and the grinding wheel, and is supported by the work blade (or work rest). The wheels are rotated in opposite directions.. The work rest is located between the wheels. The work is placed upon the work rest, and the latter, together with the regulating wheel is fed forward, forcing the works against the grinding wheel.

Blanchard Grinding

Blanchard Grinding is high precision rotary surface grinding which allows for rapid removal of material without compromising customer requested dimensions. We grind ferrous materials utilizing a magnetic chuck. Our Blanchards leave the trademark cross-hatched surface finish pattern typically within a 32-125 finish.

Double Disc Grinding

Double Disc Grinding uses two abrasive discs to remove even stock on two opposite and parallel sides of product components. The grinding of two sides, simultaneously, reduces handling and eliminates the extra grinding time, speeds production and provides consistency over the entire run of parts.
