Overview

Our consistent high quality has been built upon by our total commitment and complete specialization to the production of supreme quality valve seat and guide machines exclusively. Our unique production facility uses the most advanced manufacturing techniques and is governed by most rigid quality control.

Robins exclusive patented multi-angle seat tooling eliminates the need for bounce springs. Robins patented tooling holds the ball driver firmly, yet allows the sphere to float during seat cutting. This eliminates the troublesome bounce springs but gives you the ultimate in valve seat concentricity.

Robins machines offer a wide range of tooling & fixtures for machining a variety of cylinder heads as well as all the required operations from seat cutting, guide finishing to injector tube machining.
