R.A.D Auto Machine has Invested in Rottler CNC Engine Blueprinting and Machining Equipment for Precision Block Probing and Blueprinting. Cylinder Bore finish ie. crosshatch, size control and surface finish are critical. The Rottler  HP6A Computerized Diamond Hone  will produce exact cross hatch patterns while meeting specific RA Finish requirements. Holding .0001 roundness and straightness is a bonus and achievable with the HP6A. Our Rottler equipped Valve department enables us to achieve tolerance of .0002 concentricity on the Valve Face and Valve Seat diameter.
