The primary function of the Bench Centre is to check different geometric tolerance such as cylindricity and runout. In addition to this, bench centre is also used to measure the pitch circle diameter of gears.

With our PCD attachment, the PCD of a gear can be measured accurately. The simple mechanism allows the operator to inspect a large number of parts in a relatively short time with better accuracy.

A granite bench centre comprises of a granite surface plate with dead centres fixed at one end of the surface plate. The dead centres move over a cast iron insert that is placed after carving out the granite to make it on an even working surface as the rest of the plate. It is suitable for measuring the geometric tolerances of complex parts which cannot be placed over a standard bench centre, the surface area of the plate can be used to rest those parts.
