NO. 9203

The Instrument Bench Center is specifically designed for speed, accuracy, and versatility in checking miniature and sub-miniature parts machined on centers. When placed horizontally on a surface plate of known flatness, the centers line up automatically within close limits, and a quick turn of a knurled knob locks them in position. The entire unit may then be turned up on end to check runout and squareness of shoulders and sides of grooves.

An unusual feature of the No. 9203 is an adjustable headstock center point that may be rotated to bring the workpiece centers perfectly parallel to the surface plate. This allows the inspector to obtain a precise reading of concentricity and parallelism in a horizontal plane, and shoulder runout in a vertical plane. When using the unit standing on end (vertical position) always present the gaging head square to the bed axis and in line with the axis of the headstock and tailstock centers.


The headstock and tailstock are made of high quality alloy steel and scientifically heat treated for maximum stability. They are machined for precise alignment of the 3/8" x 60 hardened and ground tool steel centers. The aligning shaft is made of tubular steel, 1-1/8" O.D., and is chrome plated for resistance to rust and wear. Finished wood case with hinged cover available upon request.
