Economy, composite set consists of 30 specimens 7/8" x 3/8" of electroformed solid nickel. Each type of surface finish, such as flat lapping, reaming, grinding, horizontal milling, vertical milling, and turning, is truly and consistently reproduced to give the operator or designer a realistic idea of the feel, appearance, and texture of the machined components. A set of instructions is included with each set. Quick and easy comparisons can be made, eliminating costly checking methods, saving valuable production time, and stopping the production of scrap caused by poor finishes.
The scale conforms to S.A.E. and military specifications for visual and tactile inspection.
Made of solid electroformed nickel, the set has markings in AA (microinches) and metric in Ra (micrometers).
Item No. SU-010010 is for use in the drafting room, engineering department, or in shop.
