FEATURES:
Our economy, composite Set No. 16008 as shown here 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
so as 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. By means of this set,
or one of our individual (larger) standards specimen scale sets, quick and easy comparisons
can be made, thus eliminating costly checking methods, saving valuable production time, and
stopping the production of scrap caused by poor finishes.
