Technical Specifications:

Standard CMNS Flat Stamps are engraved as sharp face characters. This type of face style is engraved with a sharp edge. A sharp face tool penetrates more easily than other styles.

Dot Style Characters are engraved with a series of conical dots for the lowest possible stress when marking. Recommended for high pressure fittings, aircraft, and other parts where sharp tools might disrupt the molecular structure of the metal.

A starting cam may be required for some CNC roll marking operations. The purpose of the starting cam is to provide a “ramp” into the marking legend and extend the life of the marking dies. The carry dots take the first impact of the marking legend. CMT suggests about a 3/4” [19mm] length for the starting cam. Longer and shorter length are available.
