Machine Style

GT SCHMIDT manufactures a variety of machine style type holders and die holders for use in press marking and roll marking applications.

Our machine style type holders accommodate all our straight, round, and wedge style steel type. 

GT SCHMIDT machines use t-bolt and dove-style die holders for flat and rectangular marking dies, as well as knurl support carriages for round solid lettering knurls.

Machine style type holders and die holders are made from selected tool steel and carefully heat treated to provide rugged quality construction with uniform impressions.

Roller Bearing Cradle

Roller bearing cradles are fixtures that can be mounted on the tables of roll markers to support and locate solid round parts or heavy walled tubing for peripheral marking.

Parts are loaded on these fixtures manually and peripheral impressions are made using flat stamps or straight type holders mounted in a machine slide. Stamps roll over the periphery of the part causing it to rotate while marking. Standard cradles are carried in stock; custom cradles designed according to your specs are made to order.
