GRM/GRA Series - C-Frame Single Crank Power Press (Variable Slide Stroke)

Product Description

One-piece, full-length, box type gibs assure actuated slide guiding. Force is delivered vertically, minimizing lateral thrust and, consequently, reducing off-center loading and friction in the gibs.

GRM series is designed to resist deflection, and provide accurate pressings and longer die life, even at full tonnage loads. The heavy, one-piece welded steel frame is fully stess relieved and designed to provide a stable base for the GRM series presses.
