Design and Operating Principle
GRM clamps are used on press-line and body-shop tooling to clamp sheet metal edges during transfer. A pneumatic cylinder drives a cam or toggle that closes the jaw, and locking in the closed position means the panel stays clamped if air is lost.
Adjustable rotation stops let one clamp model open to different angles, adapting to part clearance needs.
Integration and Selection
Choose jaw style and tip for each clamping point, set rotation stops and add switches.
Use standard tips across tooling.
