Why GRM 80B?

Standardised tooling concept

The bushing tool consists of a basic tool, two tool-holder sets and the active parts. According to the manufacturer, tool change-over times are very short, and for international use only the active parts need to be shipped.

Straight and flanged bushings

Up to 220 1/min for cylindrical straight bushings and up to 160 1/min for flanged and collar bushings; bushing inner diameter 15–40 mm, bushing length up to 50 mm.

Servo feed and VC 1E

The RZV 2.1 servo feed feeds the strip material to the machine; operation is via the VariControl VC 1E control.
