Flywheel Brake

The flywheel brake design on theMinster PM4 gives the operator the ability to quickly slow the flywheel to a pre-set speed. The combination of an increased brake contact area, reduced surface contact pressure, and increased useable lining thickness provides 7 to 10 times the life of a normal brake lining.

Dynamic Balancing

The Dynamic Balancing System on the PM4 greatly reduces the effect of the slide inertia forces caused by running at high speeds. This reciprocating balancer helps maintain precise slide bottom-dead-center repeatability resulting in less die wear and greater part accuracy. It also allows the press to run at higher speeds and reduces press vibration.
