Nexen MBU on a Rotary Cutter

Problem

A plywood manufacturer was suffering loss of product due to timing problems on the rotary cutter. In the final stages of production, decorative paper is placed on the plywood. The paper is cut between each sheet of plywood using the rotary cutter. The Shinko electro-magnetic clutch-brake being used for timing on the cutter was inaccurate, resulting in cutting of plywood. The clutch-brake product life was short (6 months), further increasing production cost.

Solution

Nexen suggested the MBU air clutch-brake to replace Shinko and increased the accuracy from 25mm to 15mm. Maintenance costs are minimal as only the friction plate needs replacement and the product has a 3-5 year life.
