1.Overview
Extremely accurate, high speed cuts (15 cuts per minute, with 21-degree cuts and a width of 200 mm) are made possible by applying a highly reliable AC servomotor and highly accurate ball screw to the shear cutter developed through Nakata Engineering’s cutting-edge technology and many years of experience. Through the use of an AC servomotor and high-accuracy ball screw in the joint apparatus as well, and the inclusion of a double zipper unit, this cutter is capable of high-speed, wide (up to 400mm) steel breaker cuts and joints. In addition to steel breakers, Nakata is also designing and producing auto joint and steel ply cutters, and supplying numerous cutters to the tire industry.
