"We only need about thirteen seconds to produce a thread," says Ben Broekhuis. He is responsible for the metalcutting pro- cesses in the company Vremac, Apeldoorn, in the Dutch province of Gelderland. The company is a specialist in the development and production of hydraulic cylinders. For machining an external thread on a cylinder, Vremac switched to a special milling system from Paul Horn GmbH. The result: approximately three times faster production than previously and a considerable increase in tool life as well as process reliability for unmanned production.
