Automotive component manufacturers have to guarantee consistently high machining accuracy in large batches. ZBG Zerspanungstechnik Bruck GmbH in Bruck, Oberpfalz, Germany, achieves this with the aid of the NC4 laser tool setting system from Renishaw. With this system, the machining centre checks cutting tools for wear or damage, and also determines their length to compensate automatically for any possible thermal growth of the machines in operation.
