Narrow slots, long tool life and a favourable cost per cutting edge? With the expansion of its slot broaching system, HORN demonstrates how the shaping process can be used economically in small diameters. For field tests, HORN looked for customers with special components and high quality requirements. A key component of a medical endoscope was ideally suited to this. The contract manufacturer Öschger GmbH from Emmendingen agreed to participate in the long-term tool tests and was impressed by the performance of the new system.
