Development of a copy-peeling machine for machining the surface of hot rolled square billets

A copy-peeling system to replace the high-pressure grinding method, especially for stainless steel qualities, was developed. The copy-peeling process for square billets was accomplished on an existing planing machine with special test attachments as well as on a specially developed copy-peeling machine. The attainable material removals and the tool life reached during the tests with stainless steel are not sufficient to offer an economic and technically advanced alternative to high-pressure grinding. The advantages of copy peeling with respect to safety and health of the operational personnel are obvious. However, it cannot be expected that this process will be applied extensively.
