The manufacturing of solid-carbide and PCD rotary tooling has improved markedly, and high-tech grinders have played an important role in this evolution. Circular and band saws have followed a similar evolution. In this this podcast,  Editor in Chief Alan Rooks talks with Shannon Fox, North American sales manager for Vollmer of America Corp., a builder of tool grinding machines, and Dr. Roland Loroch, managing director of Loroch GmbH, a business unit of Vollmer that is focused on re-sharpening and measuring circular and band saws. The discussion focuses on how rotary tool grinding machines are creating more complex, tighter-tolerance tools, and new demands on circular and band saw blades.
