Ceratizit SA hopes to change the turning process
Company's High Dynamic Turning and FreeTurn tools promise full range of motion.
The past century certainly has seen a variety of developments with turning. Some, including new substrates and chipbreakers, have fine-tuned the process, making it more effective. But overall, turning has remained basically the same. Even indexable inserts used for contouring are set at fixed angles. The inserts have remained static.
Ceratizit SA, Mamer, Luxembourg, hopes to change the turning process altogether with High Dynamic Turning and FreeTurn tools.
The goal is to move from static positioning of the spindle and inserts to a more dynamic position that allows a full range of motion, said Lothar Schmid, innovation manager at Ceratizit’s Innovation Center in Reutte, Austria.
“HDT is the machining concept that uses FreeTurn tools in application,” he said.

Central to HDT is the idea that the spindle essentially can have 360° of freedom. Ceratizit states that this flexibility comes without risk of collision. Also, the approach, or lead, angle can be adjusted during cutting, an especially useful feature when contouring.
The tool body is stable when combining its slender shank and the rotational freedom. The FreeTurn insert attaches by screw and has multiple cutting edges with different properties, including various angles, corner radii and chipbreakers.
