Ceratizit A new twist on turning
Freeturn tools from Ceratizit uniquely perform all-in-one turning operations using just one tool, resulting in a 25 % reduction in machining time.
Contrasted with conventional turning processes, where a separate tool is required for every contour, a single freeturn tool can complete all roughing, finishing, contour turning, facing, and longitudinal turning operations at different approach angles.
Freeturn tools, combined with Ceratizit High Dynamic Turning (HDT), use the milling spindle to perform the turning process. The freeturn cutting edge can be changed through rotation about the tool axis, allowing machining from all sides and providing significant savings on tools and changeover times, the company explains. The approach angle can be adjusted during machining, which not only enables dynamic machining of almost any part contour in all directions, but also results in adjustable feed rates and perfect chip control.
Unlike conventional turning, the freeturn directs the cutting force through the tool into the spindle and not into the holder. This ensures optimised force distribution and reduced downtime. With freeturn tools, manufacturers can expect 40 % higher feed rate values, up to 90 % fewer empty tool paths, and improved surface quality, Ceratizit states.
The freeturn tool features a screw-on indexable insert and a slim shank for machining in narrow workpiece contours. The freeturn indexable insert can consist of several cutting edges with different properties. Individual approach angles, corner radii, chip breakers, coatings and cutting materials can be combined on a single insert as required.
