Ceratizit’s HDT System Offers 360-Degree Turning

Ceratizit’s High Dynamic Turning (HDT) System, in combination with the company’s FreeTurn standard range tooling, enables traditional turning operations (such as roughing, finishing, contour turning, face turning and longitudinal turning) with just one tool. The tool approach and point of contact in the machine can be varied as opposed to conventional turning which utilizes a fixed tool.

According to the company, the HDT milling spindle offers 360 degrees of movement. Instead of a statically positioned insert in the holder, the milling spindle is used to produce a corresponding approach angle to the workpiece. The use of the spindle drive — in conjunction with the slim, axial tool design of the Ceratzit FreeTurn tools — creates flexible 360-degree movements without the risk of collision. Due to the rotation around its own tool axis, the cutting edge change can be done without interrupting the cutting process. Also, the angle of approach is freely variable at any time and can even be changed while cutting. This enables flexible machining of almost every workpiece contour as well as optimum chip breaking, higher feed rates and an increased tool life. Depending on the machine capabilities, the technology can be used functionally in all areas of turning operations. The approach of the milling spindle on the Y and Z axes on turning milling centers is widespread, thus enabling cutting from above and below. Depending on the machining area and workpiece size, this flexibility can be an important factor in production.
