High dynamic turning with FreeTurn tooling

IN September 2019, Ceratizit launched the first standard range of products for its High Dynamic Turning with FreeTurn process. The tool manufacturer has taken the next step, being joined by machine tool and control system manufacturers as well as providers of CAD/CAM systems. The new turning technology, combined with the company’s dynamic FreeTurn tooling, means that it is now possible to carry out traditional turning operations such as roughing, finishing, contour turning, face turning and longitudinal turning with just one tool. Despite new cutting materials, chip breakers and tooling systems being invented to optimise turning, the basic turning process itself has remained essentially unchanged for many years: a contour is created with an indexable insert at a fixed angle to the workpiece. This method has not changed, even with the addition of controllable axes in modern turning-milling centres. Ceratizit has taken advantage of the features of these turning-milling centres and developed the High Dynamic Turning system (HDT). The tool approach and point of contact in the machine can be varied, as opposed to conventional turning with a fixed tool.

❍ One indexable insert with several cutting edges

The milling spindle is used to produce the corresponding approach angle to the workpiece. The use of the spindle drive in conjunction with the slim, axial tool design of the FreeTurn tools creates 360° of freedom 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. The angle of approach is freely variable at any time and can even be changed while cutting. Ceratizit SA www.ceratizit.com Ceratizit USA, Inc www.ceratizit.com
