HPC and HSC –
a step into new dimensions
Our engineers will identify the potential for cost reductions in your production which can be achieved through High-Performance Cutting (HPC – increasing material removal rate) or High-Speed Cutting (HSC – high machining speeds). These modern technologies make full use of the entire high-performance capabilities of our SPK cutting materials. Our comprehensive engineering services guide you along this path.

Selection of cutting material – is especially important with such a wide range of different cutting materials, including SPK cutting ceramics, SPK-WURBON® and Cermets, characterized by particular strengths of the individual grades.
Tool design – for implementation of individually optimized tools. Multi-insert tools can carry out various machining operations without time-consuming tool-changing. Machining time per part falls dramatically. Tool design is supported by specialized CAD-CAM systems to ensure optimum results all the way from the tool design to its production. This method brings us in a position to offer our customers customized tools at a fair price.
Processing plans – here, too, you can expect highly sophisticated solutions for your machining tasks.
Workshops and training sessions – share our know-how.
Process optimization – because we want you to get the best possible out of our high-performance cutting materials, not only in terms of cutting speed, feed rate, workpiece accuracy and tool-life but also in terms of optimum surface finish and maximum productivity.
Shortening process chains – as important as never before
This is a way in which added value can be maximized according to the principle
of “less is more.” Examples how you can shorten your process chains
with our products and technology are:
- integration of a number of machining operations in a single tool with the positive effects already described and
- substitution of complex and costly machining methods. Thus, for example, by combining hard turning and grinding the costly coarse grinding can be replaced by hard turning. When using hard turning instead of grinding, tolerance classes IT5 and surface qualities in the Rz = 2–6 µm can be achieved. That means that grinding can be dropped as a final machining step.
