Hard turning

Hard turning enables the machining of materials with a hardness of up to 64 HRc. Thanks to hard turning laths, you need fewer process steps and thus increase the productivity of your manufacturing process. For example, grinding can be replaced by hard turning on Benzinger's specifically constructed hard turning machines.

Replacing grinding with hard turning has already proven its worth in numerous applications.

Hard turning proves to be particularly advantageous.
Due to the fact that hard turning reduces investment and operating costs by eliminating the need for costly grinding machines. Throughput times are shorter with hard turning. Components are finished on only one machine in one process.
Hard-turned components are often more accurate than ground ones because there are no shape errors due to incorrectly profiled grinding wheels. In hard turning, the shape accuracy depends solely on the NC axes of the lathe. In addition, hard turning is more flexible.

It is possible to machine any contours that cannot be achieved by form grinding due to grinding wheel profiles that cannot be dressed. In addition, hard turning usually involves dry machining. This hard turning method eliminates the need for costly cleaning and drying of the finished workpieces.
In hard turning, the surface quality can also be optimized with the aid of the technology parameters cutting speed and feed rate. In this way, hard turning can also achieve mirror-smooth surfaces of less than 2 to 3µm in shape on curved and profiled workpiece contours.
