Products and services

Whirling – Polishing – Milling – Keyseating

Very high levels of surface quality can be achieved with the whirling process. In this process, an eccentrically laid whirling ring circles around the slowly rotating workpiece – in most cases without the use of a coolant. We provide a large selection of whirling machines for both inner and outer whirling.

The drawing process involves creating the groove step by step. A cutter is drawn vertically with a lifting motion along the bore hole in conjunction with a horizontal feed motion. In contrast to slotting or broaching, keyseating provides enormous advantages in terms of economy and flexibility.

We offer three various types of keyseating machines in diverse sizes and these in NC and CNC versions with hydraulic or linear drive.

Polymat 70/100/125 CNC

CNC machines have controlled axes, which allows interpolation of the axes. Accordingly, in addition to the standard feather keyways according to DIN 6885 or custom profiles in through-holes, these machines also cut:
• Oblique keyways
• Oil grooves
• Keyways into blind holes
• Helical keyways
• Regular and irregular multiple-keyways/profiles (serrated/spline/involuteprofiles/...)

In addition to manual indexers, automated indexers (3rd CNC axis) can also be used on these machines.
