Rotary Axes

Rotary axis type L
Rotary axis type L with three-jaw chuck, mounted in the rear clamping range of a Premium system.

Using a rotary axis, you can process your workpieces from all sides. So it becomes possible to produce complex three-dimensional objects. The axis can be moved steplessly which means a real four-axis machining. For this kind of machining, you just need an appropriate CAM software, as all vhf milling machines are already well prepared with their controllers.

This sort of rotary axis is available in three different sizes:

Rotary axis type S
small size and affordable price

Rotary axis type L
medium size and medium precision

Rotary axis type XL
largest type and highest precision

Each rotary axis can be either implemented with or without a tailstock unit. A tailstock unit with centre sleeve is necessary when you have to process longer objects which cannot be held only with the jaw chuck of the rotary axis, but need additional support on the other side by the centre sleeve.

The tailstock unit is positionable on sliding rails or a hole plate and can be adjusted with a setting screw exactly to the length of your workpiece.

If you need a very high machining precision, we recommend to use the rotary axis type XL. Considering the great number of possible implementations, we would like to ask you for your typical workpiece dimensions which you have to process with the rotary axis. So we can offer you an individual solution.
