The aim was to develop a machine that masters all materials and at the same time takes over small milling operations on the turned part in order to avoid a second clamping on another machine. At the same time, it should be very stable and highly accurate. Today, the machine can be used both as a supplementary machine in any contract production. However, it is also found in series production.

Machine concept

On the one hand, the sloping bed concept used ensures optimum chip fall. Combined with the integrated flat guides in all main linear axes, maximum stability is guaranteed.

In this case, cast steel is used as a homogeneous building material in order to ensure uniform thermal behaviour. Today, one often hears of so-called mineral casting. This should be thermally even better than cast steel. But is it really? In this case, however, it is repeatedly “concealed” that you then have to screw linear guides made of steel onto this mineral casting (synthetic resin + concrete). I.e. two materials with two different expansion coefficients collide. Tensions arise between the two materials. The expansion advantage is thus eliminated.

Then why is mineral casting still used? The answer is in the price! The production costs are only ¼ as high as in the case of cast steel. Do you get this price advantage from the machine manufacturers, or does the shareholder get this price advantage?
POS relies on cast steel for technical reasons in order to be technically optimally positioned.

A German quality turret with 12 driven tools and integrated collision protection ensures high flexibility and maximum safety for complex orders.

Turning with full equipment

Interior space

Through the arrangement of the fenders needed by the inclined bed, chips are carried away in a uniform and concentrated manner into the chip conveyor. The operator always has an optimal ergonomic state to the process. Cleaning is also reduced to a minimum thanks to the integrated rinse. Of course, proper illumination takes place, so that shadows are reduced in order to increase process reliability.


Full equipment is the motto at POS. The large IKZ system, glass scales, etc. or the small things like the electronic handwheel, the water gun, air on the table or air through the spindle. It’s just everything you need, always with you. Thus, the purchase does not become a gauntlet with the fear of being able to forget something that can no longer be retrofitted later, or only with a lot of money. Not from POS, here you are safe for your order of tomorrow.


This machine has also been prepared for automation since the very beginning. Whether preparing for a bar loader or preparing for an automatic parts catcher, the conviction of being ready for automation is demonstrated at all times. The POSturn E 450 is also prepared for all types of automation and has been installed in the market many times.
