Fully integrated liquid cooling system : The cooling lubricant is led through eight liquid nozzles which are arranged at the spindle and cools the whole tool evenly from the tip to the shank at all machining stages.
The machine bed of massive aluminium cast facilitates highest stability and a low-vibration operation.
Together with the flexible gaiter at the spindle it furthermore guarantees that all the liquid will remain solely in the working chamber of the machine. The removable liquid drawer under the working chamber also contains a filter mat for separating grinding particles.

Easy workflow : Fixing the three material blocks takes only little time and the two removable changer stations for four tools each will be equipped with just a few moves. The material will then be machined fully automatized and you can spend your time with other useful things until you remove the finished work.

Or you specifically add the wet grinding Premium+ to the already existing machines for dry processing in the dental laboratory. It will save you the cleaning works which become necessary in an alternating operation between wet and dry processing in one machine.

Measurement of axes with calibration specimen. Automatic axis compensation for exact results.
