The all-rounder for blocks

E4 can wet grind glass ceramics or composites with ceramic content and dry mill materials such as zirconia and PMMA. In addition, you can benefit from easy switching by inserting the tank for wet processing or the optional container for machining dust to start processing high-quality restorations. A special filter mat in the liquid tank ensures the tank is chippings-free.



Compressed-air free operation

Like the E5 model, E4 does not use compressed air. There’s no need for an external compressed air connection or integrated compressor, thanks to vhf’s patent-pending AIRTOOL. Its turbine blades use the speed of the high-frequency spindle to generate a powerful airflow, which keeps the workpiece free from dust and chippings. They are removed by vacuum from a dust collector.

Wet Grinding

PUREWATER Technology ensures that the closed liquid circuit in the machine requires no grinding additives. This translates into easy disposal and even lower running costs.


Proto3000_Dry milling icon

Dry Milling

The optional dry container allows you to mill materials such as zirconia, PMMA and various composites with your E4 without cooling water or compressed air.
