VHF K4 Edition - Dry Machining

The perfect introduction to digital manufacturing

Most obvious is the extremely compact design of the  K4 Impression. Upon closer examination, the uncompromisingly rigid construction of the machines leaps to the eye. So it is ensured that you will achieve first-class results – even in extremely hard non-precious alloys on cobalt-chrome basis. High-class drive and measuring units are also essential for producing perfect objects. Here, vhf relies for instance on integrated Harmonic Drive rotary axes.


Highest accuracy

The automatic axis measurement and compensation ensure a consistently high machining precision – and thus top-quality results.

Automatic changer for 6 tools

With K4 Impression you get an automatic tool changer with six stations which enables a complete machining of the workpiece without manual intervention of the operator. 

Worldwide applicable

Due to far range switching mode power supply for 100 – 240 V and 50/60 Hz with country-specific mains plug. Certification according to ANSI/UL61010-1 for exports to the USA and Canada.

Sophisticated protective mechanisms

Protection of the danger zone during the machining process with an automatic safety interlock at the front cover. Protection of the mechanics against dust and chippings as well as reduced wearing and maintenance effort due to integrated working chamber sealing air concept. 

Wide range of materials and indications

Machining of plastics, wax, zirconium oxide and composites up to non-precious alloys on cobalt-chrome basis. For crowns, bridges (also fully anatomical), inlays, onlays, abutments, etc.
