K3 | K4 Impression

The perfect introduction to digital manufacturing


Dear end customers,
our dental milling machines and dental grinding machines are exclusively sold via OEM partners and specialised trade. If you are interested, please directly contact our sales partners.


  • Most obvious is the extremely compact design of the K3 Impression and 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.



  • 4 simultaneously working axes

  • The integrated HarmonicDrive® rotary axes (A axis) has a rotary range of 360 degrees.


  • 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.


  • 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. Also available without automatic tool changer as K3 – the cheapest vhf machine. Thanks to a convenient quick chucking device the tools can be exchanged also by hand within seconds.


  • 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.


  • no previous knowledge necessary

  • Very easy operation via provided CAM software DentalCAM with Direct-Mill function – no previous knowledge in milling necessary.
