R5 Dental Mill 

High-end dental restorations with the speed and efficiency of automation

The VHF R5 5-axis dental mill is an automated solution for wet and dry milling designed to tackle a range of dental applications with reliability and precision. With an impressive 150 kg of weight on a minimal footprint and a repetition accuracy of the linear axes of ±0.003 mm the VHF R5 delivers ultra HD accuracy in a space that works for your lab.

Unrivaled Wet & Dry Machining

Whether you are a dental clinic or lab, with the R5 from VHF Germany, you can simply process everything, 24 hours a day. R5 is a 5-axis system, designed and engineered to be fast and effortlessly between wet and dry machining. Thanks to the DirectClean™ Technology*, the R5 cleans and dries itself between jobs due to a groundbreaking package that includes an ionizer, self-cleaning and built-in dryer. Moreover, the unique material loading with DirectDisc™ Technology* of the changer with up to ten discs saves you valuable time.

Key Highlights

Maximum automation

R5 can process without interruption up to 10 discs or 60 blocks or abutments. With a tenfold blank changer for wet and dry milling and grinding, the R5 brings revolutionary approaches to the production of dental prostheses. The R5 disc changer is a robot arm with a pneumatic gripper for swift changing. The removable tool magazine holds 16 tools and the tool changer does not require user intervention.


Utmost accuracy

The R5 with linear axes X-/Y-/Z-axis swivels the high-frequency spindle (B axis) by up to ±35°, therefore the workpiece holder only needs one moving axis (A axis). This makes the entire system gain stability and have the lowest vibration operation. The repetition of the linear axes of ±0.003 mm ensures a unique precision in ultra HD.

Powerful and Robust

R5, with 800 watts of power and 80,000 RPM, is entirely engineered and manufactured in Germany for higher dental lab productivity with proven industrial quality.

It mills the toughest materials on the market including titanium (Ti) and cobalt-chrome (CoCr).


Game-Changing Technology

Thanks to the DirectClean™ Technology, the R5 is equipped with an ionizer that reduces the static charge from human agents, self-cleaning, and a built-in dryer making it extremely easy to maintain and operate, thus saving significant labour time.




  • High-speed spindle & superfast milling strategies for restorations in no-time
  • Wide range of materials that are easy to load
  • R5 has the ability to drill screw access channels so that you don’t have to keep a double inventory of regular and pre-milled blocks
  • R5 grinds and mills with clear water, no additives needed (except for titanium)
