Your top performer in the laboratory for dry processing of blocks and discs.
The K5 from the vhf PERFORMANCE CLASS is our classic in the field of five-axis dry milling. It has become indispensable in dental laboratories, especially in the field of demanding zirconia processing.
With the K5, you get a highly reliable machine that will mill your demanding laboratory work to a high quality.
The K5 impresses above all with its rock-solid construction with a solid cast body, the large rotation range of its B-axis of up to ± 35 degrees and the ability to process discs with a thickness of up to 40 mm. For you, this not only means first-class machining quality, but also a great variety of indications.
The machine’s practical accessory drawer keeps tools and material blanks neatly organized and ready to hand. An Administrated Tool Board for milling tools, which is actively managed via the dentalcam software, is also integrated into the drawer.
The K5 fixes discs up to 40 mm thick: you benefit from the greatest possible variety of indications. And with the corresponding holders, you can also fabricate block materials and prefab abutments from CoCr.
vhf has been using high-quality 4-fold hybrid ceramic bearings for over ten years, particularly for machining metals. For you, this means a significantly longer spindle service life, higher surface quality and noticeably better accuracy of fit.
