PERFORMANCE CLASS

K5+: Power package with loads of features.

Your top performer in the laboratory for convenient dry processing of blocks and discs.

Visibly different, noticeably better: plus extra power for hard materials.

After its face lift, the K5+, our proven top selling five axis milling machine, has an all-new look. And, as if that wasn’t enough: we added an over 60 % more powerful spindle as well. That means you can always go all out when milling, making it much easier to machine tough materials like cobalt-chrome. Thanks to its proven reliability, the K5+ is a true driver of performance in any laboratory.

Highlights

Power package with lots of features

The K5+ machines a particularly wide range of materials and indications in disc form with a thickness of up to 40 mm. That means it helps make your everyday work easier with lots of innovative technologies. Two particularly useful features are the directdisc Technology for single-handed, tool-free disc fixation, and an integrated ionizer that neutralizes most of the static charge of plastic chips – practically eliminating your cleaning work.
Thanks to its highly stable machine bed structure, made of a solid cast body, the machine generates less vibrations and delivers first-class surface quality.

Keeping it all together

Tools and material blanks are stored in the machine’s practical accessory drawer, so they are always close at hand. An Administrated Tool Board for milling tools is also integrated into the drawer. Its numbered slots are managed using the dentalcam software, creating an active tool pool of a total of 30 tools.

Quick start

Revolutionary technologies such as directdisc Technology for one-handed and tool-free blank clamping and an integrated ionizer, which largely neutralizes the static charge of plastic chips such as PMMA and thus considerably reduces the cleaning effort, help you to achieve this.

CoCr prefab abutments

You can also easily produce prefab abutments made of CoCr and block materials with the right holders.

Discs up to a thickness of 40 mm

The K5+ processes discs up to a thickness of 40 mm. An ionizer neutralizes the charge of plastic chips.
