Looks Compact
But works packed
5X-300 Series

Amazing grinding capability

With the adoption of a high RPM spindle,
5X-300 boasts its unsurpassed capability of grinding
Lithium Di-silicate (Glass Ceramic).
We improved user convenience by applying the cartridge
that can mount and mill up to 6 CAD Blocks
(Lithium Di-silicate, Nano-composite),
and the high-precision ball screws allows you
to get high-quality milling outputs.


The beginning of a small change

With a small change of ‘7° Tilted Door’ to ensure the user’s viewing angle,
you can clearly see the milling progress. With the door opening wide, you can secure enough workspace to conveniently change materials and setting tools.
In addition, the interior floor is inclined to convenient cleaning.

Device to automatically
exchange 12 tools

With a 12-tool pocket, you can mill almost every material
such as Zirconia, Lithium Disilicate, PMMA, PEEK, and WAX in just one setting,
and the automatic tool change function allows you to use equipment without interruption.



Like natural teeth

Every patient wants a prosthesis that looks natural.
With milling the grooved part precisely
using ARUM’s 0.3 mm tool for Zirconium,
you can reproduce the teeth that look natural.
