Efficient milling of nanocomposites
Nanocomposites are thermoplastic mixed materials that consist of 50 to 60 percent ceramic filler. With this filler, the stability of the plastic can be significantly increased. This improves its properties as a permanent dental component. Due to the high filler content, nanocomposites are usually machined in powder form and are therefore very abrasive. For this reason, diamond-coated tools DIP®3S or at least hard PVD coatings such as TL5 should always be used.
Depending on the filler and content, we recommend ball or torus milling tools with two or three cutting edges as well as the nanocrystalline diamond coating DIP®3S for milling nanocomposites. This coating effectively prevents processing dust from adhering to the tool. As a result, the tools no longer have to be cleaned periodically and also do not build up increased cutting pressure.
Optimum adjustment to matrix and fiber
The 3D processing of nanocomposites requires cutting geometries that are well suited to processing the plastic matrix. On the other hand, they must also have sufficient abrasion resistance against the fiber-reinforced ceramic. The material-optimized tools from Hufschmied optimally meet these special requirements when milling nanocomposites.
