The company’s line of milling tools features cutting geometries and coatings engineered specifically for dental applications. The line consists of solid carbide ballnose and torus end mills, which are designed for machining zirconium oxide, PMMA, wax, cobalt chrome and titanium. Both types of cutters feature a radius tolerance of ±0.005 mm and diameter tolerance of 0.01 mm. Solid carbide ballnose end mills are suited for roughing and finishing, and their optimized geometry provides stability in long-reach applications. The tapered-neck ballnose end mills provide rigidity against deflection and are suited for finishing and rest material machining. Torus end mills are available with two or four flutes for roughing in cobalt chrome.
The end mills are available with a variety of coatings including TiAlN, which protects the tool from premature wear when machining non-precious metal alloys; CrN, which prevents the material from sticking to the cutting edge of the tool when milling PMMA and wax; and a diamond coating, which ensures increased tool life when machining zirconium oxide.
Can Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
