Designed for todayʼs hard machining challenges, Carmexʼs CMT line delivers long tool life, high material removal, excellent surface finish, reduced cycle times and lower cutting forces in materials up to 62 HRc steel. Constructed of MT8 sub-micron carbide grade with advanced PVD triple coating, the CMT line is available in configurations for threading, grooving and chamfering. The specially ground profile incorporating four to eight cutting edges and spiral flute design offers high heat resistance and smooth operation in all general-purpose applications, the company says.
The cutters can be used with existing CMT C18 type toolholders, but offer improved performance thanks to the carbide grade, the PVD triple coating, and the spiral flute design for smoother cutting, the company says. Available in a range of profiles, including 60 degrees and 55 degrees partial profile for internal and external threading, and ISO and UN full profile for internal threading, the company also offers multiple sizes for chamfering, grooving and boring, as well as regular and full radius groove milling.
Editor PickCan 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.
