The new Power Mill solid carbid endmills from Haimer are made from fine grain carbide and are equipped with the company’s pull out protection system, Safe-Lock, which has become a standard for HSC and HPC machining. Endmill geometries are based on an unequal flute and helix design for chatter free high end machining. All tools are coated with latest PVD technology and have an extremely smooth surface for the best possible chip evacuation.
The Power Mill range, with cutting diameters available from 2 to 20 mm, will be made available with 3, 4 and 5 cutting edges having multiple lengths of cut. To offer maximum flexibility to address customers application requirements, different cutting edge solutions (sharp, chamfer and radius) will be offered. Also a roughing geometry with a cord profile will be part of the portfolio.
A typical specialty is the high precision of the tools. All endmills are fine balanced and have a run-out of 5 μm. All shanks are based on the h5 tolerance.
With the launch of the new Power Mill range Haimer has expanded the Safe-Lock offering. Resulting from the wide spread and multiple customer requests for different application areas, Safe-LockTM will be available starting from shank diameter 6 mm.
The Safe-LockTM shanks can be clamped in standard shrink fit and collet chucks without any problems. In comparison, it now doesn’t make sense to clamp μm precision high performance geometries with weldon shanks and push them extremely out of center while introducing extreme unbalance. HAIMER target is to have high availability and replace the Weldon system in the next 10 years. Whereas Safe-LockTM not only supports roughing applications, but becomes a new universal solution that continues to find more and more use during HSC applications with high helix endmills.
