A new, highly effective tooling option is now available to machinists tackling hardened steels in the 48-65 HRc range from NS Tool, according to Single Source Technologies. The MSBH230 and MRBH230 2-flute micro grain carbide ball endmills are designed to improve chip removal and reduce chatter in hardened steel, thanks to a new design and a new premium Mugen coating.
"Hardmilling molds, dies, punches, and even production parts is becoming more and more popular in North America," said Doug Kline, national sales & general manager of the Consumables and Tooling Group at Single Source Technologies (SST). "We're finding that manufacturers need more options for tooling, especially to fight chatter and increase feedrates. These new tools from NS Tool have been proven to provide these benefits and more."
The new tooling is available in 0.05-3mm radiuses, and in a long-neck (MRBH230) and standard (MSBH230) version.
The new coating from NS Tools has been designed for extended machining of hardened steels. It is hardened to 3600HV and has a high oxidation temperature of 1,300 degrees Celsius, compared to 2800HV for TiAlN and 800 degrees Celsius oxidation, 3000HV and 500 degrees Celsius oxidation for TiCN, and 2200HV and 600 degrees Celsius oxidation for TiN.
In addition to the new coating, the design of the tool has been optimized. A stronger, spiral shape was designed to keep the tool sharper and reduce the machining load. The result of this is significant chatter suppression, reduced deflection, and an increased chip load.
"It's clear that in typical hardened steel applications, this new tool is far superior to other options available," said Kline. "In our test cuts, we've been very impressed with its performance, durability, and ease of use. We're proud to offer it to our customers as a tooling solution for hardmilling applications."
