Ultra high productivity for
nickel based heat resistant alloys

From difficult-to-cut to easy-to-cut! Generation of cutting heat

Feature of Ni based heat-resistant alloy

Feature of Ni based heat-resistant alloy

Ni based difficult-to-cut heat resistant alloys such as Inconel 718 soften at temperatures exceeding 800ºC. At these temperatures, difficult-to-cut materials become easier to machine because heir bearing and tensile strengths are lowered.
Ceramic end mills can work effectively at these high temperatures and self generate the heat required to soften the machined material through ultra-high feeds and speeds.

High temperature hardness of cemented carbide and ceramic

High temperature hardness of cemented carbide and ceramic

Cemented carbide end mills are significantly
reduced in strength when exceeding 800 degrees.
However, the strength of ceramic end mills is not
affected and therefore can be used at the high
speeds and depths of cut required to generate
sufficient heat to enable machining.
