Ceratizit says that its new ProACT-Mill UNImax solid-carbide milling cutter is not only powerful and universally applicable, but also environmentally friendly thanks to the resource-efficient manufacturing process of the upGRADE CT-GS20Y grade, part of a particularly sustainable carbide family which the company calls upGRADE.

“What’s special about upGRADE CT-GS20Y is the significantly smaller carbon footprint generated during production compared with carbides from conventional production,” explains Michael Wucher, global technical product manager. “We achieve this using 99% reprocessed cutting tools as the raw material.”

The test results of the new series underline its potential: Ceratizit says that ProACT-Mill milling cutters deliver up to 30% higher performance compared with other universal tools. The newly developed coating, which brings with it additional performance and tool life reserves, further contributes to this level of performance.

A variable helix pitch ensures extremely quiet running and optimum chip removal. The ProACT-Mill UNI has an HB shank for optimal force transmission, while the reinforced tool core ensures even force distribution throughout the milling process.

To ensure stability of the cutting edge, the mill features a radial clearance face. The face-finishing chamfer promises top surface quality with base machining, while cutting edges with an irregular pitch specifically suppress vibration. Ramping milling and helical milling are possible up to an angle of 30°.

The ProACT-Mill UNI with a cutting edge length of 3xDC is particularly suitable for series production and trochoidal machining. Chip breakers in a radial design deliver long tool life and break the chips to a length of 1xD, with even and consistent removal thanks to the special shape of the chip space.

When it comes to maximum material removal rates, the ProACT-Mill UNImax offers special geometry design for depths-of-cut of up to 2xDC.
