New milling grade boosts productivity

Often described as difficult to machine, these materials pose challenges to those involved in their machining, with particular emphasis on process security and tool life.

The new CTCS245 grade complements the existing CTPM245 and CTC5240 grades from Cutting Solutions by Ceratizit by enhancing performance on materials, such as Inconel, Nimonic and Rene, making it the ‘go to’ grade for aerospace applications.

For example, when machining Nimonic 80A material, which is commonly used in turbine blades, 12mm button inserts were run at 45m/min at 0.25mm/tooth feed and 2mm depth of cut. The tool life increased by 100% from 62 minutes to 124 minutes compared to using Ceratizit’s older CTC5235 grade. When used on Inconel 625, the gains were even greater, with tool life increasing 200%, even when the cutter was run at 38% higher cutting data than the competitor’s grade.
