Hard Milling By The Numbers - Modern Machine Shop

Milling heat resistant superalloys (HRSA) Heat resistant super alloys (HRSA) fall into three material groups; nickel-based, iron-based and cobalt-based alloys. Titanium can be pure or alloyed. The machinability of both HRSA and titanium is poor, especially in the aged condition, requiring particular demands on the cutting tools.

Requirements for milling hardened steels - Practical Machinist

Tough Tools. When milling materials from 50 to 60 HRC, not just any cutter will do. Not only is the workpiece very hard, but to reduce thermal fluctuations on the cutting tool, machining is typically done dry. For this, you need tough tools. One company offering such tools is SGS Tool Co., Munroe Falls, Ohio.

Inserts For Difficult Materials - Modern Machine Shop

When milling such materials, coated carbide inserts suffer rapid flank wear, and their primary cutting edges wear flat. Extra-hard particles within the microstructure create "microchatter" that accelerates insert wear. Carbide inserts can also fracture under the shear pressure of machining the hard stock.

Requirements for milling hardened steels - Practical Machinist

In general, hard milling involves cutting primarily tool steel or precipitation hardening stainless steel, such as 15-5 or 17-4, that has been hardened to at least 50 HRC. After a workpiece is roughed in the soft state, it is sent to the furnace for hardening and then finish machined with coated carbide, ceramic or PCBN tools.
