Dec 02, 2011· 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.

Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools.Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures. As a result, tool steels are suited for use in the shaping of other materials.

The goal of machining tool steel is to produce a tool of the proper shape and the proper dimensions. The tool should also have a smooth surface and a balanced geometry, if possible. Avoid tearing of the surface, as a rough surface finish can lead to initiation of a crack.
Sep 12, 2009· I am working on a project that involves milling tool steel. I work in an architectural metal fabrication shop and know only the basics of milling. I want to be able to make a series of 1/8" through slots in 1/4" thick tool steel and then round the edges.
Run dry, avoid cutting fluid. Trochoidal milling is a suitable method, which enables high table feeds in combination with low cutting forces, generating low cutting edge and workpiece temperatures which are beneficial for productivity, tool life and component tolerances.
When cutting a gummy material such as aluminum or soft stainless steel, coolant will likely be needed to lubricate the tool and let the chip slide up the flute and off of the tool's relief angle. But when machining most mold steels (P20, H13, S7, NAK55, D2), air blow may still be the right choice.
Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material.
