2015-6-22 · 2015-6-22 · Milling in hardened steel - a study of tool wear in conventional- and dynamic milling Erik Ersvik & Roj Khalid Milling is a commonly used machining process where a rotating cutter removes material from the workpiece. In recent years, attention has been turned towards so called dynamic milling methods which differ from the conventional way of ...
Hard Milling – How to Machine Hardened Steel. Efficient milling of heat-treated tool steels with indexable carbide tooling. We''re often asked if you can efficiently machine heat-treated tool steels with indexable carbide tooling. The answer is a resounding yes, but successful hard milling requires an approach that''s quite different from ...
2002-9-30 · The end milling of AISI D2 tool steel in the hardened state (58 HRC) gave tool life values of <40 m length of cut. Little difference was found in tool life between the best of the commercial indexable insert tools tested and their solid carbide equivalents.2.
· 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 …
Holemaking & Threading. Designed for threading hardened steels 46-68Rc, this single thread form tool is designed to mill common pitch sizes. The top of its included angle is ground to a flat for increased wear resistance, ensuring that your tool life is maximized. Designed for threading hardened steel 48-68Rc.

2000-5-1 · This paper investigates critical issues related to high-speed five-axis milling of hardened D2 tool steel (hardness HRc. 63).. A forging die cavity was designed to represent the typical features in dies and molds and to simulate several effects resulting from complex tool path generation.
The paper presents an experimental investigation into the slotting of hardened AISI D2 (~62HRC) tool steel using 0.5mm diameter coated (TiAlN) tungsten carbide (WC) end mills. SEM analysis of tool morphology and coating integrity was undertaken on all tools prior to testing. Tool wear details are given based on resulting cutter diameter and slot width reduction.
2016-1-1 · High speed milling is largely utilized to substitute some EDM and polishing operations, mainly in hardened tool steel finishing. Tool path strategy may either enable good surface finish or contributes to generate high roughness values and poor surface finish. Tool inclination (angle between tool axis and workpiece surface) influences the system ...

The milling grade chain for hardened steel includes PVD and CVD carbide grades along with CBN-tipped grades, cermets, and ceramics for various machining conditions. Use the information below to find the right grade for your production.
· Recommedations for milling hardened A2 tool steel. I need to machine some A2 tool steel that is hardened to about RHC50. There are some grooves about .090" deep to be cut with a .125" ball nose end mill and also some large pockets that we will use a 3/8" cutter. Thirdly, there are some drilled and countersunk holes.
The paper presents an experimental investigation into the slotting of hardened AISI D2 (similar to 62HRC) tool steel using 0.5mm diameter coated (TiAlN) tungsten carbide (WC) end mills.
2000-3-1 · In our tool life experiments, inserts with flat rake faces (strongest) performed best. It is important to choose those tools and inserts that were specifically designed for high-speed milling of hardened tool steels. Use Tools with Minimal Flutes. Tools with …
