High Speed Steel Cutting Tools Operate At Cutting Speed

Metal removal rates are faster today than ever before.

High speed steel cutting tools operate at cutting speed.

Softer metals like aluminum and mild steel have higher cutting speeds than do nasty metals like titanium or inconel. High speed steel hss was developed in the second half of the nineteenth century. High speed steel is a high carbon tool steel containing a large dose of tungsten. Hss tools have a harness of 62 64 rc.

Crucible steel was awarded a patent for the first recognized high speed steel in 1910. So too can carbide and ceramic cutting tools achieve higher speeds regardless of the workpiece material than do ones made of high speed. A typical hss composition is. 18 tungsten 4 chromium 1 vanadium 0 7 carbon and the rest iron.

These include better and more capable machine tools and cnc processors that allow the machine to accurately cut at increasingly higher speeds and feeds. It is often used in power saw blades and drill bits it is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper hardness this property allows hss to cut faster than high carbon steel hence the name. Hss high speed steels still playing a very significant role in metal cutting. High speed steel hss or hs is a subset of tool steels commonly used as cutting tool material.

What was considered high speed machining just a few years ago is regarded as conventional today.
