High Speed Steel Cutting Tools Operate At Cutting Speed

Hss tools have a harness of 62 64 rc.

High speed steel cutting tools operate at cutting speed.

Crucible steel was awarded a patent for the first recognized high speed steel in 1910. Metal removal rates are faster today than ever before. High speed steel is a high carbon tool steel containing a large dose of tungsten. Hss high speed steels still playing a very significant role in metal cutting.

These include better and more capable machine tools and cnc processors that allow the machine to accurately cut at increasingly higher speeds and feeds. Many factors are driving shops to faster metal cutting rates. What was considered high speed machining just a few years ago is regarded as conventional today. 18 tungsten 4 chromium 1 vanadium 0 7 carbon and the rest iron.

A typical hss composition is. 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. All cutting tools have a recommended cutting speed for any given material. High speed steel hss or hs is a subset of tool steels commonly used as cutting tool material.

So too can carbide and ceramic cutting tools achieve higher speeds regardless of the workpiece material than do ones made of high speed.
