✦ Synopsis

The factors affecting the grindability of high-speed steel (HSS) were investigated by measuring G-ratio and power consumption in surface grinding of 18 grades of HSS of different composition with an aluminium-oxide wheel. The dominant factor affecting grindability was the size of vanadium carbide. The marked difference between HSS produced by the conventional method and the powder-metallurgy method was analyzed. The relationship between power consumption, G-ratio and grindability was investigated.
