GRINDING FOR TOOLMAKING
When grinding high-alloy tool and high-speed steels with high carbide content, however, problems can easily occur. For this reason, the grinding parameters must be selected carefully. The higher the wear resistance of a steel, the more difficult it is to grind. The wear resistance of a material is determined
Characterization and formation mechanisms of rail chips ...
The high speed grinding is different from the facing and peripheral grinding. During the high speed grinding, the rail is ground by the side face of the grinding wheel which is not powered. There is an angle between the axle of the grinding wheel and the rail cross section, so that a lateral grinding force was produced when the wheel rolling ...

The right choice of the feed and cutting speed, as well as the grinding wheel specification, is relevant to a ductile grinding (Yasui, 2007). Smaller chip thicknesses, resulting from an increase of the cutting speed, lead to a decrease of the process forces, surface roughness, as well as dimensional and form errors ( Kopac and Krajnik, 2006 ).
Grinding Wheel: A Definite Guide For You (With PDF)
A tapered Grinding wheel is a straight wheel that tapers externally towards the midpoint of the wheel. As this pact is stronger than straight wheels, it accepts advanced lateral loads. The straight wheel with a tapered face is chiefly used for gear teeth, grinding threads, etc. Straight cup Grinding wheels:
Machining 101: What is Grinding? | Modern Machine Shop
Work speed defines the speed at which a grinding wheel passes over a workpiece or rotates around a center. High work speeds lower the heat retention and reduce the risk of thermal damage. Both high work speeds and reducing the diameter of the wheel result in increased grain depth of cut, performing like a softer grade wheel.
