Grinding Machining Process : Complete Notes - mech4study

The selection of the structure of the grinding wheel can be easily understood by the one simple example. The rough grinding on the soft and ductile material done by only open structure because the work piece is soft and ductile therefore the chip flow will be continuous and rough grinding involves more material removal and more space for the chip removal is required.

GRINDING FOR TOOLMAKING

Grinding low-alloy tool steels seldom presents any difficulties. 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.
