Principles of Modern Grinding Technology | ScienceDirect

Grinding fluids reduce grinding temperatures in two different ways. The first is by directly cooling the process within the grinding contact area. In creep-feed grinding, direct cooling is a powerful agent for reducing grinding temperatures. The second is by maintaining the wheel cutting efficiency.

Principles of Modern Grinding Technology | ScienceDirect

Real contact area and apparent contact area are both essential to understand how grinding forces and grinding temperatures change during a grinding process. Conformity and real contact area also affect how an abrasive wheel wears in a grinding process. An elastic wheel spreads the grinding force over a larger area and reduces temperature peaks.

Choosing The Right Grinding Wheel | Modern Machine Shop

Dec 15, 2000· The first consideration is the material to be ground. This determines the kind of abrasive you will need in the wheel. For example, aluminum oxide or zirconia alumina should be used for grinding steels and steel alloys. For grinding cast iron, non-ferrous metals and non-metallic materials, select a silicon carbide abrasive.

Metallographic Abrasive Grinding

Grinding/polishing pressure is dependent upon the applied force (pounds or Newtons) and the area of the specimen and mounting material. Pressure is defined as the Force/Area (psi, N/m 2 or Pa). For specimens significantly harder than the mounting compound, pressure is better defined as the force divided by the specimen surface area.
