A grinding machine includes means for changing the feed rate of a grinding wheel relative to a workpiece when the grinding wheel approaches the workpiece. The grinding wheel is insulatedly mounted on a wheel slide which is moved by a feed device toward and away from the workpiece. An electrode device is mounted adjacent to the grinding wheel and is connected to an electric …
The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality. The regulating wheel acts like a brake, controlling the rotational speed and thrufeed rate of the workpeice. An angular-topped workrest blade supports the workpiece as it passes through the grinder between the grinding and regulating wheels.

A sharp and open wheel keeps the grinding power low and allowing for high material-removal rates without form loss or workpiece burn. Although this paper only covers the dress speed ratio, it should be known that this is not the only dressing parameter that needs to be considered when setting up or making adjustments to a dress cycle.
Multiply surface speed/min by your radial infeed amount per pass (assuming traverse grinding). If you are only infeeding on one side use half your radial infeed amount. This result would be your specific removal rate or Q'. This rate will be inch² or mm² per minute. Then multiply by your traverse rate to get your MMR.
1) Grinding wheel speed and workpiece speed. 2) Grinding wheel sizes and workpiece sizes. 3) Infeed amount. The above relations are explained by the following figure. D: Diameter of grinding wheel (mm) d: Diameter of workpiece (mm) V: Wheel speed (m/min) v: Workpiece, wheel speed (m/min) f: Feedrate.
Different grain qualities are available to meet various grinding needs. TOP TIP 700A grain is an efficient alternative to 500A, bringing increased productivity on stainless steel grinding applications. 700A has excellent free cutting performance, providing higher material removal rates at lower pressures, generating less heat.

Example 2.5 The width of grinding contact in a horizontal surface grinding machine is 15 mm (or 0.394 in.), the real depth of cut is 10 μm (or 0.000394 in.) and the work speed is 300 mm/s (or 709 in./min). What is the removal rate and what is the specific removal rate?
Most cylindrical grinding machines offer a rather wide range of work rotation speeds, table traverse speeds, feed rates, and, sometimes, different wheel speeds as well. The proper selection of these variables, in combination with the choice of the grinding wheel, has a great bearing on the results and the economy of the grinding operation.
