Factors which can affect the grinding wheel speed

Grinding has a long history, with the emergence of a large number of fresh material and application has brought an unprecedented breakthrough for the future of the show. Diamond grinding process is a more complex process, multivariable interaction process, always changing them, diamond grinding wheel is removed quantitative workpiece material to obtain a higher surface quality and precision.

Wheel speed on the line is more complex when the wheel was increased from 28.8m / s to 33.6m / s when the speed increased only 16%, while the blocked amount increased threefold. Because of the increased wheel speed of the abrasive grains of the maximum depth of cut is reduced, chip cross-sectional area decreases, while the number of cutting and grinding heat increased so that clogging increases. But when high wheel speed to a certain extent (eg reach 50 m / s or more), the amount of clogging wheel but declined significantly. So choose the best to avoid wheel speed 20m / s to 50m / s this speed grinding.

Practice has proved that diamond grinding wheel speed to prepare, wheel loading increased threefold, so the higher the speed of the workpiece, abrasive load rain, abrasive cut more shallow depth, the cutting cross-sectional area decreases, while grinding thickness increases, heavier abrasive passivation, increase the grinding wheel on the workpiece extruded layer, a diamond wheel corresponds to harden characteristic change occurs, thus resulting in the clogging of the grinding wheel.

Wheel size, hardness, structure and wheel speed grinding methods to optimize the grinding process to establish a reasonable grinding parameters and summed up the law, it is an effective way to guide the production, but also grinding technology research should focus on the content.
