It is different from the traditional integrated super high-speed grinding wheel, the centrifugal force has greater impact on segmented grinding wheel in super high-speed rotation. In this paper, in order to ensure the safety of super high-speed grinding wheel, models for the connection between inner micro-unit’s displacement and stress of wheel matrix were established to optimize high-speed grinding wheel section form, reduce the centrifugal stress and control the radial displacement of grinding wheel. Consider the structural and mechanical characteristics of wheel matrix, strength check of the theoretical formula were also established. Taking into account the factors of aerodynamic and wheel connector effects, at last the design of segmented super high-speed grinding matrix was optimized with finite element method.

This paper reviews two cooling methods for surface grinding. These include i) replacing the toxic coolant by a mixture of cold air and vegetable oil mist, and ii) minimising the use of coolant using a segmented grinding wheel system. The discussion concludes that the cold air-oil mist provides an environmentally conscious mean for surface grinding. However, due to the limit of its cooling capacity, it is more applicable for fine grinding. Using the segmented wheel system can minimise coolant consumption and can improve grindability.

Cbn Grinding Wheel

In order to obtain the effects of abrasive configurations on the grinding force of superhard abrasive grinding wheel, an experiment was carried out, which grinds steel material by the use of electroplating CBN grinding wheel with different abrasive configurations, mainly including disordered, phyllotactic, matrix and dislocation configurations. The results show that under the experiment conditions, the grinding force of each grinding wheel will increase with the grinding parameters, the grinding force is smaller by the grinding wheel with orderly configurations than disordered configurations and under the same condition of experiment, the grinding force is smallest by the grinding wheel with abrasive phyllotactic configurations.
