Chamfer grinding wheel grooves on the quality of life as well as the impact has to be formed on the wafer edge profile requirements

Grinding wheel is a major material wafer processing, is currently in the purchase of grinding wheel, grinding wheel manufacturers generally require customers to provide their own wheel design drawings, and wheel design and wafer chamfer outline the pros and cons of great  cubic boron nitride . A better design not only improves the grinding wheel of life, but also to ensure the stability of product quality.  grinding wheel  wheel grooves on the impact of the general quality of life of our customers have been placing orders for wafer edge profile provides a good requirements, such as SEMI standard or profile half-width of the chamfer 11 °, or require a  abrasive wheels  profile widths, etc. . Therefore, the shape of the grinding wheel groove designed according to customer requirements, so that the chamfered wafer after processing to meet customer requirements. According to the author of these years of work experience, first in customer satisfaction guaranteed under the premise of the specific parameters for the design of the grinding wheel groove following three ideas: coarse grinding down groove bottom radius than the fine groove bottom circle down large number of specific arc radius, according to the amount of sperm removal down to develop.
