Analysis about Diamond Wheel for Glass Beveling Grinding

Straight-line beveling grinding of glass and mirrors is widely used in the architectural and glass furniture industries. The completion of the straight line bevel grinding production process for glass and mirrors is inseparable from the diamond grinding wheel. Studying and analyzing various elements of the diamond grinding wheel for beveling glass grinding the beveled glass are significant for saving energy and improving efficiency in deep processing of glass.

The process of beveling glass grinding with diamond wheels is very complicated. During the grinding of the glass by the diamond wheel, the diamond abrasive grains are irregularly distributed on the surface of the grinding wheel. The manufacturing precision of the diamond grinding wheel itself also affects the end face runout and radial runout during beveling glass grinding process, which will affect the surface roughness of the glass. High-strength diamonds are indeed effective in increasing the sharpness of diamond wheels. In terms of glass processing, the sharpness is reflected in the surface roughness achieved by the glass after grinding.

The effect of diamond particle size on the grinding of beveled glass is evident. The effective blade height of the coarse-grained diamond is larger than that of the fine-grained diamond. When the diamond grinding wheel has different particle sizes and concentrations, the average grinding thickness of each diamond abrasive grain has many variables.

It’s not good if the concentration of diamond is too low or too high. When the concentration is moderate, each diamond particle will fully exert the paint grinding performance. The choice of concentration is important. Typically, the concentration is from 100 to 150. Starting from the second diamond grinding wheel, the surface roughness value of the glass after grinding should be smaller and smaller, and the average grinding thickness of the diamond abrasive grains should be smaller and smaller. At the same time, the fine-grained diamond has more particles per carat than the coarse-grained diamond. Therefore, the average grinding thickness factor of a single diamond abrasive grain should be taken into account for choice of concentration.

When the diamond wheel is used to grind the straight beveled glass, the first diamond grinding wheel is used to grind the glass and deepen the base of the glass bevel. The second and subsequent diamond grinding wheels are used to grind the glass and make the glass better surface roughness. The difference in particle size of the first and second diamond wheels is greater than the difference in the size of the other diamond wheels. Under the same conditions, the average grinding thickness of each abrasive grain of diamond of different particle sizes is different, which will affect the surface roughness of the glass. Increasing the moving speed of the glass and increasing the feed amount of the grinding wheel can increase the average grinding thickness of each diamond abrasive grain.
