The Effect of Double Edging Glass Machine Edging Process Factor

Mechanical grinding of glass is the application of abrasive in the wheels pressure and relative movement of the glass surface, which causes the glass to grind unevenly, resulting in a hairy surface. Coarse abrasives, high grinding speed, coarser wool surface, and numerous abrasives are usually employed. Typically, the glass surface has a sunken layer after the first rough grinding, followed by a micro-crack layer, so the glass surface is astigmatic and opaque; the sunken layer and the crack layer must be thrown away to obtain bright glass.

1. Abrasive properties of diamond wheels:

Abrasive characteristics and particle size of abrasive hardness, typically good grinding efficiency. Carborundum and carborundum outperform quartz sand in terms of abrasive efficiency. However, the abrasive's hardness causes the glass surface to have a concave depth. As a result, diamond wheels with larger abrasive particles have a higher efficiency but a lower quality. Multiple grinding, initially with large particle abrasives, is the ideal method for this, with the glass fast reaching the proper form and making the surface smooth. Finally, achieve the polishing criteria of the surface quality after grinding with fine abrasive diamond grinding wheels.

2.Nobler Glass reminder:

For suspending liquid made of water, the concentration of abrasive suspensions and the amount of abrasive material are utilized. The water not only spread the abrasive evenly throughout the working face but also removed the abrasive debris, reducing the heat produced by friction and aiding the hydrolysis of the glass surface, resulting in the formation of a silica gel coating. As a result, the amount of water added to the grinding efficiency has an impact. Typically, to calculate the liquid-solid ratio of the suspension liquid to demonstrate the concentration of the suspension, a variety of particle sizes of the abrasive has its most suited concentration, too large or too tiny, all affecting the grinding efficiency.

The abrasive concentration is insufficient, but it also causes a scar on the glass surface. Grinding efficiency increases with the amount of abrasive material used, but only to a point. As the amount of abrasive used increases, the rate of increase in efficiency slows or stops. As a result, each abrasive has a unique feeding quantity.

The grinding efficiency is proportional to the rotational speed and pressure of the grinding disc. However, the faster the rotary speed, the more abrasive is thrown out, the pressure rises, and abrasive wear rises dramatically. As a result, must be properly improved; otherwise, not only will efficiency not improve, but scars and other defects will appear.

The material hardness of grinding diamond wheels can improve abrasive efficiency. The grinding efficiency of cast iron is 0.6 for non-ferrous metals and only 0.2 for plastic. However, diamond grinding wheels with a high hardness increase the concave depth of the grinding surface. The lower hardness of the plastic plate can reduce the glass sag depth by 30% compared to cast iron.
