Glass Grinding Mechanism

The first step in the glass grinding process is the relative movement of the disc and glass, followed by free abrasive under load on the surface of the glass scratches and stripping mechanical action.

Micro-cracks appear on the glass at the same time. The water used in abrasives not only cools but also causes hydrolysis with the new surface of the glass, resulting in silica gel, which is beneficial for peeling and has certain chemical effects. As this process was repeated, the glass surface formed a layer of hollow surface with a certain depth of the crack layer.

The primary process variables influencing the glass grinding process

The amounts of grinding (the amount of glass in the unit time) and the depth of the concave layer of the grinding glass determine the grinding speed and quality of the glass during the glass grinding process. Grinding efficiency is great, concave layer depth is shallow, and grinding quality is good. Some process factors impact only one of them, while others affect both, but they frequently have a positive effect on one while hurting the other. The depth of the grinding glass sag increases as grain size grows, implying that grinding quality degrades as grain size increases. To that purpose, a bigger grain size at the start of the grinding improves grinding efficiency, allowing glass products to be made in a relatively short time while achieving the desired shape or surface creation. After grinding with fine abrasive till the grinding quality steadily increased, the surface quality of polishing criteria was eventually met.

Abrasive suspension concentration and feed quantity

Abrasive suspensions are typically composed of abrasive water and a suspended liquid. The water not only disperses the abrasive, but also distributes it evenly throughout the working face, removes ground glass debris, cools the friction to produce heat, and causes the glass surface to hydrolyze into the silica gel film. As a result, the amount of water added to the grinding efficiency has an impact. A variety of particle sizes of the abrasive has its most suited concentration, too large or too small, all affecting the grinding efficiency.

The speed and pressure of the diamond grinding wheel

The grinding efficiency is proportional to the speed and pressure of the diamond wheels. The speed of the grinding diamond wheel is quick, and the abrasive will be more and more, and the abrasive's abrasion degree is raised. Therefore, increasing the amount of abrasive material is necessary to avoid scarring and other defects as well as decreased grinding efficiency.

Glass's chemical composition

The chemical makeup of glass has an impact on how well it grinds and how deep the depression goes, with soft glass being easier to grind but leaving a deeper depression behind.

Material machining and polishing

Since the mechanical action is what makes glass polishing wheels work, the abrasive's hardness must be higher than the glass's hardness. The daily processing budget for glass and grinding is substantial, so corundum or natural emery are typically used because of their high degree of efficiency. Flat glass has a small grinding allowance, but the area is large, the dosage is numerous, and quartz sand is typically used, which is not expensive. Commonly used polishing materials include iron oxide, cerium oxide, chromium oxide, zirconia, and oxidized thorium. Daily glass processing also uses a long stone powder, but the materials mentioned above were the first and most widely used for glass polishing. Zirconia and cerium oxide are more polished than pink because of their expensive prices and limited scope of use. requirements for materials polishing.
