Mechanical cutting wheel features:
Including knife wheel cutting, grinding wheel cutting, etc. Knife wheel cutting has cost advantages, wide application, mature and stable technology, simple process and high efficiency. For example, in the cutting of TFT-LCD panels, knife wheel cutting is a common method. First, fix the empty liquid crystal box on the cutting machine workbench, and use the knife wheel to slide along the cutting mark on the glass under a certain pressure, and the glass is cut. The incision is formed and then split through a splitter. Grinding wheel cutting is widely used in machinery manufacturing, automobile manufacturing, steel structure processing and other fields, with high efficiency, high precision and easy operation. However, mechanical cutting has certain defects for ultra-thin base materials. For example, the cutter produces fine debris in the material, and the cutting surface is not necessarily perpendicular to the glass surface, leaving significant mechanical stress on the processed edge. , and it is very difficult to process base materials with a thickness less than 1mm, because glass of this thickness is very fragile, and may also need to be ground or polished on the cutting surface, and subsequent cleaning processes are also required.
Thermal cutting wheels (such as laser cutting wheels) features:
It has the advantages of high precision, high efficiency and high degree of automation. When cutting ultra-thin glass and other materials, it can avoid micro-cracks and residual problems caused by mechanical cutting, so that there is no residual stress in the glass, which brings higher edge strength and reduces process steps. No subsequent cleaning or grinding steps are required. However, the investment cost of laser cutting is higher than that of mechanical cutting systems, but the total investment cost of laser cutting will be lower than the cost of mechanical processing because grinding equipment is eliminated.
Water jet cutting wheel (function similar to cutting wheel) features:
Its non-heat source, high energy and cutting without transverse micro-cracks show its unparalleled advantages in composite multi-layer display materials, tempered glass, etc. It can cut materials with very narrow gaps and can perform all-round cutting, including various shapes, angles or slopes, without the need for secondary processing such as edge grinding. It can also reduce flying dust during the cutting process and improve the working environment. However, water jet cutting equipment is relatively complex and costly.
