The Plane Wafer Grinder Is A Precision Polishing Equipment

Feb 15, 2021

The plane grinding machine is widely used for single-sided grinding and polishing of LED sapphire substrate, optical glass wafer, quartz wafer, silicon wafer, various pieces, mold, light guide plate, light cutting joint and other materials.

The plane grinder is a precision grinding and polishing equipment. The material to be ground and polished is placed on a flat grinding plate. The grinding plate rotates against the clock, the correction wheel drives the workpiece to rotate, the gravity pressure or other ways to put pressure on the workpiece, and the workpiece and the grinding plate make relative running friction, so as to achieve the purpose of grinding and polishing. There are two sources of abrasive particles, one is from the continuous addition (often called free abrasive), the other is to fix the abrasive particles in the grinding disc (often called fixed abrasive).

Grinding machine is a kind of grinding machine which grinds the surface of workpiece with abrasive tools. It is mainly used for grinding high-precision plane, inner and outer cylindrical surface, conical surface, spherical surface, threaded surface and other surfaces in workpiece.

The plane grinding machine is widely used for single-sided grinding and polishing of LED sapphire substrate, optical glass wafer, quartz wafer, silicon wafer, various pieces, mold, light guide plate, light cutting joint and other materials.

The main types of grinder are disc grinder, spindle grinder and various special grinders. The grinding machine control system takes PLC as the control core and text display as the man-machine dialogue interface. The man-machine dialogue interface can communicate with people on equipment maintenance, operation, fault and other information; the operation interface is intuitive and convenient, and the program control and operation are simple. Considering all aspects of safety, the abnormal state of misoperation is invalid. Real time monitoring, fault and error alarm, convenient maintenance and grinding. It is the finishing of machined surface (such as cutting) by using the abrasive particles coated or embedded in the lapping tool and the relative movement of the lapping tool and the workpiece under a certain pressure. Grinding can be used to process all kinds of metal and non-metal materials. The surface shape of grinding includes plane, inner and outer cylindrical surface, conical surface, convex and concave spherical surface, thread, tooth surface and other surface.

According to the number of grinding discs, it can be divided into single-sided grinder and double-sided grinder. According to the size of grinding disc, it can be divided into 380 grinder, 460 grinder, 610 grinder, 910 grinder, etc
