organic abrasive applications


Hand grinding is divided into fixed and mobile handheld handheld grinding grinding. The grinding machine fixed, handheld grinding workpiece way, called a fixed-held grinding. Processing using a hand-held grinding machine for grinding a movable manner, referred to as mobile handheld grinding.
Hand Grinding main application areas:
(1) with a shortage of  grinding wheel china portable resin grinding wheel, processing large and bulky hard parts installed on the grinder. Such as: large castings kibble.
(2) high-speed cymbals shape grinding wheel or steel, paper, processing has been assembled with other 'parts of the workpiece. Such as: heavy construction components and ship components.
(3) for small adjustments required for grinding. Such as: In large parts of the limited common position on calibration assembly.
(4) a high speed grinding wheel cymbals, final shaping of the workpiece or the workpiece with the adjacent rounded junction portion, which has been already welded assembly or grinding the workpiece. Such as: the processing of the car body.
(5) for the irregular shape of the sculpture on the surface machining. Such as: mold processing.
(6) workpiece finishing. Which requires rounding of the workpiece or finishing grinding to the surface appearance, performance, satisfaction, while the shape and size without strict requirements. Example: cymbals grinding wheel with bendable stainless steel products processing, PVA grinding wheel with a stone and so on.
(7) in a limited area of ​​the surface to nonwoven belt  make a small grinding to form a special shape, such as: a variety of tools such as grinding sharp.
3, cutting machining applications
Resin sheet wheel mainly used in metallurgical industry, steel bars, steel, flat steel, angle iron, channel, rail, steel and other metal materials cutting; semiconductor industry, silicon, germanium, sapphire, ferrite, graphite, ceramics, quartz and other metal and non-metallic materials, precision thin slice processing; like and building materials industry, chemical industry, aerospace industry, mechanical industry, automobile industry, shipbuilding industry, metal and nonmetal materials cutting.
Cutting of the metal material, the Bonded abrasives  use of the resin sheet wheel cutting, has the following advantages:
(A) cutting speed. Metal cutting, the cutting wheel cutting speed is other cutting methods (such as saws, car cut) of 10 times.
(2) cutting high dimensional accuracy. Grinding wheel cutting, the cut width and the smoothness of the cut surface, in general, better than cutting metalworking.
(3) a smooth cutting surface. After cutting wheel are often not subject to its surface finish, and after sawing the cut surface is obvious.
(4) for cutting hard materials. Such as hardened steel and metal carbides and brittle non-metallic materials cutting.
(5) abrasive use, good self-sharpening, no trimming.
(6) low cost. Use abrasive cut the cost significantly lower than other cutting methods.
