The China cutting disc for metal is a very common grinding tool in the grinding process. It is usually made by adding a binder to the abrasive, and is made by compacting, drying and roasting. The characteristic parameters are mainly abrasive, viscosity, shape, hardness and combination. Agent, size, etc.
Because of the difference in abrasives, binders, and manufacturing processes, the resulting cuts are also quite different, so abrasives, binders, and manufacturing processes have an important impact on the quality and productivity of the grinding process.
According to the abrasive, the resin EN12413 cutting discs can be divided into ordinary abrasive (corundum and silicon carbide) grinding wheel, natural abrasive super-hard abrasive and (diamond and cubic wheel boron nitride, etc.) grinding wheel;
According to the shape, the cutting piece can be divided into a flat grinding wheel, a cup-shaped grinding wheel, a cylindrical grinding wheel, a beveled grinding wheel, a dish-shaped grinding wheel, and the like;
According to the bonding agent, the cutting piece can be divided into a metal grinding wheel, a rubber grinding wheel, a resin grinding wheel, a ceramic grinding wheel and the like.
The dicing sheet is a sheet made of abrasive and binder resin for cutting ordinary steel, stainless steel metal and non-metal materials. It is mainly made of glass fiber and resin as a reinforcing bonding material, and has high tensile strength, impact resistance and resistance. The characteristics of bending strength are therefore widely used in the production of ordinary steel, stainless steel and non-metal.
According to the material, the cutting piece is mainly divided into a fiber resin cutting piece and a diamond cutting piece.
The former is made of resin as a bonding agent, and the glass fiber mesh and various materials are combined to realize the cutting of hard materials such as alloy steel and stainless steel. The performance is very remarkable, and the cutting precision is ensured, and the cutting efficiency can be greatly improved. Save production costs. The cutting method is dry and wet.
Diamond cutting discs are mainly used for the cutting of hard and brittle materials such as stone, new and old roads, prefabricated panels, concrete, ceramics. It mainly consists of two parts: the base and the cutter head. The base is the main supporting part of the bonding head, and the cutting action is mainly the cutting head. Since the cutting head contains diamond, as the hardest material at present, the diamond can effectively cut the object to be processed. The cutter head will wear out during use, but the base will not.
The grinding disc is made by implanting fine abrasive grains (alumina or silicon carbide) on the high-strength polyester film by means of high-voltage electrostatic field force, so that all the sharp knives face outward, and the cutting sharpness can provide higher grinding efficiency and Bright and detailed polishing effect, then processed through the back pile and cut.
Abrasive particles of the abrasive sheet are oriented, the surface of the product is sharp, ensuring the best grinding performance of the belt; the surface of the product is evenly distributed, combined with a special binder to prevent deep lines and irregular lines, and good chip removal capacity. It is not easy to block.
The granularity numbers are 240#, 320#, 360#, 500#, 800#, 1200#, 1500# and so on.
Disc sand is a kind of polishing disc. Disc sand is a round grinding piece processed from sandpaper, which can be divided into two types: velvet and double-sided tape. It is used to polish hardware parts, plastics and auto parts. It is faster than general sandpaper. The grain number is divided into 60# 80# 100# 120# 150# 180# 220# 240# 320# 400#. Grinding sheets are used faster than general sandpaper.
