The grinding wheel consists of three parts: abrasive, binder and air hole. The seven factors that determine the quality of the grinding wheel are measured by abrasive, particle size, binder, hardness, structure, shape and size, and strength (highest working speed). 1) Abrasives. Abrasive refers to the material of the sand in the grinding wheel. It is the main component of the grinding wheel and is the essential element for the 125*1*22 EN12413 cutting disc of the grinding wheel. 2) Particle size. Particle size is a parameter used to indicate the size of the abrasive particles. According to the basic particle size of the abrasive, a total of 41 particle size numbers are specified. Particle size directly affects the quality and productivity of grinding. 3) Binding agent. The binder is a material used to bond the dispersed abrasive particles into a aluminum flat cutting disc having a shape and sufficient strength. The type and nature of the bonding agent will affect the hardness, strength, corrosion resistance, heat resistance and impact resistance of the grinding wheel. 4) Process control is heavier, Jinlida Grinding Wheel Factory pays attention to details, quality constantly improves quality, produces grinding wheel every day, and makes film inspection. Under the leadership of Jin Zong, the quality doubles and the output doubles every year. Jinli Daren will continue to work hard and cooperate with everyone to make the quality of the grinding wheel more perfect.
