1 abrasive type
The degree of clogging of different cutting sheets varies greatly. From the perspective of reducing the degree of clogging and improving the cutting effect, different workpiece materials should be selected for different workpiece materials. If the selected abrasive cannot adapt to the cutting performance of the workpiece material, it is prone to sharp blockage and the processing cannot be performed normally. If the iron-carbon alloy is cut with corundum abrasive, carbon forms a thin oxide film in the air and oxygen, which can effectively prevent the chemical affinity between the workpiece and the abrasive. However, if the titanium alloy is cut, the blockage is serious. many. Some 5 inch resin cutting disc for metal on factory grinding machines have not been replaced for a long time, and they can grind everything, which seems to be economical and convenient, and actually loses efficiency and precision.
2 abrasive grain size
The abrasive grain size has a certain influence on the clogging of the cutting piece. Generally, the fine particle size is more likely to cause clogging than the coarse particle size. Because the pore volume and the cross-sectional area of the fine-grained cutting piece are small, the number of cutting edges of the fine-grained cutting piece is increased, the number of cutting chips is also increased, and the cutting temperature is increased, etc., in the range where the number of cutting times is small, the fine-grained cutting is performed. The piece is easy to block. As the number of pruning increases, the coarse-grained cutting piece has a larger depth of cut than the fine-grained cutting piece, the wear amount of the abrasive cutting edge is large, and the cutting temperature rises, and the chip fusion in the pore increases. . After a certain number of times, the clogging amount of the coarse-grained cutting piece is more than the clogging amount of the fine-grained cutting piece. When semi-finishing and fine grinding, the cutting amount is small, the temperature is low, the clogging is light, and the fine cutting piece is selected; the coarse grinding and cutting amount is large, the temperature is high, the grinding debris and the sintered material which are clogged in the gap are many, and the coarse cutting piece is selected.
3.3 hardness of the cutting piece
The hardness of the dicing sheet refers to the ease with which the abrasive particles fall off, and is ensured by the strength of the binder. The higher the strength of the binder, the greater the hardness of the cutting piece, the more the granules are blunt, the more severe the sliding and the squeezing of the workpiece before the abrasive particles fall off, and the grinding debris is more easily mechanically filled into the gap of the fiber cutting disc Chinese supplier. Going, along with the generation of more frictional heat, provides friction for the cohesive plugging. Therefore, the hardness of the cutting piece has a great influence on the amount of clogging, and the harder the cutting piece, the larger the clogging amount.
