introduction：Machining on the lathe is mostly shaft parts and disc sleeve parts，Sometimes it is also possible to circle on irregular parts、Machining of inner hole or end face。Therefore, the parts have different clamping methods on the lathe。 1．Three jaw self-centering chuck clamping This is the most common clamping method on the lathe，This method can be applied to both disc and hexagon section workpieces，And it clips quickly，But the centering accuracy is not high，Generally speaking0.05~0.15mm。 2．Four jaw single action chuck and flower plate clamping The four claws on the four-jaw chuck achieve single action by rotating the screw。It can be used to clamp squares、Oval or irregular shape

introduction： Concentration is a special index of superhard abrasives，It refers to the quality of the superhard abrasive contained in each cubic centimeter volume of the working layer of the superhard abrasive。International requirements per unit volume0.88G Super hard abrasive，Its concentration is100%。Every increase or decrease in content0.22G ，Its concentration increases or decreases accordingly25%。Concentration is one of the important characteristics of superhard abrasives，It has a significant impact on the grinding efficiency of the grinding tool and the processing cost of the process。overconcentration，Many abrasives fall off prematurely，Lead to waste of abrasive；hypoconcentration，Grinding efficiency decline，Can not meet the processing requirements。
