introduction：one、Superheat phenomenon We know that in the heat treatment process, overheating is most likely to lead to the coarseness of austenite grains，The mechanical properties of the parts are reduced。 1.General superheat：The heating temperature is too high or the holding time under high temperature is too long，Causing austenite grain coarsening is called superheating。The coarse austenitic grain will lead to the decrease of the strength and toughness of the steel，The brittle transition temperature increases，Increase the tendency of deformation and cracking during quenching。The cause of overheating is that the furnace temperature meter is out of control or mixing（Often happens without understanding the process）。The superheated tissue can be annealed、After normalization or multiple high temperature tempering，Under normal conditions, the grains are refined by re-austenization。

introduction：1 Heating of heat treatment、The thermal insulation is based on the instrument temperature。Throughout the heat treatment process，It is necessary to check frequently that the temperature of the furnace and the workpiece is consistent with the temperature indicated by the instrument。If there is a problem，Notify the electrician to check and repair the instrument in time。 2 Heat treatment workers should do three times：Keep an eye on the furnace temperature、Keep an eye on the material temperature、Frequent regulation control，Ensure that the temperature in each part of the furnace is uniform，Maintain positive pressure in the furnace。 3 normalizing、quench、temper、The annealing temperature is selected comprehensively and controlled strictly according to the instructions in actual operation，Is to ensure the quality of heat treatment

introduction：1.Precision improvement method Imported bearing[Imported bearing:Simply put, the import bearing agent refers to the sale of an imported bearing brand。The main brands of imported bearings arenskbearing，ikobearing，fagbearing，Of good quality，Of course, the price is not cheap。]After the installation on the host is complete，Such as measuring the radial runout of the spindle，It can be found that the measured value of each turn has a certain change；When measuring continuously，It can be found that after a certain number of revolutions，This change is approximately repeated。The index to measure the degree of this change is the rotation accuracy of the cycle，The variation is approximately repeated by the number of revolutions required to represent the accuracy of the cycle rotation
