introduction：one、Vibrating pairKOYOImported 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。]Influence of。 In the usual use，Vibration is quite sensitive to bearing damage，Peel off、impression、corrosion、crack、Wear and tear will be reflected in the bearing vibration measurement。therefore，By using a special bearing vibration gauge(Frequency analyzer)The magnitude of the vibration can be measured，The specific condition of the anomaly cannot be inferred from the frequency division。

introduction： 1.Use reasonable cooling methods： The influence of the cooling process on the deformation of metal after quenching is also a very important cause of deformation。Hot oil quenching has less deformation than cold oil quenching，Generally controlled in100±20℃。The cooling capacity of the oil is also critical to deformation。The mixing method and speed of quenching affect the deformation。The faster the metal heat treatment cooling speed，The more uneven the cooling，The greater the stress generated，Mold variable inlet 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

introduction：1、Annealing of steel The steel is heated to a certain temperature and kept warm for a period of time，Then let it cool slowly，Called annealing。Annealing of steel is the heating of steel to the temperature at which a phase transition or partial phase transition occurs，Heat treatment method of slow cooling after heat preservation。Purpose of annealing，To eliminate organizational defects，Improve the structure, homogenize the composition and refine the grain，Improve the mechanical properties of steel，Residual stress reduction；At the same time can reduce the hardness，Improve plasticity and toughness，Improve machining performance。Therefore, annealing is to eliminate and improve the organizational defects and internal stresses left over from the previous process，And prepare for the next step，Therefore, annealing is a semi-finished product
