Mechanical properties inspection

According to the characteristics of mechanical maintenance,precision metal parts processing plants,in addition to the hardness of the mechanical properties of the parts of the material,other indicators are generally not checked,but some of the performance encountered in the manufacturing and maintenance of parts,Such as balance conditions,spring stiffness,etc.,precision metal parts processing companies,can not be ignored.

Covert defect inspection

During the manufacturing process,the original defects such as slag inclusions and voids may exist inside,and micro cracks may occur during use.These defects cannot be found directly from general observations and measurements,but they can have serious consequences for machinery.Therefore,in mechanical overhaul,it is necessary to conduct a comprehensive inspection of certain parts with purpose.

Heat treatment in the machining process of parts:

The heat treatment in the machining process of parts can generally be divided into two types:preparation heat treatment and final heat treatment:

1.Preparation for heat treatment:The intention is to improve the mechanical properties and eliminate the internal stress,so as to prepare for the final heat treatment.The processing price of precision metal parts generally includes annealing,normalizing,quenching and tempering and aging treatment.The preparation heat treatment is carried out,usually after roughing.

2.after all heat treatment:its intention is to improve the hardness and wear resistance of the parts,including quenching,carburizing,nitriding and other processes,generally after semi-finishing,before finishing.
