The deformation of precision machining of orthopedic parts is one of the frequent problems during processing, including changes in the nature, size, and position of the mechanical product.
At present, the deformation of mechanical products mainly occurs under three conditions:
- 1. Mechanical products have elasticity problems during initial cutting, cutting, and cutting, causing deformation of precision mechanical parts. Although deformation problems are inevitable in design and production, the degree of deformation of precision parts can be controlled by scientific and reasonable methods, such as using high-tech machinery and equipment for processing to reduce the deformation of precision parts.
- 2. After heat treatment, precision parts are prone to be high in the middle and low on both sides, and the precision parts are bent.
- 3. When the precision parts are processed, strong internal force will be generated to firmly fix them, forming an inner radial force to ensure the normal cutting of precision mechanical parts processing parts, so as to successfully complete the machining process, but when the processing is completed, the jaws are lowered The precision parts of the company have changed their original shape, and may become polygonal or elliptical.
Precision machining classification
Precision machining is a process of changing the workpiece, which can be classified into cold working and hot working.
Precision machining is a process in which machining machinery is used to change the shape or performance of a workpiece. According to the temperature state of the workpiece to be processed, it is divided into cold processing and hot processing.
Generally processing at room temperature, and does not cause chemical or phase changes of the workpiece, called cold processing.
Generally, processing at higher or lower than normal temperature will cause the chemical or phase change of the workpiece, which is called thermal processing.
Cold processing can be divided into cutting processing and pressure processing according to the difference in processing methods.
Thermal processing commonly includes heat treatment, forging, casting and welding.
