Selection principle of parts surface machining method

The surface Machining of parts, shall be based on the machining requirements of these surfaces, the structural features of the parts and the material properties and other factors to choose the appropriate machining methods. In choosing the machining method of a surface, it is usually first choose its final machining method, and then select the machining methods of the relevant leading process one by one.

Principles of choice of machining methods:

1., the selected machining method should consider the machining economic accuracy range of each machining method, which should be adapted to the requirements of the machined surface accuracy and surface roughness.

2. the selected machining methods can ensure the geometry accuracy of the machined surface and the requirements of the accuracy of the surface location.

3. The selected machining methods should be compatible with the machinability of the parts material. For example, hardened steel, heat-resistant steel and other high hardness materials should be machined by grinding methods.

4.The selected machining methods and production types to adapt, high-volume production, should use efficient machine equipment and advanced machining methods. In single piece and small batch production, general machine tools and conventional machining methods are used in.

5.The selected machining methods should be adapted to the existing equipment conditions and workers' technical level.
