Three working procedures in turning milling compound processing
Dongguan turning milling compound processing process of a complex part consists of machining process, heat treatment process and auxiliary process.
1. Machining process:
(1) Benchmark before others. At the beginning of processing, always arrange the processing of the fine base plane first and then use the fine base plane to process other surfaces
(2) Coarse before refined. Rough machining is arranged first, semi finishing is arranged in the middle, and finishing and finishing are arranged finally.
(3) First primary, then secondary. First arrange the processing of the main surface, and then arrange the processing of the secondary surface.
2. Heat treatment procedure
Heat treatment is used to improve the properties of materials and eliminate internal stress. The arrangement of heat treatment in the process route mainly depends on the materials of parts and the purpose requirements of heat treatment.
(1) Prepare for heat treatment. Before machining, the main purpose is to improve the cutting performance and eliminate the internal stress during blank manufacturing.
(2) Final heat treatment. It is mainly used to improve the strength and hardness of materials after semi finishing and before grinding.
(3) Stress relief treatment. It is better to arrange after rough machining and before finish machining, such as artificial aging and annealing.
3. Auxiliary process
The auxiliary processes include inspection, deburring, demagnetization, cleaning and oiling of workpieces. The inspection process is the main auxiliary process, which is the main measure to monitor the quality of Dongguan turning milling compound processing products.
