The Dongguan turning and milling composite processing process for a complex component involves mechanical processing, heat treatment, and auxiliary processes.
1. Mechanical processing process:
(1) First benchmark, then others. At the beginning of processing, always arrange the processing of the precision base surface first, and then use the precision base surface to process other surfaces
(2) Coarse before refined. First arrange rough machining, then arrange semi precision machining in the middle, and finally arrange precision machining and finishing machining.
(3) First the main, then the secondary. Arrange the processing of the main surface first, and then arrange the processing of the secondary surface.
2. Heat treatment process
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 material of the parts and the requirements for the purpose of heat treatment.
(1) Prepare for heat treatment. The main purpose of arranging before mechanical processing is to improve cutting performance and eliminate internal stress during blank manufacturing.
(2) Final heat treatment. Arranged after semi precision machining and before grinding, it is mainly used to improve the strength and hardness of the material.
(3) Remove stress treatment. It is best to arrange it after rough machining and before fine machining, such as artificial aging or annealing.
3. Auxiliary process
The auxiliary processes include inspection of the workpiece, deburring, demagnetization, cleaning, and oil coating for rust prevention. The inspection process is the main auxiliary process, which is the main measure to monitor the quality of Dongguan turning and milling composite processing products.
