Aluminum alloy CNC machining has significant advantages compared to manual machining. For example, CNC machining produces aluminum alloy parts that are very precise and have precision. Aluminum alloy CNC machining can produce parts with complex appearance designs that cannot be processed manually. What are the standards and regulations for CNC machining process? Let's take a look:
1, Effectively use aluminum alloy CNC machining equipment.
Rough machining mainly involves cutting off the vast majority of processing capacity and does not require high machining precision. Therefore, rough machining should be carried out on equipment with high output power and low precision. The precision machining process requires the use of high-precision CNC lathes for machining. Rough and fine machining are processed on different equipment, which can not only leverage the working capabilities of the machine equipment, but also increase the service life of precision CNC lathes.
2, In order to ensure the precision of CNC machining of aluminum alloy, it is best to separate rough and fine machining.
Due to the large amount of drilling during rough machining, the product workpiece is subjected to high cutting speed, clamping force, and high calorific value, as well as the obvious processing hardening of the surface layer. The internal structure of the product workpiece has significant thermal stress. If rough and rough machining continue, the precision of the finished part will be rapidly lost due to the redistribution of internal stress. For some parts with high machining precision standards. After rough machining and before precision machining, ultra-low temperature quenching or tempering treatment steps should also be allocated to remove thermal stress.
3, In the CNC machining process of aluminum alloy, there is often a heat treatment process assigned.
The plan for the heat treatment process is as follows: to improve the drilling processing characteristics of metal materials, such as quenching, normalizing, aging treatment, etc., it is generally arranged before mechanical equipment processing. To remove thermal stress, such as quenching and tempering treatment, heat treatment, etc., are generally arranged after rough machining and before precision machining. In order to better improve the physical properties of parts, such as nitriding, heat treatment, quenching, etc., it is generally arranged after mechanical equipment processing.
If there is significant deformation after the heat treatment process, the final processing flow must also be assigned. Proper operating methods and maintenance are one of the main factors in the rational application of aluminum alloy CNC machining equipment. The application of reasonable operating methods can avoid abnormal damage to CNC lathes and prevent common faults from occurring; Daily maintenance and upkeep, maintain stable process conditions of machinery and equipment, slow down the deterioration process, promptly handle and solve common faults and safety hazards, and always ensure safe operation.
