The Principle of Precision Grinding of Aluminum Alloy

The principle of aluminum alloy cnc processing
1. In order to ensure the machining accuracy of aluminum alloy cnc, rough and fine machining should be carried out separately. Because of the large amount of cutting during rough machining, the workpiece is subjected to large cutting force, clamping force, heat generation, and the machined surface has a significant work hardening phenomenon, and there is a large internal stress inside the workpiece. If rough and rough machining Continuously, the precision of the parts after finishing will be quickly lost due to the redistribution of stress. For some parts that require high machining accuracy. After rough machining and before finishing, low temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.
2. Reasonably select aluminum alloy cnc processing equipment. Rough machining is mainly to cut off most of the machining allowance and does not require high machining accuracy. Therefore, rough machining should be carried out on a machine with greater power and less precision, and the finishing process requires higher precision. Machine tool processing. Rough and fine machining are processed on different machine tools, which can not only give full play to the equipment capabilities, but also extend the service life of precision machine tools.
3. In the aluminum alloy cnc processing route, there is often a heat treatment process. The location of the heat treatment process is arranged as follows: In order to improve the cutting performance of the metal, such as annealing, normalizing, quenching and tempering, etc., it is generally arranged before mechanical processing. In order to eliminate internal stress, such as aging treatment, quenching and tempering treatment, etc., it is generally arranged after rough machining and before finishing. In order to improve the mechanical properties of parts, such as carburizing, quenching, tempering, etc., it is generally arranged after machining. If there is a large deformation after heat treatment, the final processing procedure must be arranged.
Correct operation and maintenance is one of the key factors for the correct use of aluminum alloy CNC processing equipment. Correct operation and use can prevent abnormal wear of the machine tool and avoid sudden failures; daily maintenance, equipment maintains good technical status, and delays the deterioration process , Discover and eliminate hidden troubles in time, and ensure safe operation all the time.
