Aluminum parts processing

タイトルまたは説明

Aluminum parts processing aluminum alloy parts machining process can be rough, finishing separately, after the completion of roughing, the parts heat treatment, cutting stress and residual stress in parts of the full release, and then finishing, machining quality will get greatly improved, the implementation of roughing and finishing apart are the following advantages:
(1) To reduce the influence of residual stress on Machining Distortion. After the completion of roughing, roughing thermal treatment will produce stress parts removed, so you can reduce the stress on the quality of finishing.
(2)Improve the machining accuracy and surface quality. Rough, separated after finishing, finishing and processing only a small margin, the processing of stress and deformation of small, can greatly improve the quality level of parts.
(3) Improve production efficiency. Since roughing only remove excess material, leaving sufficient margin for the finishing, but more so to consider dimensions and tolerances, to effectively play different types of machine performance, improve cutting efficiency.
(4) Aluminum alloy parts after machining, sheet metal processing within the organizational structure will change significantly, coupled with the impact of the cut motion, resulting in a large residual stress, in order to reduce the deformation of parts, material needs to be the full release of residual stress.
(5) Aluminum alloy parts commonly used low-temperature annealing heat treatment. Low temperature annealing temperature is generally between **0 to **0 degrees Celsius, lower than the recrystallization temperature will not affect the strength and hardness of parts; low-temperature annealing stress relief can be achieved through appropriate performance requirements of holding time, but returned after the heat treatment of low temperature Chi can remove the stress most part, can not hundred percent removal of residual stress on the parts processing deformation impact is relatively small.
