wholesale High Precision Machining Parts In recent years, during the machining process of the machine plant, the processing quantity of aluminum alloy parts is gradually increasing, and the shape is becoming more and more complex, and the requirement of dimension accuracy and roughness is getting higher and higher. Especially for cast aluminum alloy shell parts, the structure is complicated, the casting wall is thin and the volume is getting larger and larger. As the requirement of dimension accuracy and roughness becomes higher and higher, the problem for part deformation exists in the process of machining. Below share the characteristics of aluminum alloy in the process of aluminum alloy machining and the existing problems and measures in the process of processing, for the reference of technicians for related fields. The strength for aluminum alloy is generally 96~294 MPa, high only 588~687 MPa, and hardness is only 110~120HB. The material has poor ability for resist plastic deformation and scratches. The workpiece is easy to be brushed and clamped. Therefore, it is necessary to remove chips smoothly and the chips will not adhere to the machined surface. Aluminum alloy has high heat conductivity. Chips will take away a lot of heat during cutting, but its modulus with elasticity is small and it is easy to produce large elastic deformation. It is hard to obtain high machining accuracy, and it will be also caused severe friction between the flank and the machined surface, and accelerating tool wear and causing vibration. This is more obvious on thin-walled parts machining, so it is necessary to obtain high machining accuracy as possible. Only in this way is it advantageous to the machining of aluminum alloy. In small allowance finishing aluminum alloy, the index-able blade edge is usually blunt, which often results in the "plowing" effect, resulting in a sudden increase in cutting force, excessive tool size and excessive power demand. Therefore, so it is needed to improve the sensitivity for the cutting edge and increase its power to avoid this defect as much as possible. In summary, in the process of aluminum alloy manufacturing and processing, it is necessary to confirm the quality of products and meet the surface roughness requirements for products. In the cutting process of aluminum alloy, in addition to factors such as tool material, geometric parameters for tools, cutting fluid and elimination for machining stress, the performance characteristics for aluminum alloy should also be considered. Finally, the difficulties and problems in production should be effectively solved. Only when these factors are considered comprehensively can qualified products be produced more efficiently.wholesale High Precision Machining Parts website:http://www.licometal.com/precision-hardware-parts-processing/high-precision-machining-parts/
