Reasonable selection of CNC lathe processing: For high -efficiency metal cutting materials, cutting tools and cutting conditions are three main factors. These determine the processing time, the life of the knife and the quality of processing. An economically effective processing method must be a reasonable choice for cutting conditions. CNC processing manufacturer's three elements of processing and cutting conditions of CNC lathes: cutting speed, feed speed and cutting depth directly cause tool damage. As the cutting speed increases, the tip of the knife will increase, which will lead to mechanical, chemical and thermal wear. The cutting speed increased by 20%, and the life of the tool was reduced by 1/2.

And the processing process should take into account the reliability of parts during processing, accurate positioning accuracy, and clamping stability. Select the processing standards, the selection of thick standards adopts the surface layer with a smooth, tidy, flat, and relatively large area as much as possible. Some of the hair edges, wool edges, and remnants on the benchmark point should be removed to ensure accurate positioning and accurate positioning. Spectrum. The precision standards should be as consistent with the design scheme standards, installation standards, and accurate measurement standards.

During the entire process of workpiece, the surface of the workpiece has been continuously rubbed, which will make the surface crystal of the workpiece change and shift, resulting in hard bottoming conditions. At the same time, the cutting heat also causes the cutting shape. deformation. Rough machining, because the precision and appearance roughness of the processing specifications of aluminum alloy profiles are not easy to achieve high precision regulations. During the entire processing process, first of first, the processing capacity of each processing surface, especially the complicated thick wall parts, in the fineness, in the precision, in the fineness, in the fineness, in the precision, in the fineness, it is fine. Remove before processing.

In the process of installation of the workpiece, try to avoid the frequency of clamping, implement a precise positioning forming, and increase the smaller clamping force to reduce human factors. Formed precision processing, and use a higher precision facility for the refined processing process of parts. Generally, milling machines, digital explicit CNC lathes or processing management centers. During the entire process of fine processing, because the processing capacity is small, the high cutting rate and the amount of small knife are selected on the selection of the knife to ensure that the knife has sufficient strength stiffness, reducing the precision of processing precision caused by cutting vibration vibration vibration vibration. reduce.

Adjust the screw height, so that it can generate a certain support, thereby increasing the overall stiffness of the part. The reasonable choice of the clamping method, although the benchmark surface of the parts positioning has been milling, but the rigidity of the thin -walled parts of the aluminum alloy thin wall is relatively low, which is easy to produce clamp deformation. In order to enable the plane of the processing surface to meet the design requirements, the drum will not occur. The type or wave surface can be installed with a dedicated support in the middle of the plane before processing. The support consists of a chassis and adjusting screw.
