Precautions for machining aluminum parts on CNC lathes

u200bCNC lathe parts are processed with a variety of raw materials. Among them, aluminum parts are one of the most processed parts. When using CNC machine tools to process aluminum parts, you want to make the processing models and specifications more stable. Such areas must It is necessary to pay attention to the refrigeration problems of raw materials, and the deformation of aluminum die castings after refrigeration is generally unavoidable. At this time, it is necessary to pay attention to the application of diesel engine refrigerant as much as possible. Consider the deformation of raw materials. u200bThe unscientific processing technology can easily lead to deviations in the model specifications of aluminum die castings. To ensure the basic processing technology (such as 'rough first and then finish, face first and then hole, first many and then spicy small noodles' in the machining of CNC machine tools, or 'reduce the frequency of clamping and install as much as possible' It is necessary to avoid the machining deviation caused by iron pins on aluminum parts as much as possible for most of the important links of basic processing technology. Cutting factors such as basic parameters cutting rate, cutting speed, cutting multiple aspects and tool compensation all impair the efficiency of processing, so special attention should be paid. When selecting and processing aluminum parts, special tools should be used as much as possible. Such tools are generally more purposeful. For example, turning tools special for aluminum milling generally have larger rake angles and helix angles, sharper cutting edges, which are more conducive to the processing of aluminum parts (such as anti-chip buildup), and the processed performance indicators will be stronger. The aluminum material at the stress field level is too soft, so pay attention to the clamping range as much as possible. In addition, during processing, the aluminum parts are roughed intact and left for a period of time before the next production process is carried out to remove the stress field. In addition, it is necessary to pay attention to the milling surface and the demand of cutting fluid during the processing of aluminum parts. There are many factors that damage the efficiency of aluminum processing, so it must be handled flexibly during processing, and the actual problems must be analyzed in depth. Stable machine tools, effective processing techniques and tools, and the technical strength of their operators are all factors that impair product quality. When choosing tools to process aluminum parts, use special tools as much as possible. Such tools are generally more targeted. For example, lathe tools for aluminum milling generally have larger rake angles and helix angles, and the cutting edges are sharper, which is more conducive to the processing of aluminum parts (such as anti-chip buildup), and the processing performance will be stronger. In addition, special attention should be paid to the difficulty of milling and the amount of cutting fluid required in the processing of aluminum parts. There are many factors that damage the credibility of aluminum processing, so it should be handled flexibly during processing, and specific difficulties should be analyzed in detail. Stable machine tools, reasonable processing techniques and tools, and the technical level of operators are all factors that harm product quality. Unreasonable processing technology can easily cause errors in specifications and models of iron castings. In ensuring the basic processing technology (such as 'rough first and then fine, first face and then hole, first many and then spicy small noodles' in cutting CNC machine tools, or 'reduce the number of clamping and installation, try to use the composition of fixtures' and other basic processing For most of the key links of the process, it is necessary to minimize the machining errors caused by iron pins on aluminum parts. There are many reasons for the deformation of aluminum parts, which are often related to raw materials, parts appearance, production and processing specifications, etc. There are several important aspects: the deformation caused by the welding stress of the blank, the deformation caused by the cutting force and the cutting heat, and the deformation caused by the clamping force.u200b
