How to increase the processing power during the processing of large mechanical parts? With the continuous development of the machining fine machining industry, the precision requirements of machining are also constantly advancing. Fine machining technology is a manufacturing technology that has been used in recent years, so it is more suitable for Thin-walled parts. In addition, how to improve the processing efficiency and provide better service during the processing of large mechanical parts has also become a big problem at that time. The editor consulted relevant materials and summarized them as follows: Improve the processing power of fine parts: During the processing of fine parts, there will be common problems such as accelerated tool wear, poor processing surface integrity, and difficulty in chip removal, which seriously affect the precision of such materials. The quality of parts processing, production cycle and processing cost.

Based on the theories of metal technology, metal cutting, and fine parts processing principles, the above-mentioned material processing difficulties are analyzed, and a set of effective drilling, reaming, and boring processing technologies for stainless steel materials are explored. The machining of fine parts requires a super-lubricated machined surface and high machining accuracy, which requires the tool to have a high standard life. Whether the tool is worn or not will be based on whether the quality of the machined surface has declined out of tolerance. The standard life of diamond tools is very high, and the tool wears very slowly during high-speed cutting.

Therefore, during ultra-fine cutting, the cutting speed is not restricted by the tool life, which is different from the general cutting rules. The selection of precision parts processing parameters mainly includes the selection of the cutting tool viewpoint, the selection of cutting speed, the selection of cutting depth and feed speed, etc. From previous experience, we know that if you choose a tool with a larger rake angle when processing plastic materials, the formation of built-up edge can be effectively suppressed. This means that when the tool rake angle increases, the cutting force decreases, the cutting deformation is small, and the tool and chips The length of the touch becomes shorter, reducing the basis of the built-up edge.

Inspection requirements and inspection procedures introduce inspection requirements; quantity inspection; based on the supply contract and processing voucher, strictly check the raw materials, standards, and quantity of the processed parts according to the drawings, and check and check each piece, make a record of the quantity inspection, and specify Inspection location, time, participants, type, product name, expected and actual quantity. Appearance inspection: Check whether the finish of the machined parts meets the requirements of the drawings, check whether the surface of the machined parts is damaged, rusted, bruised, and whether the thread shape and angle are correct. If the above-mentioned problems are found, specific records should be made for future reference.

Quality inspection: assembly must be strictly in accordance with the rules and procedures required by the assembly drawings, and records must be carefully made during quality inspection. If there is a quality problem in the processed parts, the external processing unit should be notified in writing of the specific situation. Depending on the situation, decide whether to return or replace the product. If there are special requirements, you can find the processing unit to inspect and assemble together. The inspection document can only be signed after the installation is qualified.

Inspection procedures; if there is a quality problem, you can return the goods to the processing unit, claim for compensation, and the processing unit will bear the economic loss. Generally, the processing contract signed by the non-production department will be directly inspected by the operating department, and the inspection report will be filled out. Parts that fail the inspection will be inspected. Personnel must handle maintenance and return procedures within the specified inspection period. For the inspection of special and finely processed parts, the full-time inspectors will arrange relevant personnel to jointly inspect and fill in the inspection report. For parts that fail to pass the inspection, it is necessary to fill in the inspection form in detail, as a condition for improving processing accuracy and to determine the selection direction of future parts outsourcing manufacturers.

Yes, besides these, there is a particularly important problem for the processing of large mechanical parts. Here I will also tell you about it. This is the most commonly used one. The personnel inspect the raw materials, standard models, and quantities of the processed parts according to the requirements of the contract against the drawings. The inspection period is generally 1-2 days. In special circumstances, it depends on the application effect.
