Quality requirements and cost performance of large-scale machining

Large-scale machining needs to control the quality of raw materials during the processing. The high-quality raw materials are the prerequisite for the production of high-quality products. The materials used by our company are 40Cr and 45 steel to make gears. Regardless of the way, the raw materials must undergo strict chemical composition inspection, grain size determination, and purity evaluation after they arrive at the factory. The purpose is to adjust the heat treatment deformation in time to improve the quality of the tooth profile processing.
In order to be able to prepare for the organization of large-scale machining, it is necessary to keep the temperature of the furnace even during the normalizing or quenching and tempering process, and to use station equipment to a certain extent. The workpieces are evenly heated and cooled, and it is strictly forbidden to stack them together. Control gear accuracy: basic requirements for gear accuracy: verified by practice, gear accuracy must be controlled at GB10995-887~8, linear speed higher than 20m/s gear, pitch limit deviation, ring gear radial runout tolerance, tooth direction Tolerance should be stable and reach level 7 accuracy.
Large-scale mechanical processing is very important for the construction of this city, so its workload is very large, and the quantity that needs to be processed is very large. If you try to choose raw materials that can be recycled during processing , In this way, energy-saving, environmentally friendly and low-consumption processing machines can be used, which will produce less pollution. When the machine needs to be updated, it can also be recycled to the relevant department for processing and re-production. This production concept is mechanical processing What you need to have, many companies now need to buy a lot of machinery for their own business. They will also consider energy-saving and environmentally friendly machinery. Of course, they also value the cost-effectiveness of the product. The quality is required. The price is more favorable than other products. They have no resistance to such products.
Generally, large-scale mechanical processing has strict requirements for its employees. Under normal circumstances, tasks need to be completed within a specified time. In the production process, the process of tilting and the transformation of raw materials into products is directly related to crafting process. It includes blank manufacturing, parts processing, heat treatment, quality inspection and machine assembly. The manufacturing of tools, fixtures, and machine tool adjustment and maintenance required for the normal process of the process are auxiliary processes. In the process, the processing method of large-scale mechanical parts in Dalian gradually changes the shape, size, relative position and performance of the blanks in a certain order, until the part of the process that becomes a qualified part is called the mechanical processing process.
