Precision Of Mold Processing

The larger the error, the lower the machining accuracy, and the smaller the error, the higher the machining accuracy; the main aspect that affects the machining accuracy is the dimensional accuracy, the degree of conformity between the actual size of the part after machining and the center of the tolerance zone of the part size. Compared with the method of producing parts with die-casting molds, it avoids the inconvenience of opening molds when manufacturing small batches of parts, and the production cycle is greatly shortened. At the same time, the correct clamping positioning and reasonable processing technology make the processed parts have higher precision and surface finish, which cannot be achieved by the die casting process. Moreover, the density of extruded aluminum profiles is relatively high, and the strength of the processed parts is higher than that of die castings.

      There is no sheet metal processing cabinet that we usually see that is not painted, so what is the role of painting? Many people just think that the perception of being beautiful is abnormal. Generally, when we go to buy a cabinet to see the cabinet, the cabinet manufacturer will introduce it. Painting and surface treatment sheet metal processing technology is also a standard to measure the quality of the cabinet. In addition to painting cabinets What are the other sheet metal processing procedures for surface treatment? Painting and surface process cabinet degreasing is degreasing - water washing - rust removal pickling or polishing - water washing - phosphating - water washing - dry hot air drying or drying can be - spray painting and electrostatic powder spray - drying. The appearance of the cabinet looks like a cabinet for holding things, but in fact, the processing process of the cabinet is very complicated, so we must be optimistic about the sheet metal processing technology when buying a cabinet.

      B. The thread rolling is carried out on a special rolling thread machine. The precision of the rolled thread can reach grade 3, and the surface roughness is Ra0.8~0.2. The advantage is that the tensile strength and shear resistance of the thread are greatly improved. Strength and fatigue strength, and high productivity, the disadvantage is that expensive special equipment is required, the precision of the blank is high, and only external threads can be rolled.

     The technical barriers to CNC machining of precision mechanical parts, the difficult road to research and development, and the field test are all "challenges" for the development of high-end machine tools in my country. The metal forming machine tool industry is a technology-intensive industry, and the development of the precision CNC machining industry requires a lot of technical input in various aspects. Judging from the companies that have performed well at present, most of them are large-scale enterprises with years of technology accumulation or state-owned or private enterprises that have entered the industry earlier and have strong technology research and development capabilities.
