What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

The main shortcomings of the four-roll calendering method in the production of inner lining

At the same time, the airtight layer film to be used on the guiding device is guided and enters the centering compound platform through the film conveyor belt. On the centering compound platform, the airtight layer film and the transition layer film are combined to form an inner lining. . The composite inner lining layer enters the winding device through the film conveyor belt for winding, and the hard polyester film is put on the winding. Similarly, the winding temperature is lower than 40 ℃, and the inner lining film is rolled on an I-shaped reel. At this point, the inner liner is produced and enters the forming process for use. Main technical parameters The main technical parameters of the four-roll calendering method for the production of inner lining are as follows; calender power 4×40kW; single-layer film thickness 0.4~3.0mm; film width composite centering error ≤ 2mm; film winding uniformity error. Main advantages and disadvantages The advantages of the four-roll calendering method to produce the lining layer are mainly manifested in the following aspects: (1) faster production speed; (2) better surface quality of the produced film; (3) lower temperature of the rubber compound; ( 4) Lower equipment investment.

The four-roll calendering method mainly has the following shortcomings in the production of inner lining: (1) Since the rubber material fed into the roller gap of the calender is a reciprocating rubber strip, the rubber material has a certain amount of accumulation on the roller gap. The accumulated rubber is rolled into the nip for several times before being rolled, so it is easy to entrap air and make the rolled film contain air bubbles. (2) Because it is easy to form bubbles, the calendering method is only suitable for calendering to produce films that are not too thick. Generally, the thickness of the calendered film is not more than 3mm. For thick products (such as transition layer film), only the pasting method can be used. Production. (3) Since the roller of the four-roll calender is of no belt type and adopts the layered method, the cross-sectional shape of the inner lining produced by the calendering method can only approximately meet the structural design requirements. (4) The thickness error of the film is affected by the amount of accumulated glue. Therefore, the feeding should be carried out continuously and evenly to keep the amount of accumulated glue constant.
