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

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

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.
