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

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

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 .

Three commonly used compensation methods for CNC machining and mold machining

1. CNC machining tool length compensation

The concept of tool length is an important concept. When programming a part, the programming center of the part must be specified first, and then the workpiece programming coordinate system can be established. It is just a workpiece coordinate system, and the zero point is generally on the workpiece. The length compensation of CNC machining is only related to the Z coordinate. It is not like the programmed zero point on the X and Y planes, because the tool is positioned by the spindle taper hole without changing, and the zero point of the Z coordinate is different. The length of each knife is different, for example, we have to drill a hole with a depth of 50 mm, and then click the tap with a depth of 45 mm, which has 250 mm and 350 mm taps respectively. At this time mm, the machine tool has set the workpiece zero point. When the mold processing is changed to tap tapping, if both tools are processed from the set zero point, the tap is too long, because it is longer than the drill, which will damage the tool and the workpiece.

2. Tool radius compensation

  • The concept of tool radius and compensation is just like using different tool path lengths as compensation. Basically, you don’t need to consider choosing the length of the tool yourself when programming. Because of the tool radius compensation, we can do it at the same time when programming. Did not consider too much tool diameter size. CNC machining tool length compensation is applicable to all tools, while tool radius compensation is generally only used for milling cutters.
  • Offset compensation: When the machining center is processing small workpieces, the fixture can accommodate multiple workpieces at a time. The programmer does not need to consider the zero point of each workpiece coordinate when programming, but program according to the respective programmed zero point, and then Use the fixture offset of CNC machining to move the programmed zero point on each workpiece of the machine tool. Just as tool length compensation and radius compensation allow programmers to cover tool length and size, fixture offset allows programmers to use fixture offsets regardless of the location of the workpiece fixture.
