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
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 .

Five-axis processing of plastic parts is a more commonly used form of processing now. It can process complex-shaped parts that ordinary machine tools cannot process. However, when using five-axis processing, you also need to master the corresponding technology, otherwise you will be processing complex parts. Quality problems are prone to occur when
1. Compile the tool program
Table of Contents
Although the tool length compensation function in five-axis machining is still effective, the tool radius compensation is invalid. This is because the ISO file does not provide enough data to recalculate the tool position. Therefore, in order to ensure reliable machining quality, it is necessary to compile different programs for different diameters of the tool when performing five-axis machining.
2. Use post processor
The difference between five-axis and three-axis machine tools is that there are two rotating coordinates on the five-axis machine tool and the tool position is converted from the workpiece coordinate system to the machine tool coordinate system, and the coordinates need to be changed several times in the middle. With the help of the current popular post processor generator, the post processor of a three-axis Cnc Machine tool can be generated only by inputting the basic parameters of the machine tool. For five-axis CNC machine tools, there are currently only some improved post-processors and the post-processors of five-axis CNC machine tools need to be further developed.
3. Solve the problem of nonlinear error and singularity
The kinematics of five-axis machining after the introduction of rotating coordinates is much more complicated than that of three-axis machine tools. One of the main problems related to rotation is the nonlinear error and it belongs to the programming error. In order to avoid this error, the programmer cannot know the size of the nonlinear error in the pre-calculation stage. Only after the machine tool program is generated by the post processor, the nonlinear error It is possible to calculate the error.
Although five-axis machining has more advantages than ordinary machining methods, in order to avoid the inefficiency of the entire machining process and the unsatisfactory quality of the machining, when using the five-axis machining of plastic parts, everyone should program the tool first. After that, we must make good use of post-processors and solve problems such as non-linear errors.
