Professional CNC precision machining

The advantages and benefits of CNC milling machines should be fully carried forward when selecting CNC milling machine parts for processing. On the surface, for the machining parts of precision mechanical parts with complex shapes, various sizes, and difficult scribing and inspection, CNC milling machines are divided into three categories according to the difference in the position of their spindles: vertical, horizontal, and vertical-horizontal dual-purpose milling machines. The difference in the spindle position is divided into three categories: vertical, horizontal, vertical and horizontal dual-use, and gantry processing.

The reason why the machining of precision parts is called precision machining is because its machining procedures and machining requirements are very high, and the precision requirements of the products are also very high, and the machining accuracy of precision parts includes: position accuracy, size Accuracy, shape accuracy, etc., based on the company's more than ten years of manufacturing and processing history, summarize the following components that affect the accuracy of precision parts: 1. During the process of precision parts processing and cutting, the system will be deformed due to the change of the position of the force point. Differences will be caused, and errors of different degrees will also be caused in processing. 2. Use the imitation flashing function that comes with CNC machining. Generally, the more advanced CNC machining has a graphic flashing function. 3. Use the dry running function in the CNC machining. 4. Use the locking function in the CNC machining. Ordinary CNC There is a locking function in the middle of processing. After entering the program, lock the Z axis, and you can identify whether there will be a collision through the coordinate value of the Z axis. The application of this function should avoid operations such as tool change, otherwise the program cannot be passed.

Processed materials: aluminum alloy, stainless steel, magnesium alloy, titanium alloy, nickel Base alloys (invar alloys/invar alloys, kovar alloys/kovar alloys), superalloys, tungsten-copper alloys, engineering plastics and other materials that are particularly difficult to process.

Processed products: precision mechanical parts, medical precision parts, aviation parts, instrumentation parts, optical fiber communication parts, electronic product parts, auto parts, shock absorbers, suspension parts, High-standard products in non-standard components, connectors, alloy parts, hardware shells, radiators and other industries.

Have you learned these clamping techniques for precision parts processing? According to the characteristics of positioning, there are generally three clamping techniques for precision parts processing: simply find the correct method, plan to find the correct method and fixture clamping method, simply Finding the correct method: simply finding the correct method is to instigate the use of a dial indicator, a drawing needle or a visual inspection to simply find the design datum of the workpiece machining surface on the machine tool to obtain the precise position, such as sleeve parts, in order to ensure that there are For a well-proportioned machining allowance, please clamp the sleeve in the four-jaw single-action chuck in advance, and then use the pointer or dial indicator to align the surface of the inner hole, so that the axis is coaxial with the machine tool to twist the middle, and then clamp. Tighten the workpiece.

This is because this process can only achieve high material removal rates by supplying a large amount of energy. On the other hand, there are still doubts about whether the machined workpiece can meet the dimensional and shape accuracy requirements, no chip pressure. Processing is mainly used for batch manufacturing, and usually requires subsequent cutting to obtain a qualified workpiece shape, especially with the development trend of small-scale manufacturing, the requirements for the shape and dimensional accuracy of the workpiece are getting higher and higher, which is the development of precision parts processing. A new, wider platform.
