Development of five-axis machining technology

                             Development of five-axis machining technology
       Five-axis machining technology is a typical multi-axis machining technology. The five-axis machining center is the carrier of five-axis machining technology. It refers to a kind of turning function-based and integrated milling and boring milling functions. It has at least 3 straight lines. A general term for machine tools equipped with feed and 2 circumferential feed axes and equipped with an automatic tool change system. This machining composite machining center is developed on the basis of a three-axis turning center, which is equivalent to a combination of a turning center and a machining center. It is a composite machining technology developed in the 1990s and is a traditional mechanical design. In terms of precision manufacturing technology, it integrates modern advanced control technology, precision measurement technology CAD/CAM application technology and advanced machining technology.

     The advanced nature of the five-axis machining center is manifested in its design concept. In the usual mechanical processing concept, the processing of one part can be completed by at least one or two procedures, and as many as hundreds of procedures, which must be processed by multiple equipment. , To prepare knives, tooling fixtures. For complex parts, it takes three to five months to prepare a set of tooling. Even if economic costs are not considered, three to five months are likely to miss many commodity opportunities and strategic opportunities. In mass production industries such as automobiless and home appliances, automated production lines are widely used in order to improve efficiency and automation. The huge logistics system constitutes a very important part of the automatic line. At the same time, it is a busy and land-occupying part, and it is also a part with frequent failures. For the processing of complex shapes, logistics is a big problem. The multiple clamping and datum conversion of parts sometimes bring unnecessary processes and at the same time cause the loss of parts processing accuracy. The five-axis machining compound machining center solves this problem from the design concept. It is a one-time clamping, completing all or most of the processes in the processing range, and realizing the leap from compound processing to complete processing.

       The five-axis machining compound machining center has a history of nearly 20 years since its production. The technology has matured and is accepted and recognized by users at home and abroad. From the trend point of view, it mainly develops in the following directions.

Higher process range: through the addition of special function modules, more process integration can be achieved. For example, integrating gear processing, internal and external grinding processing, deep hole processing, cavity processing, laser quenching, online and other functions into the machining center, truly complete processing of all complex parts.

Higher efficiency: Through the configuration of dual power heads, dual tool holders and other functions, multiple tools can be processed at the same time to improve processing efficiency.

Large-scale: Because large-scale parts are generally complicated in structure, require more processing parts and procedures, and installation and positioning are also time-consuming and troublesome. One of the main advantages of processing composite is to reduce the number of parts in the multi-process and multi-process processing process. Many times of re-installation adjustment and tightening time, so it is more advantageous to use a machining center for compound processing. Therefore, the current five-axis machining compound machining center is developing towards large-scale development.

Structural modules and functions can be quickly reorganized: The rapid reorganization of the functions of the five-axis machining center is an important condition for its ability to quickly respond to market demand and seize the market, and the structural modules are the basis for the rapid reorganization of the functions of the five-axis machining center. Many products of some technologically advanced manufacturers are designed to achieve structural modularization, and are working hard on how to achieve rapid functional reorganization.

      The advanced concept of five-axis machining technology is to improve product quality and shorten product manufacturing cycles. Therefore, this technology has considerable advantages in military, aerospace, aviation, shipbuilding and some civil industrial applications, especially in the processing of special-shaped parts with complex shapes in the aerospace field. Therefore, it has already been used in aerospace abroad. In the aviation field, a large number of such equipment is used to replace traditional processing equipment, and the domestic is relatively backward in this regard, so it is necessary to learn from the advanced experience of foreign countries to strive to change the backward situation in the application of five-axis processing technology.
