Research And Development Direction Of The Future 5 Axis Turning And Milling Compound Center

5 Axis Turning And Milling Center


5-axis turning and milling techniques are typical of multi-axis machining techniques. The 5-axis turning and milling center is the vehicle for 5-axis turning and milling technology. It refers to the turning function and integrates functions such as milling and drilling, with at least three functions. Linear machine feed axis and two circumferential feed axes, and the name of the machine with an automatic tool changer. This combined turning and milling machining center is developed on the basis of the three-axis turning center. It is equivalent to a combination of a turning center and a machining center. It is a composite technology process developed in the 1990s, which is a mechanical design and manufacturing technology based on traditional technology, integrated with advanced control technology, advanced precision measurement technology and advanced machining CAD/CAM application technology.

The sophistication of the five-axis turning and milling center is reflected in its design philosophy. Usually the concept of machining, a piece is as small as one or two steps, and there are hundreds of processes. It is necessary to complete the machining of various equipment, prepare tools and accessories. For complex parts, it takes three to five months to prepare a set of tools. Even without considering the economic costs, it is likely that three to five months will lose many opportunities for commodities and strategic opportunities. Mechanical titanium is the main product of the company with superior turning, CNC machining of screw machining shafts, stem shafts and clamping columns. Automated production lines are widely used in mass-produced industries, such as automobiles and home appliances, to increase the level of efficiency and automation. The huge logistics system is a very important part of the automated production line. At the same time, part of its funding and land occupation, is also an integral part of the failure. For the handling of complex shapes, logistics is a big problem. Multiple fusing and comparative evaluation of parts sometimes leads to unnecessary processes and also to loss of machining accuracy. Centers for compound lathes and five-axis milling machines solve this problem from the design concept: it is a unique problem to complete all or most of the processing within the range of processing, and to jump from compound processing to complete processing.

The joint center for turning and milling five-axis machining has existed for nearly 20 years, and the technology has matured, which is well received and recognized by users at home and abroad.
From a trend point of view, it is mainly developing in the following directions:

1. Higher process range

Greater integration of the process is achieved by adding special function modules. For example, the machining of gears, internal and external grinding, deep hole machining, machining cavity, laser cooling, in-line measurement and other functions are integrated in the center of turning and milling to complete the truly complete processing of all complex parts.

2. Higher efficiency

Through the configuration of functions such as dual power heads, dual spindles, and dual tool holders, multiple blades can be processed at the same time to improve processing efficiency.

3. Large-scale

Since bulky, often complex parts require more parts and processes and require more time and are more difficult to install and position, a major advantage of turning and grinding is combined machining to reduce the number of processes and Multiple process copies. Adjustments and clamping times are re-installed multiple times, so it is advantageous to use turning and milling centers for compound machining. As a result, the current center of five-axis turning and milling mechanical compounds is being developed on a large scale. For example, turning and milling 5 HTM125 Shenyang machine tool series shafts with a diameter of 1250 mm and a length of 10,000 mm for turning, which is very suitable for turning and milling of large crankshaft engines for marine diesel.

4. Structural modularity and functions can be quickly reorganized

The rapid reorganization of the five-axis turning and milling center is an important condition for its ability to respond quickly to market demands and take advantage of the market. The modular structure is the basis for the rapid reorganization of the five-axis turning and milling center. Many products from some of the most advanced manufacturers have achieved structural modularity and are working towards a rapid reorganization of functionality.
The advanced concept of 5-axis turning and milling technology is to improve product quality and shorten product manufacturing cycle. Therefore, this technology has considerable advantages in military, aerospace, aerospace, marine and some civilian fields, especially in the machining of some parts with complex shapes in the aerospace industry. Therefore, foreign countries have entered the aerospace field. A large number of such equipment are used on site to replace traditional processing equipment, and the domestic industry is relatively backward in this regard. Therefore, it is necessary to learn from foreign advanced experience and strive to change the backward situation in the application field of five-axis turning and milling technology.
