The research and development direction of the future five-axis turning and milling center

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

The advanced nature of the five-axis turning and milling center is reflected in its design philosophy. Usually the concept of processing, a piece is used as one or two steps, and there are hundreds of processes. It is necessary to complete the processing of various equipment and prepare tools and accessories. For complex parts, it takes three to five months to prepare a set of tools. Even without considering economic costs, it is likely that three to five months will lose many opportunities for commodities and strategic opportunities. Mechanical titanium is the company’s main product with superior rotation, CNC machining of screw machining shafts, stem shafts and clamping columns. In large-scale production industries, such as automobiles and household appliances, to improve efficiency and level of automation, automated production lines are widely used.

The huge logistics system is a very important part of the automated production line. At the same time, part of its capital and occupied land is also a component of failure. For the processing of complex shapes, logistics is a big problem. Multiple fixing and comparative evaluation of components sometimes leads to unnecessary processes and also leads to loss of processing accuracy. The center of compound lathe machining and five-axis milling machine solves this problem from the design concept: it is a unique problem that completes all or most of the processing within the processing range, and jumps from the composite processing to complete advance cnc machining.

There has been a joint center for turning and milling five-axis machining for nearly 20 years. The technology has matured and is well received and recognized by users at home and abroad.
From a trend perspective, it mainly develops in the following directions:

1. Higher process range

By adding special function modules to achieve greater integration of the process. For example, gear, internal and external grinding, deep hole machining, machining cavity, laser cooling, on-line measurement and other functions are integrated in the turning and milling center to complete the complete and complete processing of all complex parts.

2. Higher efficiency

Through the configuration of dual power heads, dual spindles, dual tool holders, etc., multiple blades can be processed simultaneously, improving processing efficiency.

3. Large-scale

Because large pieces of usually complex parts require more components and processes, and require more time and are more difficult to install and position, a major advantage of rotation and grinding is combined mechanical processing to reduce in multiple processes and There are multiple processes. The adjustment and clamping times are reinstalled multiple times, so it is advantageous to use turning and milling centers for compound machining. Therefore, the current center of five-axis turning and milling mechanical compounds is currently being developed on a large scale. For example, turning and milling the diameter of the center of five HTM125 Shenyang machine tool series shafts is 1250 mm in diameter and 10,000 mm in length, which is very suitable for turning and milling marine diesel for large crankshaft engines.

4. Modular structure 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 use the market. The modular structure is the basis for the rapid reorganization of five-axis turning and milling centers. Many of the products of some of the most advanced manufacturers have already realized the modular design of the structure, and are working hard to realize the rapid reorganization of functions.

The advanced concept of five-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 civil fields, especially in the processing of some components with complex shapes in the aerospace industry. Therefore, foreign countries have entered the field of aerospace. A large amount of such equipment is used on site to replace traditional processing equipment, and the domestic industry is relatively backward in this respect. 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.
