1. Ultra-high speed and ultra-high precision machining technology

High-speed and ultra-high-speed machining technology not only improves machining efficiency, but also is an important guarantee for machining difficult materials, improving machining accuracy, and controlling vibration. The key to high-speed and ultra-high-speed machining technology is to increase the spindle speed and push speed of the machine. At the machining center (MC) exhibited at the fair, the maximum spindle speed reached 10,000 to 20,000 rpm, which doubled in just a few years. The maximum push speed is 20 to 60 meters per minute, which is several times that of the past.

The use of linear (magnetic levitation) motors is an important way to increase speed and accuracy. The linear motor-driven ultra-high-speed grinding machine "LineaMII" exhibited by Toyota Motor Corporation of Japan, the transmission part of the linear motor drive has no transmission factors such as connecting the screw and the nut, the connector of the motor and the screw, thus eliminating the The bending, vibration and rebound caused by the work performance have been improved by more than three times, meeting the requirements of high speed and high precision machining.

2, the trend of composite, multi-functional, multi-axis control

As information terminals are increasingly moving toward miniaturization and light weight, the processing requirements for their components are becoming higher and higher. As the level of component integration continues to increase and the number is reduced, the shape of the process is increasingly complex. Multi-axis controlled machines are suitable for machining complex shapes. On the other hand, the shortening of the product cycle also requires the machine tool to adjust and adapt to new changes at any time to meet the processing needs of a wide range of products. This requires a machine that can handle processes that previously required several machine tools.

In this context, the machining center (MC) can be said to adapt to the development trend of the times. The "NH5000 Series" machining center exhibited by Mori Seiki Co., Ltd. in Japan has realized automatic unmanned operation and can adapt to long-term, multi-variety and mass production. Compared with previous models, the processing time is greatly shortened, and the efficiency and output are improved.

Japan's Yamazaki Mazak's newly developed "INETGREX-E Series" multi-functional composite machining machine is capable of five-axis simultaneous machining. After one-time clamping of the workpiece, it can automatically complete a series of processes from turning to milling, quenching and grinding. One machine can complete the workload required by several machines in one operation, which not only improves efficiency, but also saves A large number of plant areas.

3. Application of information and communication technology

The introduction of information and communication technology has further improved the automation of modern machine tools. Operators can remotely modify the machine program through the network and mobile phones, monitor their operating conditions and accumulate relevant data.

With the globalization of the world economy, modern machine tools not only need to meet local needs in terms of after-sales service, but also must establish a global service system. Therefore, the network is used to connect manufacturers and users, and to repair equipment through the network. Inspection can not only improve the efficiency of after-sales service, but also help to improve the quality of products in a timely manner.

The "INETGREX-E series" multi-functional composite processing machine exhibited by Yamazaki Mazak Company of Japan at the meeting set up an E (electronic) operation tower with a fingerprint authentication system for operation and management personnel. The operation tower can observe the production. Process and give guidance to minimize idle non-production time; the “help” feature helps operators improve all machining operations. The machine can be connected to the mobile phone through the network. The mobile phone can display the current processing status, process and maintenance request prompts and other data, which can be described as the perfect combination of precision machine tools and information technology.
