Swiss Machine-the full name is the spindle-type CNC lathe, it can also be called the headstock mobile CNC automatic lathe, the economical turning-milling compound machine tool or the slitting lathe. It is a precision processing equipment that can complete lathe, milling, drilling, boring, tapping, engraving and other compound processing at one time. It is mainly used for batch processing of precision hardware and shaft special-shaped non-standard parts.
CNC Swiss Machine
The machine tool first originated in Germany and Switzerland, and was mainly used for precision processing of military equipment in the early stage. With the continuous development and expansion of the industrialization process, due to the urgent needs of the market, it is gradually used in the processing of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually used in the manufacturing industry with the development of the demand. Later, China Taiwan introduced this technology and independently developed this type of equipment for different processing needs.
The manufacture of Swiss Machine in China started late. Due to technical closure and policy restrictions, before the 1990s, Swiss Machine in China mainly relied on imports to meet processing needs. With the continuous development of automation and strong market demand, the Chinese market emerged A large number of powerful CNC Swiss Machine manufacturers, among them, have produced this series of machine tools in coastal Guangdong, Jiangsu Nanjing, Shandong, Liaoning, and inland Xi’an. They have achieved good market applications and filled the domestic gap.
Swiss Machine has a qualitative leap in machining efficiency and machining accuracy compared to CNC lathes. Thanks to the dual-axis arrangement of tools, the machining cycle time is greatly reduced. By shortening the tool exchange time between the gang tool and the opposed tool station, multiple tools Table overlap function, effective axis movement overlap function of thread chip, direct spindle indexing function during secondary processing, realize the shortening of idling time. The chip cutting tool is always processed in the clamping part of the spindle and the workpiece to ensure the constant accuracy of the processing. The maximum processing diameter of the Swiss Machine on the market is 38mm, which has a great advantage in the precision shaft processing market. This series of machine tools can be equipped with automatic feeding devices to realize fully automated production of a single machine tool, reducing labor costs and product defect rates. It is very suitable for mass production of precision shaft parts.
Features and advantages
Compared with conventional Cnc Machining technology, the outstanding advantages of compound machining are mainly manifested in the following aspects:
- Shorten the product manufacturing process chain and improve production efficiency. Turning and milling combined processing can complete all or most of the processing procedures at one time, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production assistance time caused by the change of the installation card is reduced, and the manufacturing cycle and waiting time of the tooling fixture are also reduced, which can significantly improve the production efficiency.
- Reduce the number of clamping and improve processing accuracy. The reduction in the number of card loading avoids the accumulation of errors due to the conversion of positioning benchmarks. At the same time, most of the turning-milling composite processing equipment has the function of online detection, which can realize the in-position detection and precision control of key data in the manufacturing process, thereby improving the processing accuracy of the product.
- Reduce floor space and production cost. Although the price of a single unit of turning-milling composite processing equipment is relatively high, the overall fixed assets can be effectively reduced due to the shortening of the manufacturing process chain and the reduction of equipment required for products, as well as the reduction in the number of fixtures, workshop area and equipment maintenance costs. The cost of investment, production operation and management.
Origin and development
Swiss Machine originated in Switzerland and Germany. At that time, the Swiss Machine was used for precise processing of military equipment. Later, with the continuous development of the industry, the market demand for the Swiss Machine was increasing, and the Swiss Machine was gradually used in the processing of civilian products. Compared with similar machine tools in Japan and South Korea, China developed late. After the war, Swiss Machine was widely used in the manufacturing industry. Then Taiwan introduced the technology and independently developed different types of Swiss Machine to meet different processing needs.
Technology closure and policy restrictions are the main reasons that led to the backward manufacturing of Swiss Machines in China. Before the 1990s, China had to rely on imported Swiss Machines to meet the needs of industrial processing. Due to the urgency and demand of the domestic market, a large number of powerful Swiss Machine manufacturers have emerged in China. The main manufacturing areas are: Guangdong, Zhejiang, Jiangsu, Zouping, Liaoning and Xi’an in Shandong. The emergence of these Swiss Machine manufacturers meets the needs of the Chinese Swiss Machine market.
Because the structure of Swiss Machine is different from traditional CNC lathes, the machining efficiency and machining accuracy of Swiss Machine are higher than those of CNC lathes. Swiss Machine adopts two-axis arrangement of tools. This design greatly saves the machining cycle time. By shortening the tool exchange time between the gang tool and the opposed tool station, the function of multiple tool station overlap and thread chip effective axis movement overlap function is realized. , Direct spindle indexing function during secondary processing, shorten the actual idle time.
In the machining process of the spindle and the clamping part of the workpiece, the chip cutting tool has always played a very important role, and it provides a strong guarantee for the constant machining accuracy. As far as the Swiss Machine market is concerned, 38mm is its largest machining diameter, which gives Swiss Machine a great advantage in the precision shaft machining market. This series of machine tools can also be equipped with automatic feeding devices to realize fully automated production of a single machine tool, reducing labor costs and defective products in the production process, and can be used to produce large quantities of precision shaft parts.
