What is CNC PRECISION AUTOMATIC LATHE/Swiss -type Automatic Lathe?

CNC precision automatic lathe — the full name of the walking CNC lathe, can also be called Swiss-type automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound processing such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch processing of precision hardware and special-shaped non-standard shaft parts.

Swiss-type Automatic Lathe
This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of the industrialization process, due to the urgent needs of the market, it was gradually applied to 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 widely used in the manufacturing industry with the needs of development; then Taiwan, China introduced this technology and independently developed this type of equipment for different processing needs.

China’s Swiss-type automatic lathe manufacturing started relatively late. Due to technical closure and policy restrictions, before the 1990s, China’s Swiss-type automatic lathe mainly relied on imports to meet processing needs. With the continuous development of automation and the strong market demand, the Chinese market has emerged. A large number of powerful CNC machine tool manufacturers, including Guangdong, Jiangsu, Nanjing, Shandong, Liaoning, and mainland Xi’an, have produced this series of machine tools, and have achieved good market applications, filling the domestic gap.

Compared with CNC lathes, the machine has a qualitative leap in processing efficiency and processing accuracy. Due to the use of two-axis arrangement of tools, the processing cycle time is greatly reduced. The table overlap function, the thread chip effective axis movement overlap function, and the direct spindle indexing function during secondary machining can shorten the idle time. The chip tool has always been processed in the spindle and the work piece clamping part, which ensures the constant processing accuracy. This series of machine tools can be equipped with an automatic feeding device to realize fully automatic production of a single machine tool and reduce labor costs and product defect rates. It is very suitable for mass production of precision shaft parts.

Features and Advantages
Compared with the conventional CNC machining process, the outstanding advantages of composite machining are mainly reflected in the following aspects:

1.Shorten the product manufacturing process chain and improve production efficiency. Turn-milling composite machining can realize all or most of the machining processes in one loading, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production auxiliary time caused by the change of the loading card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling and fixture are also reduced, which can significantly improve the production efficiency.

2.Reduce the number of clamping and improve the machining accuracy. The reduction in the number of card loading avoids the accumulation of errors due to positioning fiduciary conversions. At the same time, most of the turning-milling composite processing equipment has the function of online detection, which can realize the in-situ detection and precision control of key data in the manufacturing process, thereby improving the processing precision of products.

3.Reduce floor space and lower production costs. Although the price of a single turn-milling compound processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of equipment required for the product, as well as the reduction of the number of fixtures, workshop area and equipment maintenance costs, it can effectively reduce the overall fixed assets. The cost of investment, production operation and management.

Origin and Development
Swiss-type automatic lathe machine first originated in Switzerland and Germany. At that time, the Swiss-type automatic lathe machine was used for precise processing of military equipment. Later, with the continuous development of the industry, the market demand for the Swiss-type automatic lathe machine was increasing, and Swiss-type automatic lathe machine was gradually used in the processing of civilian products. Compared with similar machine tools in Japan and South Korea, China developed relatively late, and after the war, the Swiss-type automatic lathe machine was widely used in the manufacturing industry; then Taiwan, China introduced this technology, and independently developed different types of Swiss-type automatic lathe machine in order to meet different processing needs.

The closure of technology and the restriction of policies are the main reasons for the backwardness of the manufacturing of China’s moving machines. Before the 1990s, China needed to rely on imported foreign Swiss-type automatic lathe machine to meet the needs of industrial processing. Due to the urgency and demand of the domestic market, a large number of powerful Swiss-type automatic lathe machine manufacturers have emerged in China, among which the main manufacturing areas are: Guangdong, Zhejiang, Jiangsu, Zouping in Shandong, Liaoning and Xi’an. The emergence of these machine manufacturers has met the needs of the Chinese machine market.

Design Features
Since the structure of the Swiss-type automatic lathe machine is different from that of the traditional CNC lathe, the processing efficiency and machining accuracy of the Swiss-type automatic lathe machine are higher than those of the CNC lathe. The machine adopts two-axis arrangement of tools. This design greatly saves the processing cycle time. By shortening the tool exchange time between the arrangement of tools and the opposite tool table, the overlapping functions of multiple tool tables and effective axis movement of thread chips are realized. , The direct spindle indexing function during the secondary processing shortens the actual and empty travel time.

In the machining process of the spindle and the work piece clamping part, the chip tool has always played a very important role, which provides a strong guarantee for constant machining accuracy. As far as the centering machine market is concerned, 38mm is its maximum processing diameter, which makes the centering machine have a great advantage in the precision shaft processing market. This series of machine tools can also be equipped with an automatic feeding device to realize fully automatic 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.

As a leading manufacturer of industrial lathe machinery and machine tools in China, Shanghai ANTS has 20 years of experience in machine tool production. A wide range of products, including grinding machines, lathes, milling machines, Planing machine & Slotting machine, sawing machines, drilling machines, etc., can meet the needs of all walks of life, and are widely used in defense aviation, automobile industry, mold manufacturing, machining, parts processing and other industries.
