Although the unit price of the turning and milling complex processing equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of the equipment required for the product, as well as the reduction in the number of tooling fixtures, workshop footprint and equipment maintenance costs, it can effectively reduce the overall fixed assets The cost of investment, production operation and management.
Swiss machine, which is called the centering type CNC lathe, can also be called the spindle box mobile CNC automatic lathe, economical turning and milling machine tool or slitting lathe. It belongs to precision processing equipment, which can complete the composite swiss machining of turning, milling, drilling, boring, tapping, and engraving at the same time. It is mainly used for batch processing of precision hardware and shaft shaped non-standard parts.
The machine tool first originated in Germany and Switzerland. It 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 demand 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 field of military industry in the early days. After the war, the demand for development was gradually widely used in the manufacturing industry; subsequently, Taiwan China introduced the technology and independently developed this type of equipment for different processing needs. With the continuous development of automation and the strong demand of the market, a large number of powerful CNC Swiss machine manufacturers have gradually appeared, including the production of this series of machine tools in coastal Guangdong, Nanjing, Jiangsu, Shandong, Liaoning and Xi’an, And achieved good market application.
Swiss machine has a qualitative leap in machining efficiency and machining accuracy compared to CNC lathes. Due to the use of dual-axis arrangement tools, the processing cycle time is greatly reduced. By shortening the tool exchange time between the arrangement tool and the opposite tool table, multiple tools Table overlap function, thread chip effective axis movement overlap function, direct spindle indexing function during secondary machining, realize the reduction of idle time. The chip cutting tool is always processed in the clamping part of the spindle and the workpiece, ensuring that the processing accuracy is constant. At present, the maximum processing diameter of Swiss machine on the market is 32mm, which has a great advantage in the precision shaft processing market. This series of machine tools can be equipped with an automatic feeding device to realize the fully automated production of a single machine tool, reducing labor costs and product defect rates. Very suitable for mass production of precision shaft parts.
Features and advantages:
1) Shorten the product manufacturing process chain and improve production efficiency. Turning and milling composite processing can realize all or most of the processing procedures in one loading, thus greatly shortening the product manufacturing process chain. In this way, on the one hand, the production auxiliary time due to the change of the installation card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling fixture are reduced, and the production efficiency can be significantly improved.
2) Reduce the number of clamping times and improve the processing accuracy. The reduction in the number of card installations avoids the accumulation of errors caused by the conversion of the positioning reference. At the same time, most of the turning and 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 accuracy of the product.
3) Reduce floor space and production costs. Although the unit price of the turning and milling complex cnc machining equipment is relatively high, due to the shortening of the manufacturing process chain and the reduction of the equipment required for the product, as well as the reduction in the number of tooling fixtures, workshop footprint and equipment maintenance costs, it can effectively reduce the overall fixed assets The cost of investment, production operation and management.
Because the structure of the Swiss machine is different from the traditional CNC lathe, the processing efficiency and precision of the Swiss machine are higher than that of the CNC lathe. Swiss machine adopts dual-axis arrangement of tools. This design greatly saves the processing cycle time. By shortening the tool exchange time between the arrangement tool and the opposed tool table, the multiple tool table overlap and the effective axis movement overlap function of thread cuttings are realized. , The direct spindle indexing function during secondary processing shortens the real empty running time. In the machining process of the spindle and workpiece clamping part, the chip tool has always played a very important role, which provides a strong guarantee for constant processing accuracy. As far as the Swiss machine market is concerned, 32mm is its largest processing diameter, which makes Swiss machine a great advantage in the precision shaft processing market. This series of machine tools can also be equipped with automatic feeding devices to realize the fully automated production of a single machine tool, reducing labor costs and bad products in the production process, and can be used to produce large quantities of precision shaft parts.
