Walking center machine - full name for walking center CNC lathe, also known as spindle box moving CNC automatic lathe, economical turning and milling composite machine tool, or longitudinal cutting lathe. Belonging to precision machining equipment, it can simultaneously complete composite processing such as turning, milling, drilling, boring, tapping, carving, etc., and is mainly used for batch processing of precision hardware and shaft shaped non-standard parts.
This machine tool originated in Germany and Switzerland and was mainly used for precision machining of military equipment in the early stage. With the continuous development and expansion of industrialization, it has gradually been applied in the processing of civilian products due to urgent market demand; The development of similar machine tools in Japan and South Korea was earlier than that in China, and in the early stages, they were mainly used in the military industry. After the war, with the increasing demand for development, they gradually became widely used in the manufacturing industry; Subsequently, Taiwan, China introduced this technology and independently developed this type of equipment with different processing needs. The manufacturing of CNC centrifugal machines in China started relatively late. Due to technological closure and policy restrictions, before the 1990s, China's centrifugal machines mainly relied on imports to meet processing needs. With the continuous development of automation and strong market demand, a large number of powerful CNC centrifugal machine manufacturers emerged in the Chinese market. Among them, this series of machine tools were produced in coastal areas such as Guangdong, Nanjing in Jiangsu, Shandong, Liaoning, and Xi'an in mainland China, and achieved good market applications, filling the domestic gap.
The centrifugal machine has made a qualitative leap in processing efficiency and accuracy compared to CNC lathes. Due to the use of dual axis arrangement of cutting tools, the processing cycle time is greatly reduced. By shortening the tool exchange time between the tool arrangement and the opposite tool table, multiple tool table overlap function, effective axis movement overlap function for thread chips, and direct spindle indexing function during secondary processing, the idle time is shortened. The chip cutting tool has always been machined at the clamping position between the spindle and the workpiece, ensuring constant machining accuracy. At present, the large machining diameter of the centrifuge on the market is 32mm, which has a great advantage in the precision shaft machining market. This series of machine tools can be equipped with automatic feeding devices to achieve fully automated production of a single machine tool, reducing labor costs and product defect rates. Very suitable for large-scale production of precision shaft parts.
Characteristic advantages:
1) Shorten the product manufacturing process chain and improve production efficiency. The combination of turning and milling can complete all or most of the processing steps in one clamping process, greatly shortening the product manufacturing process chain. On the one hand, this reduces the production auxiliary time caused by card loading changes, while also reducing the manufacturing cycle and waiting time of tooling and fixtures, which can significantly improve production efficiency.
2) Reduce clamping times and improve machining accuracy. The reduction in card loading frequency avoids the accumulation of errors caused by positioning benchmark conversion. At the same time, most of the turning and milling composite processing equipment has the function of online detection, which can achieve in situ detection and accuracy control of key data in the manufacturing process, thereby improving the machining accuracy of the product.
3) Reduce land area and lower production costs. Although the single unit price of turning and milling composite 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 investment in fixed assets, production operation, and management costs.
Design features:
Due to its different structure from traditional CNC lathes, the machining efficiency and accuracy of the centrifuge are higher than those of CNC lathes. The walking machine adopts a dual axis arrangement of cutting tools, which greatly saves processing cycle time. By shortening the tool exchange time between the tool arrangement and the opposite tool table, it achieves the functions of multiple tool table overlap and effective axis movement overlap of thread chips. The direct spindle indexing function during secondary processing shortens the actual empty walking time. In the machining process of the clamping part between the spindle and the workpiece, the chip cutting tool has always played a very important role, providing a strong guarantee for constant machining accuracy. From the perspective of the centrifuge market, 32mm is its machining diameter, which gives the centrifuge a significant advantage in the precision shaft machining market. This series of machine tools can also be equipped with automatic feeding devices, achieving fully automated production of a single machine tool, reducing labor costs and defective products in the production process. It can be used to produce large quantities of precision shaft parts.
