CNC Knowledge: There is a kind of trick called a trick!

Centering machine – full name is centering CNC lathe. It can also be called moving spindle box CNC automatic lathe, economical turn-mill machine tool or slitting lathe. It is a precision processing equipment that can simultaneously carry out turning, milling, drilling, reaming, tapping, engraving and other complex processing. It is mainly used for batch processing of precision hardware and special-shaped non-standard parts such as shafts. .

This machine tool originates from Germany and Switzerland. At first, it was mainly used for precision processing of military equipment. With the continuous development and expansion of the industrialization process and the urgent market demand, it has been gradually used around the world. processing of civilian products; development of similar machine tools in Japan and South Korea. Before China, it was mainly used in the early military industry. With the development needs after the war, it was gradually widely used in the manufacturing industry. Later, Taiwan, China introduced this technology and independently developed this type of equipment for different processing needs.

The manufacturing of basic machines in China started late. Due to closed technology and policy restrictions, before the 1990s, China’s core machinery mainly relied on imports to meet processing needs. With the continuous development of automation and strong market demand, the Chinese market has become a large market. A number of powerful CNC machine tool manufacturers produce this series of machine tools in coastal Guangdong, Jiangsu, Nanjing, Shandong, Liaoning and inland Xi’an. They have obtained good applications in the market and filled the national gap.

CNC lathes have made a qualitative leap in processing efficiency and precision compared to CNC lathes. Through the use of a biaxial tool arrangement, the processing cycle time is significantly reduced by shortening the tool exchange time between the tool row and the opposing tool. table, multiple tools can be table overlap function, effective axis movement overlap function of threading chip and direct spindle indexing function during secondary processing can shorten idle time. The chip cutter tool is always processed at the clamping position between the spindle and the workpiece, ensuring consistent processing accuracy. At present, the maximum processing diameter of the centering machine on the market is 32mm, which has great advantages in the precision shaft processing market. This series of machine tools can be equipped with an automatic feeding device to realize fully automated production of a single machine tool, thereby reducing labor costs and product defect rates. It is very suitable for mass production of precision shaft parts.

Features and Benefits:

1) Shorten the product manufacturing process chain and improve production efficiency. The combined processing of turning and milling can complete all or most of the processing steps in a single facility, thereby greatly shortening the product manufacturing process chain. This not only reduces the production auxiliary time caused by changes in the installation of accessories, but also reduces the manufacturing cycle of tooling accessories and waiting time, which can greatly improve production efficiency. .

2) Reduce the number of clamping times and improve processing accuracy. Reducing the number of card installations avoids the accumulation of errors caused by positioning reference conversion. At the same time, most composite turning and milling processing equipment has online detection functions, which can realize on-site detection and precise control of key data in the manufacturing process, thereby improving accuracy processing of the product.

3) Reduce floor space and production costs. Although the single unit price of composite turning and milling 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 accessories, workshop floor space and equipment maintenance costs, it can effectively reduce the overall fixed asset investment, production operations and management costs.

Design features:

Since the structure of the centering machine is different from that of the traditional CNC lathe, the processing efficiency and precision of the centering machine are higher than that of the CNC lathe. The centering machine uses a biaxial arrangement of tools. This design significantly saves processing cycle time. By shortening the tool exchange time between the tool arrangement and the opposite tool station, it realizes the overlap of multiple tool stations and the effective overlap of the thread axis movement. chips, the direct spindle indexing function during secondary processing shortens the actual no-load travel time.

In the machining process of the clamping part of the spindle and the workpiece, the chip tool has always played a very important role, which provides a strong guarantee of consistent machining accuracy. Regarding the core machine market, 32mm is its maximum processing diameter, which gives the core machine 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 automated production of a single machine tool, thereby reducing labor costs and defective products during the production process. production, and can be used to produce large quantities of precision shaft parts.
