Origin and development of Centering type CNC lathe

2023-07-03

Centering machine first originated in Swit zerland and Germany, the first mainly used for military instruments precision processing, with the continuous development and expansion of industrialization process, due to the urgent needs of the market, gradually applied to the processing of civilian products; Japan and South Korea, the development of similar machine tools earlier than China, the early mainly focused on the use of the military field, after the war with the development of demand gradually in the manufacturing industry widely used; then Taiwan, China introduced The technology, and independent research and development of different processing needs of the type of equipment.

China's centering machine manufacturing started late, due to the closure of technology and policy restrictions, China's centering machine before the 1990s mainly rely on imports to meet processing needs, with the continuous development of automation and strong market demand, the Chinese market has emerged a large number of strong CNC centering machine manufacturers, including in coastal Guangdong, Jiangsu Nanjing, Shandong, Liaoning, the mainland Xi'an have the series of machine tools Production, and has made a good market application, filling the domestic blank.

Centering machine in the processing efficiency and processing accuracy than the CNC lathe has a qualitative leap, due to the use of two-axis arrangement of tools, greatly reducing the processing cycle time, by shortening the row of tools and the opposite tool table tool exchange time, multiple tool table overlap function, thread chip effective axis movement overlap function, the second processing of the direct spindle indexing function, to achieve the shortening of the empty walk time. The chip tool has been processed in the spindle and workpiece clamping part, to ensure that the processing accuracy is constant and unchanged The maximum processing diameter of the centering machine in 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 device to achieve fully automated production of a single machine tool, reducing labor costs and product defect rate. It is very suitable for high volume production of precision shaft parts.
