Centering machine – the full name of the centering CNC lathe can also be called spindle box mobile CNC automatic lathe, economic turning and milling compound machine tools, or longitudinal cutting lathe. It belongs to the precision processing equipment, which can complete the compound processing of turning, milling, drilling, boring, tapping, and engraving at the same time, mainly used for the batch processing of precision hardware and shaped non-standard parts of the shaft.

The centering machine has a qualitative leap in processing efficiency and processing accuracy than the CNC lathe, due to the use of the two-axis arrangement of tools, greatly reducing the processing cycle time, by shortening the tool exchange time between the row of tools and the opposite tool table, 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 walking time. The cutting tool is always machined on the spindle and workpiece clamping area, ensuring constant machining accuracy.

The maximum machining diameter of the centering machines currently on the market is 32 mm, which is a great advantage in the market of precision shaft machining. This series of machines can be equipped with automatic feeding devices to achieve fully automated production of a single machine, reducing labor costs and product defect rates. Ideal for high volume production of precision shaft components.

Feature advantages.
(1) Shorten the product manufacturing process chain and improve production efficiency. Turning and milling can complete all or most of the machining processes in one set-up, thus greatly reducing the manufacturing process chain. This reduces the time required for production assistance due to changes in the clamping, and also reduces the cycle time and waiting time for the manufacture of tooling and fixtures, which significantly improves production efficiency.
(2) Reduce the number of clamping operations and improve machining accuracy. The reduction in the number of clamping times avoids the accumulation of errors due to the transformation of the positioning datum. At the same time, most of the turning and milling machines have the function of online inspection, which can realize the in-situ inspection and accuracy control of key data in the manufacturing process, thus improving the machining accuracy of products.
(3) Reduce floor space and production costs. Although the single unit price of turn-mill machining equipment is relatively high, it can effectively reduce the overall investment in fixed assets, production operation, and management costs 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 fixtures and jigs, workshop floor space and equipment maintenance costs.

Design features.

As the structure of the centering machine is different from the traditional CNC lathe, the processing efficiency and processing accuracy of the centering machine are higher than that of the CNC lathe. The centering machine uses a two-axis tool arrangement, this design substantially saves the machining cycle time, by shortening the tool exchange time between the row of tools and the opposite tool table method, to achieve multiple tool table overlap and thread chip effective axis movement overlap function, the secondary processing of the direct spindle indexing function, shorten the real empty walking time.

The cutting tool has always played a very important role in the machining process of the spindle and workpiece clamping part, which provides a strong guarantee for constant machining accuracy. For the centering machine market, 32 mm is the maximum diameter that can be machined, which gives the centering machine a significant advantage in the market for precision shaft machining. This series of machines can also be equipped with automatic feeding devices for fully automated production on a single machine, reducing labor costs and defective products during production, and can be used to produce large quantities of precision shaft parts.
