Because the structure of the walking machine is different from the traditional CNC lathe, the machining efficiency and machining accuracy of the walking machine are higher than that of the CNC lathe. The walking machine adopts the double-axis arrangement tool. This design greatly saves the machining cycle time. By shortening the tool exchange time between the row cutter and the opposite tool table, multiple tool table overlap and thread chip effective axis movement overlap function can be realized. The direct spindle indexing function during secondary machining shortens the actual idle time. Chip cutting tools have always played a very important role in the machining of the spindle and workpiece clamping parts, which provides a strong guarantee for constant machining accuracy. In terms of the market, the 38mm is its largest processing diameter, which makes the core machine have a great advantage in the precision shaft processing market. The series of machines can also be equipped with automatic feeding devices to achieve fully automated production of a single machine tool, reducing labor costs and defective products in the production process, and can be used to produce high-volume precision shaft parts.
