Combined with the servo turret, all processing steps of the workpiece can be completed in a single setup, resulting in higher precision and efficiency throughout the entire processing. The baffle along the edge of the base, with its downward-facing inclined plate forming a chip discharge port, facilitates chip collection. The moving base is designed in an I-shape, with the sliding plate directly fitted onto it.

[0027] 2. The tool magazine, fifth motor, tilting frame, tool holder, first electric telescopic component, electric rotating shaft, second electric telescopic component, and spare tool slot enable the tool magazine to facilitate quick tool changing with the boring and milling head, and allow some tools that need to be replaced and cleaned to be removed and stored for easy access by personnel later.
