1. Machine Tool Composition and Structure
The main body of a milling-turning machine tool consists primarily of core components such as the spindle drive, feed drive, bed, and worktable. It also includes auxiliary motion devices, hydraulic and pneumatic systems, lubrication systems, and cooling systems to meet the requirements of a CNC milling-turning machine tool and fully utilize the advantages of both turning and milling.
2. Combined Turning and Milling Motion
Milling-turning machining does not simply combine turning and milling into a single machine tool. Instead, it utilizes combined turning and milling motion to achieve machining of various surfaces. This combined motion includes four basic movements: cutter rotation, workpiece rotation, and axial and radial feeds. Depending on the relative position of the workpiece rotation axis and the tool rotation axis, milling-turning machining can be primarily categorized as axial turning and milling, orthogonal turning and milling, and general turning and milling.
In summary, the operating principle of a milling-turning machine tool is based on the coordinated action of spindle rotation, worktable motion, and a precision control system to achieve precise workpiece machining through combined turning and milling motion. This machine tool boasts high efficiency, high precision, and versatility, and has broad application prospects in aerospace, automotive, and mold manufacturing.
