What are the characteristics of the four basic motion modes of turning milling machine tool
Turning milling compound machine tools are the main types of compound machine tools. Generally, plane milling, drilling and tapping, slot milling and other milling processes are realized on the CNC lathe. It has the compound functions of turning, milling and boring. It can realize the processing concept of one-time clamping and full closing.
It uses the compound movement of milling cutter rotation and workpiece rotation to realize the cutting of workpiece, so as to ensure the shape accuracy, position accuracy and machining surface integrity of workpiece. Turning milling combined machining is not simply a combination of turning and milling on one machine tool, but a combination of turning and milling to complete various surface machining, which is produced under the conditions of greater development of NC technology today A new cutting theory and technology.
The movement of turning milling compound machining machine tool includes four basic movements: milling cutter rotation, workpiece rotation, milling cutter axial feed and radial feed. According to the relative position of the workpiece rotation axis and the tool rotation axis, the turning milling composite processing can be divided into axial turning milling processing, orthogonal turning milling processing and general turning milling processing. Among them, axial turning milling and orthogonal turning milling are the two most widely used turning milling machining methods. Because the axis of rotation of the milling cutter is parallel to the workpiece, it can not only process the cylindrical surface, but also the inner hole surface. Since the rotation axis of the milling cutter is perpendicular to the workpiece, the inner hole cannot be machined when the diameter of the inner hole is small. However, when machining the outer cylindrical surface, the longitudinal travel cutter for milling is not limited, and large longitudinal feed can be used. Therefore, Dongguan turning milling composite processing is more efficient when machining the outer cylindrical surface.
