Background

Composite machining is one of the currently internationally most popular machining processes in the field of machining. Is an advanced manufacturing technology. The composite machining is realized by a plurality of different machining processes on one machine tool. Under the current large environment of domestic industry upgrading, salary improvement and shortage of technical workers, the demand of composite processing equipment for reducing the processing period and improving the processing precision is increasing. The composite processing is most widely applied and has the greatest difficulty, namely turning and milling composite processing. The turning and milling combined machining center is equivalent to the combination of a numerical control lathe and a machining center. At present, most of turning and milling composite processing is finished on a turning and milling composite processing center, a Y-axis guide rail which forms an included angle of 30 degrees with an X axis is additionally arranged on a carriage of a lathe in the X direction in the international traditional turning and milling composite processing center, when the lathe is in a chip cutting function, a main shaft drives a workpiece to rotate, the Y axis is fixed, the workpiece is cut in the circumferential direction through the movement of the X axis and the Z axis, when the workpiece needs to be eccentrically drilled in the end face or the circumferential direction, and when a groove or a plane is milled, the main shaft is additionally provided with a C axis function, and X, Y, Z axes are drilled or milled on the surface of the part through complex operation of a system.

The turning and milling combined machining has the following advantages:

(1) can realize one-time clamping to complete all or most of processing procedures, thereby greatly shortening the manufacturing process chain of products. Therefore, on one hand, the production auxiliary time caused by the card loading change is reduced, and meanwhile, the manufacturing period and waiting time of the tooling fixture are also reduced, and the production efficiency can be obviously improved.

(2) The clamping frequency is reduced, and the processing precision is improved. The reduction of the card loading times avoids the accumulation of errors caused by the conversion of the positioning reference. Meanwhile, most of the existing turning and milling composite processing equipment has an online detection function, and can realize in-place detection and precision control of key data in the manufacturing process, so that the processing precision of products is improved.
