To put it simply, cnc vertical machining center, like other CNC milling processing equipment, has the ability to efficiently process complex curved workpieces and special-shaped contour workpieces. It also has the advanced function of automatically changing processing tools. With the help of this processing feature, the machine tool can realize automatic transfer processing of various types of workpieces, especially multi-process complex workpieces. The workpiece can be integrated and automatically completed on a single processing equipment to complete various processing projects such as drilling, milling, boring, reaming, and tapping.
The cnc vertical machining center has the above-mentioned high automatic processing ability. In addition to the control device of the machine tool and the processing program of the workpiece, the hardware is mainly configured with two parts: a tool magazine and an automatic tool changer. With the tool magazine, the processing tools of each process of the workpiece can be better stored and managed, and the automatic tool change mechanism enables the machine tool to promptly replace the corresponding processing tools of the cutting process when each process is completed. They are independent of each other. And an indivisible whole. The tool change mechanism is different according to the tool magazine configuration of the machine tool.
According to the different processing forms and processing requirements of cnc vertical machining center, the common tool magazines mainly include hat type tool magazines, disc manipulator tool magazines, chain tool magazines, etc. The corresponding tool changing methods can be divided into direct tool changing methods, manipulator tool changing methods and turret head methods.
The so-called manipulator tool change method means that the manipulator grasps the tool, selects the tool and changes the tool when changing the tool.
The so-called direct tool change method means that the tool change process is completed by the cooperation of the tool magazine and the headstock, which is a direct tool change method.
The turret head mode is a tool change mode in which the required tool is moved to the corresponding position through the rotation of the brick tower. It is generally a sequential tool change with the advantages of compact structure and short tool change time. It is generally used for machining crankshafts and other slender workpieces and needs to complete multiple processes in complex process processing occasions.
