The machining center is an efficient and high-precision CNC machine tool. The workpiece can be processed in multiple processes in one clamping. It is also equipped with a tool library and has an automatic tool change function. These rich functions of the machining center determine the complexity of machining center programming.
The machining center can realize linkage control of three axes or more to ensure that the tool can process complex surfaces. In addition to linear interpolation and arc interpolation functions, the machining center also has various processing fixed cycles, automatic tool radius compensation, automatic tool length compensation, graphical display of the processing process, human-machine dialogue, automatic fault diagnosis, offline programming and other functions .
Machining centers are developed from CNC milling machines. The biggest difference from CNC milling machines is that the machining center has the ability to automatically exchange processing tools. By installing tools for different purposes on the tool magazine, the processing tools on the spindle can be changed through the automatic tool changer in one clamping to achieve a variety of processing. Function.
Machining centers can be divided into vertical, horizontal and composite machining centers in appearance. The spindle of the vertical machining center is perpendicular to the workbench. It is mainly suitable for processing plate and shell workpieces, and can also be used for mold processing.
The spindle axis of the horizontal machining center is parallel to the workbench surface. Most of its workbench is a CNC rotary table controlled by a servo motor. In one clamping of the workpiece, multiple processing surfaces can be processed through the rotation of the workbench, which is suitable for Processing of box workpieces. The compound machining center mainly refers to a machining center that has two vertical and horizontal spindles or the spindle can change the angle by 90°, so that five surfaces of the workpiece can be processed in one clamping.
