Machining Center (MC) is referred to as MC, which is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system suitable for processing complex parts. The preparation of processing programs is an important factor in determining the processing quality. The machining center is a high-efficiency, high-precision CNC machine tool. The workpiece can be processed in multiple procedures in a single clamping. It also has a tool library and automatic tool change. The rich functions of the machining center determine the complexity of machining center programming.
The machining center can realize the linkage control of three or more axes to ensure that the tool can process complex surfaces. In addition to the linear interpolation and circular interpolation functions, the machining center also has various machining fixed cycles, automatic tool radius compensation, automatic tool length compensation, graphical display of the machining process, man-machine dialogue, automatic fault diagnosis, offline programming and other functions .
The machining center is developed from a CNC milling machine. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools with different uses on the tool magazine, the machining tools on the spindle can be changed by an automatic tool changer in one clamping to achieve a variety of machining Features.
The machining center can be divided into vertical, horizontal and composite machining centers in appearance. The main axis of the vertical machining center is perpendicular to the worktable, which 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 table surface of the worktable. Most of its worktables are CNC rotary tables controlled by servo motors. In the one-time clamping of the workpiece, the worktable can be processed by rotating the worktable. Box type workpiece processing. The compound machining center mainly refers to that there are two vertical and horizontal spindles on one machining center, or the spindle can change the angle by 90 °, so that the machining of five faces can be achieved in one clamping of the workpiece.
