The concept and classification of CNC machining center

The machining center was developed from a CNC milling machine. The biggest difference with the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing different tools on the tool magazine, the machining tool on the spindle can be changed in one clamping by the automatic tool changer to realize various machining. Features.

CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system for processing complex parts. CNC machining center is one of the most widely used and widely used CNC machine tools in the world. Its comprehensive processing ability is strong, the workpiece can complete more processing content after one clamping, and the processing precision is high. The batch workpiece with medium processing difficulty is 5~10 times more efficient than ordinary equipment, especially it can be completed. The processing that can not be completed by many ordinary equipments is more suitable for single-piece processing or small-to-medium batch multi-species production with complex shapes and high precision requirements. It combines the functions of milling, boring, drilling, tapping and cutting threads on one piece of equipment, giving it a variety of processes. Machining centers are classified according to the spatial position of the spindle machining: horizontal and vertical machining centers. Classified by process use: boring and milling machining center, composite machining center. Special classification by function: single workbench, double workbench and multi-workbench machining center. Machining centers for single-axis, dual-axis, three-axis and interchangeable headstocks.

The machining center is often divided into a vertical machining center and a horizontal machining center according to the state in which the main shaft is in space. The main axis of the machining center is called a vertical machining center when the space is in a vertical state, and the main axis is in a horizontal state. Machining center. The spindle can be converted vertically and horizontally, called the vertical horizontal machining center or the five-sided machining center, also known as the composite machining center. According to the number of processing center columns; there are single column and double column (gantry type).

According to the number of motion coordinates of the machining center and the number of coordinates controlled at the same time: there are three axes and two linkages, three axes and three linkages, four axes and three linkages, five axes and four linkages, and six axes and five linkages. The three-axis and four-axis refer to the number of motion coordinates of the machining center. The linkage refers to the number of coordinates that the control system can control the motion at the same time, thereby realizing the position and speed control of the tool relative to the workpiece.

According to the number and function of the workbench: there is a single workbench machining center, a double workbench machining center, and a multi-workbench machining center.

According to the processing accuracy: there are ordinary machining centers and high-precision machining centers. The general machining center has a resolution of 1μm, a maximum feed rate of 15~25m/min, and a positioning accuracy of about l0μm. The high-precision machining center has a resolution of 0.1μm, a maximum feed rate of 15~100m/min, and a positioning accuracy of about 2μm. Between 2~10μm, more than ±5μm, can be called precision grade.
