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

According to the number of movement coordinates of the machining center and the number of simultaneously controlled coordinates: there are three-axis two-linkage, three-axis three-linkage, four-axis three-linkage, five-axis four-linkage, six-axis five-linkage, etc. The three-axis and four-axis refer to the number of motion coordinates possessed by the machining center, and the linkage refers to the coordinate number that the control system can control the motion at the same time, so as to realize the position and speed control of the tool relative to the workpiece.

CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system, which is suitable for processing complex parts. CNC machining center is currently one of the world's highest output and most widely used CNC machine tools. Its comprehensive processing ability is strong, and the workpiece can complete more processing content after one clamping, and the processing accuracy is higher. For batch workpieces with medium processing difficulty, the efficiency is 5 to 10 times that of ordinary equipment, especially it can be completed The processing that cannot be completed by many common equipments is more suitable for the processing of single parts with complex shapes and high precision requirements, or the production of multiple varieties in small and medium batches.

The CNC machining center is a CNC machining machine with more complete functions. It concentrates the functions of milling, boring, drilling, tapping and thread cutting on a single device, so that it has a variety of technological means. The machining center is provided with a tool magazine, which stores different numbers of various tools or inspection tools, which are automatically selected and replaced by the program during the machining process. This is the main difference between it and CNC milling machine and CNC boring machine. Especially for work pieces that must use tooling and special machine equipment to ensure product quality and efficiency. This will save a lot of time and cost for the development and modification of new products, so that the company has a strong competitiveness.
