[0002] A machining center is a high-efficiency, precision CNC machine tool capable of machining complex curved surfaces and precision parts. It boasts advantages such as high precision, high speed, high flexibility, and high automation. Based on the number of axes, it can be divided into three-axis, four-axis, five-axis, and multi-axis machining centers (six axes or more). Based on different worktables, it can be divided into vertical and horizontal types. Based on different control systems, it can be divided into servo control systems and machining centers using digital control technology. The working process mainly includes the following steps: placing the workpiece on the machine tool's worktable and clamping it using a fixture or pneumatic device; before machining, inputting the workpiece coordinates and machining path into the CNC system; using a cutting tool to cut the workpiece surface; the cutting tool being automatically controlled by the CNC system to machine along a pre-set path; when multiple parts need to be machined, reinstalling the cutting tool; and continuously monitoring the workpiece accuracy during machining, making corresponding adjustments based on the monitoring results.

[0003] Existing tool changers for three-axis machining centers facilitate tool replacement. For example, there is a tool changer for a three-axis machining center with publication number CN221539009U and another with publication number CN216326816U.
