A major advantage of a vertical machining center is that it has an automatic tool changing device
Vertical machining center is a CNC machine tool with a tool library and an automatic tool changing device, which can automatically and continuously complete multiple processes such as milling, drilling, boring, reaming, threading, groove, etc. after clamping the workpiece. Compared with other machine tools, the machining center greatly shortens the time for workpiece clamping, measurement, and machine tool adjustment. Shorten the turnover, handling, and storage time of workpieces, making the cutting time utilization rate of machine tools 3-4 times higher than that of ordinary machine tools; It has good processing consistency and can eliminate human interference factors in the process, thereby improving processing accuracy and efficiency, and shortening production cycle [1]; In addition, the machining center has an automatic tool changing device, which solves tool problems and has highly automated multi process management functions. The vertical machining center is mainly composed of basic components, spindle components, feed mechanism, CNC system, automatic tool change system, and auxiliary devices.
The spindle component is composed of components such as the spindle box, spindle motor, spindle, and bearings. The starting, accurate stopping, and variable speed actions of the spindle are controlled by the CNC system, and participate in laser cutting china motion through the tools installed on the spindle. The CNC system is composed of a CNC device, PLC, servo drive device, and operation panel, which is the control center for completing the machining process.
The automatic tool change device is composed of components such as a tool magazine and a robotic arm. When a tool change is required, the CNC system sends instructions, and the robotic arm or other clamping device takes the tool out of the tool magazine and loads it into the spindle hole. This machining center’s tool magazine is a bamboo hat type, equipped with 12 knives. When in use, when the tool change command of “M06T * *” is input, the tool magazine keeps rotating and cannot be stopped in the selected tool state, resulting in the inability to change the tool. One of the great advantages of a machining center is its automatic tool changing device, which makes the machining more flexible. If the tool changing process of the machining center malfunctions, although manual tool changing is possible, it greatly reduces the machining efficiency and loses the true meaning of the machining center.
To maximize the high efficiency of CNC machine tools, it is necessary to ensure their operating rate, which requires stability and reliability of the machine tool. When a machine tool malfunctions, the cause of the malfunction should be diagnosed as soon as possible and a reasonable solution should be proposed for repair. If used as a metaphor, it means paying attention to maintenance and avoiding illness in daily life; After falling ill, seek medical attention in a timely manner, diagnose the cause, prescribe appropriate medication, and recover as soon as possible.
Modern equipment requires modern and scientific management. The comprehensiveness and complexity of CNC machine tools determine that there are their own methods and characteristics for troubleshooting and problem-solving. Mastering these methods can ensure the stable and reliable operation of CNC machine tools.
