What structure does the machining center consist of?
CNC machining center is mainly composed of CNC device, servo system, machine tool body and tool magazine. It integrates the functions of CNC milling machine, CNC boring machine and CNC drilling machine with powerful functions.
1. Basic components: The basic components refer to the bed castings. It consists of a bed, a bracket and a worktable; it is the basic component of a CNC machining center, most of which are cast iron, because the machining center needs to withstand static loads and cutting dynamic loads during operation. Therefore, the rigidity of the bed casting is relatively high, and it is also the most important part of the CNC machining center.
2. Spindle components: It consists of spindle motor, spindle box, spindle and spindle bracket and other components;
3. Control system: CNC machining center CNC system consists of CNC device, programmable controller, servo drive device, and motor;
4. Servo system: The function of the servo system is to convert the signal sent by the numerical control device into the motion of the moving parts of the machine tool, and its performance is one of the main factors that determine the machining accuracy and surface quality. The production efficiency of the machine tool;
5. Automatic tool changing device: it is composed of tool magazine, manipulator and driving mechanism;
6. Automatic pallet replacement system: In order to further shorten the non-cutting time, some CNC machining centers are equipped with two automatic workpiece exchange pallets, one is installed on the worktable for processing, and the other is located outside the worktable for workpiece loading and unloading, which can reduce auxiliary time, improve processing efficiency;
7. Auxiliary system: including lubrication device, cooling device, chip removal device, protection device, hydraulic pressure and random detection system. It plays a decisive role in ensuring the working efficiency, working accuracy and reliability of the machining center.
