The machining center is a modern CNC machine tool used to process various complex parts and components, and is widely used in the fields of automobiles, aerospace, electronics, medical equipment, etc. It can perform multiple processing operations at the same time, such as milling, drilling, tapping, boring, cutting, etc. It has the characteristics of high precision, high efficiency, and high automation, and has become one of the important equipment in the modern manufacturing industry.
Principle
The working principle of the machining center is to clamp the workpiece on the workbench and cut the workpiece through the movement of the CNC system and the tool on three coordinate axes. The CNC system controls the movement and rotation of the tool to complete various complex processing procedures, such as milling, drilling, tapping, boring, cutting, etc. The CNC system of the machining center can quickly change the angle and position of the tool and the tool according to different processing requirements, thereby achieving fast, efficient and precise processing.
Composition structure
The machining center usually consists of the following parts:
(1) Machine tool body: The machine tool body is the core part of the machining center, consisting of a bed, columns, beams and other parts. The bed is the foundation of the machine tool body and is used to support components such as the workbench, spindle and tool magazine. The columns and beams are responsible for supporting and transmitting cutting force and inertia force, so that the machining center can stably perform high-speed processing.
(2) Workbench: The workbench is the part that clamps the workpiece, usually consisting of T-slots and fixtures. T-slots are used to install fixtures and workpieces. The fixtures can be freely adjusted according to the shape and size of the workpiece to ensure stable clamping and positioning of the workpiece.
(3) Tool system: The tool system is an important part of the machining center, including the spindle, tool magazine, automatic tool changer, etc. The spindle is the driving part of the cutting tool. Different cutting tools and cutting parameters can be selected according to different processing requirements. The tool magazine is the part that stores the cutting tools. It can automatically select and replace cutting tools according to processing requirements to improve production efficiency and processing accuracy.
(4) CNC system: The CNC system is the intelligent control part of the machining center, which is composed of computers, CNC devices, servo controllers, etc. The CNC system can control the movement and rotation of the tool through programming to achieve various complex processing procedures. In addition, the CNC system can also monitor the changes of various parameters during the processing process in real time to ensure processing quality and efficiency.
(5) Cooling device: The cooling device is usually composed of a coolant tank, a cooling pump, a nozzle, etc., which is used to cool the cutting tool and the workpiece, reduce the accumulation of friction heat and cutting heat, and can also flush chips and debris to ensure processing quality and tool life.
