Working principle of vertical machining center

Vertical machining center refers to a machining center with the spindle axis vertically arranged to the workbench, with a tool magazine and automatic tool change device. It can automatically complete various processes after the workpiece is clamped in one time: the workpiece is placed on the machine tool workbench and clamped by clamping, and relying on the machine tool positioning system such as optical tool setters, probes, etc. to ensure the accurate position in the machine tool coordinate system. It is mainly suitable for processing complex parts such as plates, discs, molds and small shells. Able to complete milling, boring, drilling, tapping and cutting threads. CNC system setting parameters: including machine tool coordinate system settings, cutting condition settings, spindle speed settings, etc., and are adjusted according to workpiece material, shape, size and processing requirements.

1. Writing and loading programs: Use CAM software to write processing programs according to workpiece drawings and processing technology requirements, load the program into the CNC system through communication interfaces or USB flash drives, control the movement and cutting actions of each axis of the machine tool, and realize automatic processing.
2. Tool selection and replacement: According to processing requirements, the tool is taken out from the tool magazine through the automatic tool changing device of the machine tool and installed on the spindle to achieve rapid tool change.
3. Cutting operation and monitoring: The CNC system controls parameters such as spindle speed, feed speed and cutting depth for stable cutting. At the same time, the monitoring system detects cutting force, temperature, vibration and other parameters in real time, and promptly alerts and measures are taken when abnormalities are abnormal.
4. Processing accuracy and quality assurance: High-precision transmission mechanism, guide rails and lead screws are used to ensure the positioning accuracy and repeat positioning accuracy of each shaft, use advanced measurement and compensation technology to measure and compensate errors in real time, and strictly control factors such as cutting conditions, tool wear and workpiece deformation.
5. Cooling and chip removal treatment: Use cutting fluid to cool the cutting area to reduce tool wear and thermal deformation of the workpiece. At the same time, use chip removal devices such as chip removal devices, chip removal belts, etc. to promptly discharge chips to keep the processing area clean.
