A vertical machining center should have at least three axes and two linkage, and can generally achieve three axes and three linkage. Some can be controlled with five or six axes. The height of the vertical machining center column is limited, and the machining range for box type workpieces needs to be reduced, which is the disadvantage of vertical machining centers. But the vertical machining center is convenient for workpiece clamping and positioning; The movement trajectory of the cutting tool is easy to observe, the debugging program is convenient for inspection and measurement, and problems can be detected in a timely manner for shutdown or modification; Cooling conditions are easy to establish, and cutting fluid can directly reach the tool and machining surface; The three coordinate axes are in line with the Cartesian coordinate system, which feels intuitive and consistent with the perspective of the pattern. Chip removal and falling are easy to avoid scratching the processed surface. Compared with the corresponding horizontal machining center, it has a simple structure, less land occupation, and lower price.
Vertical machining center
Simply put, both vertical machining centers and engraving and milling machines are essentially CNC machining equipment of the milling type. They are completely different in terms of processing capabilities and usage scenarios. The vertical machining center is equipped with a tool library and an automatic tool changing device, which not only has milling processing capabilities, but also can perform various composite processing capabilities such as drilling, boring, reaming, and tapping. Besides milling, engraving and milling machines can only perform engraving processing, not as powerful as the former. Specifically, we can take a look at their respective processing characteristics:
1. Characteristics of vertical machining centers
Simply put, a vertical machining center is a highly automated multifunctional CNC machine tool with a tool library and automatic tool changing device. It is developed on the basis of CNC boring and milling machines. Mainly suitable for processing complex workpieces such as plates, discs, molds, and shells. The biggest processing feature is the ability to centrally process various processes such as drilling, milling, boring, reaming, tapping, etc. of the workpiece through a tool library and automatic tool changing device, while the workpiece is clamped at once.
2. Characteristics of engraving and milling machines
Simply put, engraving and milling machines were developed on the basis of engraving machines. In order to achieve the ability of milling processing, the main shaft diameter of the engraving machine has been enlarged, the power of the servo motor has been increased, and the bearing capacity of the bed has been increased, while maintaining the high speed of the main shaft, making it capable of engraving and milling processing.
