Machining center: It is a highly automated multifunctional CNC machine tool with tool magazine and automatic tool changer.
After the workpiece is clamped once on the machining center, the digital control system can control the machine tool to automatically select and replace the tools according to different procedures, and automatically change the spindle speed, feed, and the motion path of the tool relative to the workpiece and other auxiliary functions. Multi-process processing on several surfaces of the workpiece. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.
Vertical machining center refers to a machining center where the axis of the main shaft is perpendicular to the worktable. It is mainly suitable for processing complex parts such as plates, plates, molds and small shells. The vertical machining center can complete processes such as milling, boring, drilling, tapping and thread cutting. The vertical machining center is at least three-axis and two-linkage, and generally can achieve three-axis and three-linkage. Some can carry out five-axis or six-axis control. The height of the column of the vertical machining center is limited, and the processing range of box-like workpieces must be reduced. This is the shortcoming of the vertical machining center. But the vertical machining center is easy to clamp and locate the workpiece; the cutting tool movement track is easy to observe, the debugging program is convenient to check and measure, and the problem can be found in time, and the shutdown process or modification can be performed; the cooling condition is easy to establish, and the cutting fluid can directly reach the tool and the processing surface; The three coordinate axes are consistent with the Cartesian coordinate system, and the intuitive feel is consistent with the viewing angle of the drawing. The chips are easy to remove and fall to avoid scratching the processed surface. Compared with the corresponding horizontal machining center, the structure is simple, the floor space is smaller, and the price is lower.
According to the guide rail classification
According to the form of the guide rail of each axis of the vertical machining center, it can be divided into hard rail and linear rail. The hard rail is suitable for heavy cutting, and the linear rail movement is more sensitive.
Classification by speed
The spindle speed of vertical machining center is 6000-15000rpm for low speed type, and above 18000rpm is for high speed type.
Classification by structure
According to the bed structure of the vertical machining center, it can be divided into C type and gantry type.
