1. Definition of vertical machining center and horizontal machining center:
Vertical Machining Center
The machining center refers to the axis of the spindle perpendicular to the workbench. It is mainly used to process complex parts such as plates, discs, molds and small shells. Vertical machining centers perform milling, boring, drilling, tapping and thread cutting. The vertical machining center is at least three-axis and two-linkage (generally three-axis and three-link linkage can be realized), and some can be controlled by five-axis and six-axis. For the vertical machining center produced by Fujian Yuding Machinery, customers generally require the addition of the first. Four axes to achieve the flipping of objects during processing. The height of the vertical machining center column is limited, and the processing range of the box type workpiece is reduced, which is a disadvantage of the vertical machining center. However, the vertical machining center has its inherent advantages: (1) workpiece clamping and positioning are convenient; (2) the cutting tool movement track is easy to observe, the debugging program is easy to check and measure, the problem can be found in time, the shutdown processing or modification is performed; Established, the cutting fluid can directly reach the tool and the machining surface; (3) The three coordinate axes are consistent with the Cartesian coordinate system, and the sense is intuitive and consistent with the pattern angle of view, and the chips are easy to be removed and dropped to avoid scratching the processed surface; 4) Compared with the corresponding horizontal machining center, the structure is simple, the floor space is small, and the price is relatively low.
Horizontal machining center
The spindle of the horizontal machining center is horizontal and usually has a square table for indexing rotary motion. Generally, there are 3 to 5 motion coordinates. Commonly, three linear motion coordinates plus one rotary motion coordinate can make the workpiece complete the processing of the other four surfaces except the mounting surface and the top surface after one clamping, which is most suitable. Processing box parts. Generally, it has an indexing table or a numerical control conversion table, which can process each side of the workpiece, and can also realize joint motion of multiple coordinates to process complex spatial surfaces. Some horizontal machining centers have automatic exchange workbench. When the workpieces on the workbench are processed, the workpieces on the workbench at the loading and unloading position can be loaded and unloaded, which greatly shortens the auxiliary time and improves the auxiliary time. Processing efficiency.
Second, the difference between vertical machining center and horizontal machining center :
1) Vertical machining center
The vertical machining center refers to the machining center with the spindle in the vertical state. The structure is mostly fixed column. The worktable is rectangular and has no indexing rotation function. It is suitable for processing discs, sleeves and plate parts. It generally has three linear motions. A coordinate axis and a rotary table that rotates along the horizontal axis can be mounted on the table to machine spiral parts.
The vertical machining center is easy to install, easy to operate, easy to observe and process, easy to debug, and widely used. However, due to the height of the column and the limitation of the tool changer, it is impossible to process parts that are too high. When machining the cavity or the concave profile, the chips are not easily discharged. In severe cases, the tool will be damaged, the processed surface will be damaged, and the processing will be affected smoothly. .
2) Horizontal machining center
Horizontal machining center refers to the machining center with the spindle in the horizontal state. Usually, it has a rotary table with automatic indexing. It usually has 3 to 5 motion coordinates. Commonly, three linear motion coordinates plus one rotary motion coordinate, workpiece After the card is loaded, the processing of the remaining four surfaces except the mounting surface and the top surface is completed, which is most suitable for adding the box-like parts. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during processing, which is advantageous for processing, but the structure is complicated and the price is relatively high.
