Horizontal machining center
Refers to a machining center where the spindle axis is parallel to the worktable, and is mainly suitable for machining box parts.
The main axis of the horizontal machining center is in a horizontal state, usually with a square worktable that can perform indexing rotary motion. Generally, there are 3 to 5 motion coordinates. The common is three linear motion coordinates plus one rotary motion coordinate. It can make the workpiece complete the processing of the other four surfaces except the installation 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 all sides of the workpiece; it can also be used for joint movement of multiple coordinates in order to process complex spatial curved surfaces.
Some horizontal machining centers are equipped with automatic exchange worktables. While processing the workpieces on the worktable at the working position, they can also load and unload the workpieces on the worktable at the loading and unloading position, thereby greatly shortening the auxiliary time and improving Processing efficiency.
Compared with the vertical machining center, the horizontal machining center has a complicated structure, a large area, and a relatively high price. Moreover, the horizontal machining center is inconvenient to observe during processing, and it is inconvenient to clamp and measure parts, but the chip is discharged during processing Easy and beneficial to processing.
Vertical Machining Center
Refers to the machining center where the axis of the spindle is perpendicular to the worktable, and is mainly suitable for processing complex parts such as plates, discs, molds and small shells. The vertical machining center can complete the processes of milling, boring, drilling, tapping and thread cutting. The vertical machining center is at least three-axis two-linkage, generally can achieve three-axis three-linkage. Some can perform five-axis and six-axis control. The vertical column height of the vertical machining center is limited, and the processing range of the box-type workpieces should be reduced. This is a disadvantage of the vertical machining center. However, it is easy to clamp and position the workpiece in the vertical machining center; the trajectory of the cutting tool is easy to observe, the debugging program is easy to check and measure, the problem can be found in time, and processing or modification can be stopped; the cooling condition is easy to establish, and the cutting fluid can directly reach the tool and the machining surface; The three coordinate axes coincide with the Cartesian coordinate system. It feels intuitive and consistent with the view angle of the pattern. Chips can be easily removed and dropped to avoid scratching the processed surface. Compared with the corresponding horizontal machining center, the structure is simple, the area is small, and the price is low.
