Difference Between Vertical Machining Center And Horizontal Machining Center

Vertical machining center is a highly automatic multi-function CNC machine tool with tool magazine and automatic tool change device.It is mainly applicable to the processing of complex parts such as moulds, small shells and plates. At the same time, it can also complete milling, drilling, tapping and thread cutting processes. The disadvantage of vertical machining center is that its column height is limited, so the machining range of box type workpiece should be reduced. However, it has many advantages, such as: ① It is easy to observe the motion track of the cutting tool, so that problems can be found in time for modification. ② The three coordinate axes are consistent with the Cartesian coordinate system. The pattern and visual angle are the same, which can easily eliminate chips and avoid scratching the machined surface. ③ The cooling conditions are easy to establish, and the cutting fluid can directly reach the tool and the machined surface. Compared with the corresponding horizontal machining center, the price is lower, the structure is simple, and the floor area is smaller.

Horizontal machining center refers to the machining center which spindle axis is set parallel to the workbench, which is mainly applicable to machining box type parts. It generally has 3-5 motion coordinates, which can enable the workpiece to complete the processing of the other four surfaces except the mounting surface and top surface after one clamping, and is most suitable for processing box type parts. Each side of the workpiece can be processed by indexing table or NC conversion table; It can also perform joint movement of multiple coordinates to process complex spatial surfaces. Compared with the vertical machining center, the horizontal machining center is more expensive, occupies a larger area, and is inconvenient to observe during processing. It is also inconvenient to measure and clamp parts.
