Horizontal machining center and vertical machining center
The horizontal machining center and the vertical machining center have the same thing, that is, they take the milling function as the main function. The differences between the two are: their structures are different, the product positioning is different, and the form of processing workpiece is also different.
1: The spindle structures of the two are different.
Horizontal machining center refers to the machining center with horizontal spindle; Vertical machining center refers to the machining center with vertical spindle.
2. The main component structure of the two; Column, with obvious difference.
The columns of horizontal machining centers are designed as movable columns. For positive T-shaped horizontal machining centers, their columns move in the X direction, while for inverted T-shaped horizontal machining centers, their columns move in the Z direction. The structure of mobile column requires that the column must be as light as possible on the premise of meeting the rigidity. Imported machine tools often use steel plate welding structure to achieve this goal.
The vertical column of the vertical machining center is generally designed to be immovable. In order to pursue rigidity, it is generally made as thick as possible. Occasionally, movable column type vertical machining centers are designed. The worktable of movable column type vertical machining centers only moves in the X or Y direction, while the column will move in the Y or X direction accordingly. This design method requires a large power for the driving motor of the column.
3. The workbenches of the two are different.
The worktable of the horizontal machining center is only designed to move in X or Y direction. The worktable is generally a rotary worktable with a lattice screw hole table, and it is relatively easy to choose and install an exchange type double worktable.
The worktable of vertical machining center is usually a T-groove worktable with cross slide structure. There are two sets of motion mechanisms responsible for moving in the mutually vertical direction. The worktable for X direction feeding is covered on the guide rail for Y direction feeding.
4. The chip removal conditions during processing are different.
Due to the structural characteristics of vertical machining centers, it is usually difficult to discharge the chips when machining the cavity or concave surface, and in serious cases, it will damage the tool, the machined surface, and affect the smooth processing.
The horizontal machining center is easy to remove chips when machining, and the machining condition is relatively ideal.
5. The controls are different.
Generally, the workpieces processed by horizontal machining centers are relatively large, difficult to install and clamp, difficult to monitor the processing process, and relatively difficult to operate and debug.
The vertical machining center is generally convenient for clamping, operation, observation and debugging.
6. The two processing objects are different.
The horizontal machining center can generally finish the machining of the other four surfaces except the mounting surface and the top surface after one clamping, which is suitable for machining box type parts. The pentahedron machining can be realized after the angle head is added.
However, the vertical machining center, limited by the height of the column and the tool changer, cannot process too high parts. It is suitable for processing disk, sleeve and plate parts. The volume of the workpiece processed is relatively small. If you want to achieve the side processing of the workpiece, you must install an angle head or a CNC turntable. If a rotary table rotating along the horizontal axis is installed on the workbench, it can be used to process spiral parts.
To sum up, the structural complexity of horizontal machining centers is more than that of vertical machining centers. The number of factories capable of producing horizontal machining centers is far less than that of vertical machining centers. The price of horizontal machining centers with the same scope of work is often more than twice that of vertical machining centers.

In fact, it is difficult to solve the problem of whether a three-axis CNC machining center is better or a four-axis machining center is better. There is only a problem that is not suitable for machining some kinds of parts. Basically, all three-axis machining centers can process the parts that can be processed by a four axis machining center, while the parts that can be processed by a four axis machining center may not be processed by a three-axis machining center.
