What is the difference between a vertical machining center and a horizontal machining center?
The basic functions of the vertical machining center and the horizontal machining center are the same, and they are mainly milling. The two are very different, mainly reflected in structural differences and product positioning, processing range differences, etc., described in detail below.
The spindle structure of vertical machining center is different from that of horizontal machining center:
A vertical machining center refers to a machining center with a vertical spindle, and a horizontal machining center refers to a machining center with a horizontal spindle.
The vertical column and vertical column have different column structures:
The columns of vertical machining centers generally do not move, and are generally made as thick as possible in order to pursue rigidity. There is also a moving column vertical machining center. The table of the moving column vertical machining center only performs X or Y movement, and the column will perform Y or X movement accordingly. This design method has greater power requirements for the drive motor of the column. .
The column of the horizontal machining center must be a moving column. The vertical T-shaped horizontal machining center column moves in the X direction, and the inverted T-shaped horizontal machining center column moves in the Z direction. The structure of the mobile column requires that the column must be as light and compact as possible on the premise of satisfying rigidity. Foreign machine tools often use steel plate welded structures to solve this problem.
The table form of vertical machining center and horizontal machining center are different:
The vertical machining center table is generally a T-slot table with a cross slide structure. There are two sets of motion mechanisms responsible for the movement of the table in the vertical direction. The X-directional feed table is covered by the guide rail for the Y-directional feed. on.
The worktable of the horizontal machining center only performs X or Y movement. The worktable is generally a rotary worktable with dot matrix screw hole table, and it is relatively easy to choose the exchangeable double worktable.
The machining conditions of vertical machining center and horizontal machining center are different:
When the vertical machining center is processing the cavity or the concave surface, the chips are not easy to be discharged. In severe cases, it will damage the tool, damage the processed surface, and affect the smooth processing of the processing.
The horizontal machining center can easily remove chips during processing, and the processing conditions are relatively ideal.
The operation status of vertical machining center is different from that of horizontal machining center.
The vertical machining center is easy to clamp, easy to operate, easy to observe the processing situation, and easy to debug the program.
The workpieces processed by horizontal machining centers are generally large, difficult to set up, difficult to monitor the processing process, and relatively difficult to operate and debug.
The processing objects of vertical machining center and horizontal machining center are different:
The vertical machining center is limited by the height of the column and the tool changer. It cannot process parts that are too high. It is suitable for processing discs, sleeves, and plate parts. The workpiece volume processed is relatively small. If you want to realize the side processing of the workpiece, you must add an angle. Head or CNC turntable. If a rotary table that rotates along the horizontal axis is installed on the work table, it can be used to process spiral parts.
The horizontal machining center can complete the processing of the other four surfaces except the mounting surface and the top surface after one clamping, which is the most suitable for processing box parts, and the pentahedron processing can be realized after the angle head is installed.
The structure complexity of horizontal machining centers is higher than that of vertical machining centers. The number of factories capable of producing horizontal machining centers is much smaller than that of vertical machining centers. The price of horizontal machining centers with the same working range is often twice that of vertical machining centers. the above.
