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:
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.
