A vertical and horizontal double-spindle composite five-sided machining machine tool according to claim 1, characterized in that: The horizontal column (2) includes a first balancing cylinder (21) and a balancing cylinder bracket (22), and the first balancing cylinder (21) is arranged above the vertical column (3). The horizontal column (2) is movably connected to the horizontal spindle box (4) through the balancing cylinder bracket (22) and the balancing bracket (44).

3. A vertical-horizontal double-spindle compound five-face machining machine tool according to claim 1, characterized in that: Three second pressing blocks (56) for assisting in fixing the vertical spindle box (5) and the four sliders are provided on the side end surface of the vertical spindle box (5).

4. A vertical and horizontal double-spindle composite five-face machining machine tool according to claim 1, characterized in that: Four Y-axis linear guide rails are placed on the bed (1), and each of the Y-axis linear guide rails contains a slider. The slide (8) cooperates with the Y-axis linear guide rails through a plurality of sliders so that the slide (8) performs Y-direction horizontal motion on the bed (1). Two X-axis linear guide rails are placed on the slide (8), and the X-axis linear guide rails are provided with a plurality of sliders. The rotary table (9) cooperates with the X-axis linear guide rails through a plurality of sliders so that the rotary table (9) performs X-direction horizontal motion on the slide (8).

5. A vertical and horizontal double-spindle composite five-face machining machine tool according to claim 1, characterized in that: The Y-axis feed mechanism (10) uses a four-bearing structure at both ends of the lead screw and nut combination. The Y-axis feed mechanism (10) includes a lead screw (101), and the end of the lead screw (101) is connected to a motor (100) through a coupling. The motor (100) is movably connected to a motor base (102), and four bearings are arranged in the motor base (102). A first nylon bumper (105) for protecting the motor base (102) is placed at the front end of the motor base (102) to prevent the nut (104) from hitting the motor base (102) during movement, which may affect the transmission accuracy.
