Product Characteristics
The G-V1220A double column machining center is a large and medium-sized machine tool. The workpiece can automatically and continuously complete milling, drilling, boring, expanding, reaming, countersinking, tapping and other processes after one clamping. The machine tool is suitable for large Processing of various types of small and medium-sized batches of complex parts such as medium-sized boxes, plates, disks, valves, and shells.
The whole machine structure is a double column structure, with integrated columns and beams designed to improve the overall rigidity of the columns. The basic large parts are made of high-quality resin sand molding and high-strength cast iron materials to ensure high rigidity and stable accuracy of the machine tool. The main castings have undergone finite element analysis, and the ribs are reasonably arranged to fully meet the needs of high-torque cutting of machine tools.
The spindle adopts a high-speed spindle unit with a standard belt-driven BT50-6000rpm spindle, which has high cutting efficiency.
The front end of the spindle adopts a labyrinth design, and the spindle has an air curtain protection function to prevent cutting fluid from entering the spindle bearing.
The spindle has a central air blowing function and is equipped with an automatic circulating water coolant cooling device to reduce the temperature rise and thermal deformation of the spindle and maintain high machining accuracy.
The main spindle box movement (Z-axis) is equipped with a nitrogen balance device. Even when moving at high speed, the counterweight will not shake; the precise ratio of the counterweight to the main spindle box weight can obtain the best processing characteristics, and the Z-axis drive motor has Good load characteristics.
The three-axis feed adopts a direct connection drive method between the motor and the high-precision ball screw. The large-diameter ball screw is pre-stretched and installed to further improve the transmission rigidity and positioning accuracy.
The X/Y/Z -axis guideways adopt roller guideways respectively, which have high rigidity, low friction, low noise, strong shock resistance, and can carry greater cutting forces.
The guidewayss and ball screws of the machine tool adopt a timed and quantitative lubrication system, which can adjust the oil supply cycle and amount of each lubrication point, and realize fully automatic centralized lubrication through electrical system control.
The chip removal of the machine tool adopts double screw conveyor, which is automatic, user-friendly and high-efficiency. It is also equipped with a front chain plate chip conveyor, which greatly reduces manual cleaning time.
The machine tool water tank adopts a multi-layer filtration system structure to provide good cutting fluid for workpiece processing.
