CNC gantry drilling machine is a horizontal CNC drilling machine with gantry frame and three spindles. Can process three parts at the same time, high production efficiency. The equipment can be used to produce steel, stainless steel, titanium, nickel, zirconium, tantalum, Monel, Hazelloy and other simple materials, as well as titanium/steel, nickel/steel, zirconium/steel, tantalum/steel and other composite materials production, drilling, reaming, reaming, drilling blind holes, internal hole cutting (using special auxiliary tools) and other functions, drilling with ordinary twist drill.

CNC gantry drilling machine is mainly composed of bed, moving gantry, longitudinal sliding table, drilling power box, CNC sliding table, automatic chip removal and circulating cooling device, electrical system and so on.

1, bed table:

The bed is composed of 900 width, 5410 length and 800 height, and the left, middle and right sections of the main bed are connected with the bridge section. The total width is 4560, welded steel structure, after manual aging treatment. CNC gantry drilling machine work table installed 16 trays, the top of the T-slot, slot width 28, easy to clamp the workpiece. On the left and right sides of the bed, two linear rolling guides and precision ball screws are arranged on each side, with a spacing of 450 and a length of 6410, for the movement of the longitudinal sliders of the gantry. CNC gantry drilling machine body bottom surface is distributed with adjustable bolts, can easily adjust the height of the body table.

2, moving gantry:

The gantry frame of CNC gantry drilling machine is 5550 wide and 1726 high, which is assembled by steel plate. There are two large-capacity linear rolling guides with a distance of 650 and a length of 4550 on the front side of the gantry. Two sets of precision ball screws and AC servo motors are mounted on the top to move the three power heads in the Y direction. A drilling power box is installed above each power head slide, and a drill bit can be installed on the main shaft. CNC gantry drilling machine both ends of the power head skateboard on both sides of the flexible guide rail.

3. Longitudinal guide rails

The longitudinal slide board is a welded steel structure with right-angle curved plates distributed left and right. The vertical surface of the left and right longitudinal sliding table of the CNC gantry drilling machine is equipped with two belt wheels with 2kW AC servo motors and a transmission ratio of 2. The small pulley is installed on the spindle motor, the large pulley is connected with the ball nut, and the servo motor is driven by the pulley. The ball nut rotates on the ball screw to drive the slider to move on the rolling guide rail. When loading and unloading work pieces, the two power heads can be moved to both ends of the CNC gantry drilling machine to facilitate loading and unloading work pieces.
