CNC Double-Spindle Gantry Mobile High-Speed Drilling Milling Machine

  1. The function of the equipmentThe machine tool is a gantry mobile CNCdual-axis high-speeddrilling machine, which is mainly used for efficient processing such as through holes, blind holes, step holes, chamfering, lightmilling and other parts of tube sheets, flanges, rings and other parts. Carbide drill bits can be used for internal cooling and high-speed drilling, which is widely usedin steel structure, bridge, pressure vessel, chemical environmental protection, engineering machinery, ships and other industries. The processing process is numerically controlled, easy to operate, and can realize automated, high-precision, multi-variety, mass production.2.

The structure of the machine toolThe equipment mainly includes bed and longitudinal skateboard, workbench, gantry and transverse skateboard, vertical ramdrilling powerbox, automaticchip conveyor, pneumatic system, circulating cooling system, centralized lubrication system and protective device, electrical system, CNC systemand other components. 1. The bed adopts steel plate welding structure, which is treated by overall annealing and stress relief, and the accuracy is stable. This equipmentadopts bed fixation, the bed is distributed on the left and right sides of the workbench, the longitudinal (X-axis) of the gantry moves against the horizontal arrangement of the bed with an inlet high bearing capacity linearrolling guide pair and precision ball screw pair, and the drive is driven by servo motor. When the ball screw is installed, the lead screw is pre-stretched, eliminating the gap, and the transmission accuracy is high. The double-sided synchronous drive ensures the parallel movement of the gantry, ensures the perpendicularity of the Y axis to the X axis at any position, and distributes multiple adjustable bolts on the bottom surface of the bed, which can easily adjust the level of the bed table.2.The worktable adopts a fixed form, which is a steel plate welded structure, all of which are heat treated to remove stress, with large bearing capacity and 2~3 times that of ordinary CNC gantry drilling and milling machines. There are several T-grooves on the work surface, witha width of 28 mm, which can be used to install special fixtures ordirectly clamp workpieces. A high load-bearing capacity anchor is used on the foot of the workbench, which can easily adjust the level of the bed and workbench.3.The gantry is a welded steel structure, which is treated with stress relief annealingtreatment and has stable precision. Two linear rolling guide pairs with ultra-high bearing capacity are installed on the front side of the gantry. And two sets of precision ball screw pairs and servo motors are installed on the top to make the two power head slide plates move in the Y axis direction. The ball screw adopts double nut preload, and the lead screw is pre-stretchedduring installation, eliminating the gap, and the transmission accuracy is high. The two power boxes can work simultaneously or independently. The movement of the gantry is realized by the servo motor through
