15KW Servo Spindle Motor Power CNC Gantry Flange Drilling Machine 40mm Drilling Diameter

Application:

The CNC gantry drilling and milling machine is primarily engineered for executing drilling, chamfering, tapping, and milling operations on plate and structural components—such as flanges, discs, rings, and plates—with workpiece thicknesses falling within the effective processing scope. It facilitates the drilling of through holes and blind holes in both single-material parts and composite materials. The entire machining process is digitally governed, ensuring highly user-friendly operation. This equipment is competent in realizing automated production with high precision, adapting to multiple varieties, and supporting mass manufacturing.

Specifications:

1. Drilling Head:

The drilling power head employs a dedicated servo spindle motor, which transmits power to a specialized precision spindle via a toothed synchronous belt to enhance torque output. The spindle is fitted with a Japanese angular contact bearing configuration (four at the front and two at the rear, totaling six rows), enabling stepless speed variation. It is equipped with a pneumatic tool-changing system, ensuring rapid and convenient tool replacement.

Feed motion is driven by a servo motor in conjunction with a ball screw. The X and Y axes support linkage functionality and utilize semi-closed-loop control, enabling linear and circular interpolation operations. The spindle end features a BT50 taper hole, accompanied by a high-speed rotary joint, and is capable of processing with a high-speed U-drill through center outlet.

2. Transmission Device:

It adopts a high-precision design incorporating guide rails and sliders imported from Taiwan, ensuring smooth operation and effectively enhancing heavy-load capacity.

(1) The X-axis and Z-axis each utilize two rolling linear guides as the guiding and load-bearing tracks for lateral and longitudinal movement respectively, which can meet the technical requirements of high-speed drilling. The transmission of the X-axis and Z-axis employs AC servo motors to drive the precision ball screws for rotation, thereby realizing linear motion.

(2) The Y-axis is equipped with two heavy-duty rolling linear guides on each side, one of which features a side-hanging structure, collectively forming the Y-axis sliding track. This configuration meets the high rigidity and strength requirements of the gantry frame, while also embodying technical advantages such as a low friction coefficient, high movement speed, excellent vibration absorption performance, and an extended service life.

The X-axis transmission adopts dual servo motor synchronous drive technology: one servo motor is installed on each side, which synchronously drives the ball screws to rotate, thereby moving the gantry frame and enabling CNC machining operations.

The CNC gantry drilling and milling machine is a high-performance industrial device specifically developed for the precision machining of plate and structural components. Its main applications cover an extensive range of operations, including drilling, chamfering, tapping, and milling, focusing on workpieces such as flanges, discs, rings, and plates, with their thickness strictly within the machine’s specified effective processing range.

The High Speed CNC Plate Drilling and Milling Machine plays a pivotal role in sectors such as steel structure workshops, wind power generation, and bridge construction.

Within steel structure workshops, it facilitates precise drilling and milling of structural plates and connecting components, ensuring the robust assembly of frameworks. In the wind power domain, it processes turbine towers and flange parts with high precision, enabling them to withstand harsh environmental conditions. For bridge construction, it handles the machining of girders and brackets, ensuring stable and durable connections under dynamic loads. Its operational efficiency provides strong support to these critical infrastructure and clean energy fields.
