BT50-150 Spindle Taper CNC Gantry Drilling And Milling Machine 50mm Max Drilling Diameter

Application:

This equipment is engineered for the drilling, chamfering, tapping and milling of plate-type components and structural parts. It is primarily utilized for the high-efficiency drilling of workpieces including flanges, discs, rings and plates, on the condition that their thickness lies within the effective processing scope. The device facilitates the drilling of through holes and blind holes in both single-material components and composite materials. The machining process of this machine tool is governed by digital technology, which ensures a high level of operational convenience. It supports the achievement of automated production, high-precision machining, multi-variety manufacturing and mass production requirements.

Machine Structure

This machine is primarily constituted by core components including a bed workbench, a movable gantry, a movable sliding saddle, a drilling and milling power head, an automatic lubrication unit, a protective mechanism, a circulating cooling system, a numerical control system, and an electrical system, among others. It employs a rolling guide pair for support and guidance purposes, and is driven by a precision lead screw pair. Consequently, this machine tool exhibits high positioning accuracy and superior repeat positioning accuracy.

Product Features

1. Drilling Power Head

The drilling power head is equipped with a dedicated servo spindle motor, which adopts a toothed synchronous belt for speed reduction and torque enhancement to drive a specialized precision spindle. The spindle utilizes six rows of angular contact bearings (four at the front and two at the rear, of Japanese origin) to achieve stepless speed regulation. A pneumatic tool changing system is integrated into the spindle, enabling more precise, rapid, and convenient tool replacement. The feed movement is driven by servo motors in conjunction with ball screws. The X-axis and Y-axis support linkage functionality and employ semi-closed-loop control, facilitating the realization of linear and circular interpolation capabilities. The spindle end is designed with a BT50 taper hole and fitted with a high-speed rotary joint, allowing for processing operations using a high-speed U-drilling center.

2. Transmission Device

The high-precision design of guide rails and sliders sourced from Taiwan guarantees smooth operational performance and effectively enhances heavy-load bearing capacity.

3. Automatic Lubrication Device and Protective Device

This machine tool is outfitted with an original volumetric partial-pressure automatic lubrication device sourced from Taiwan. This device enables automatic lubrication of all kinematic pairs—including guide rails, lead screws, and racks—without any coverage gaps, thereby safeguarding the service life of the machine tool. The X-axis and Y-axis of the machine tool are fitted with dust-proof protective covers, while waterproof splash guards are installed around the workbench.

The CNC gantry drilling and milling machine is a high-performance industrial equipment specially designed for the precision machining of plate-type components and structural parts. Its core application scope covers a comprehensive range of machining operations, including drilling, chamfering, tapping, and milling. This equipment is customized for processing workpieces such as flanges, discs, rings, and plates—with the key requirement that the thickness of these workpieces strictly meets the machine’s specified effective machining range.

The High Speed CNC Plate Drilling and Milling Machine serves as a core piece of equipment in steel structure workshops, wind power projects, and bridge construction sectors. Within steel structure workshops, it enables precise drilling and milling operations on structural plates and connectors, laying a solid foundation for the robust assembly of steel frames. For wind power applications, it processes wind turbine towers and flanges with high precision—a critical requirement to ensure these components can withstand harsh operating conditions (e.g., strong winds, temperature fluctuations). In bridge construction, it undertakes the machining of girders and brackets, guaranteeing stable and durable connections that can endure dynamic loads throughout the bridge’s long-term service life. Its outstanding operational efficiency provides reliable support to these key fields, which act as the backbone of infrastructure development and clean energy advancement.
