Heat Exchangers Used Cnc Plate Drilling Machine 20/30KW Servo Spindle Motor Power
Application:
The CNC Gantry Plate Drilling and Milling Machine is purpose-built for high-precision machining of tube sheets, flanges, bearing plates, heat exchangers, and other plate-type workpieces widely used in petrochemical processing, nuclear energy, wind power, boiler manufacturing, and steel structure fabrication. The machine supports high-speed drilling with internally cooled carbide tools as well as externally cooled twist drills. By integrating drilling, chamfering, tapping, milling, and boring into a single machining platform, it delivers exceptional versatility and productivity. An optional automatic right-angle milling head further extends its capabilities, allowing efficient side drilling, tapping, and milling operations on complex workpieces.

Product features
1. The equipment is mainly composed of a heavy-duty machine bed, longitudinal slide system, gantry framework, cross slide, vertical feed unit, drilling and milling spindle head, worktable, coolant circulation system, automatic chip removal system, centralized lubrication system, pneumatic unit, electrical control system, and other auxiliary assemblies, forming a comprehensive and highly efficient machining platform.
2. The servo-driven sliding spindle head is capable of performing drilling, reaming, tapping, chamfering, and groove milling operations. It can operate independently or synchronously with multiple CNC axes to provide maximum machining flexibility. The spindle utilizes a high-precision Taiwan-manufactured BT50 spindle with an internal coolant supply and a butterfly spring automatic tool-clamping mechanism. Hydraulic tool unclamping enables fast, convenient replacement of drills and milling cutters, significantly improving production efficiency.
3. High-precision linear guideways are incorporated throughout the machine to ensure smooth travel, outstanding rigidity, and excellent motion accuracy. The feed system is powered by an AC servo motor through a synchronous belt and precision ball screw transmission, providing superior positioning accuracy, repeatability, and long-term machining stability.
4. Both the machine base and gantry structure are manufactured from premium cast iron or high-strength welded steel plate. All structural components undergo high-temperature stress-relief annealing before machining, followed by secondary stress-relief treatment after semi-finishing. Final precision machining guarantees exceptional structural rigidity, long-term dimensional stability, and consistently reliable machining accuracy throughout the machine's service life.
The CNC Gantry Plate Drilling and Milling Machine is a high-performance machining solution specifically developed for precision processing of plate-type components and structural parts. It is ideally suited for machining flanges, discs, rings, flat plates, and similar workpieces within the machine's specified thickness capacity. Its robust structural design, advanced CNC control, and multifunctional machining capabilities make it an ideal choice for demanding industrial manufacturing environments requiring both precision and productivity.
Within steel structure fabrication plants, the machine performs high-precision drilling and milling of structural plates, base plates, and connection components, providing accurately machined parts for the efficient assembly of steel frameworks. In the wind power industry, it is extensively applied to the machining of wind turbine tower sections and large-diameter flange components, ensuring outstanding dimensional accuracy and structural integrity under severe operating conditions such as high wind pressure and extreme temperature variations. In bridge engineering, the equipment is widely utilized for machining bridge girders, splice plates, and supporting structural members, producing robust and durable connections capable of withstanding long-term dynamic loading. As a result, it significantly enhances the structural safety, operational reliability, and service life of large-scale bridge infrastructure.
