Product features
1. The machine primarily consists of a machine bed, worktable, moving gantry, vertical ram-type power head, hydraulic system, pneumatic system, cooling system, centralized lubrication system, electrical control system, and automatic chip evacuation system.
2. In this machine series, the worktable and gantry are designed as separate structural units, with the gantry traveling along two supporting bases. This configuration significantly enhances machining stability, positioning accuracy, and load-bearing capacity, ensuring reliable performance during demanding drilling operations.
3. The machine is equipped with a high-quality cast-iron worktable manufactured from HT300 gray cast iron.
The machine bed and worktable are manufactured from premium HT300 gray cast iron and undergo two tempering heat-treatment cycles to relieve internal stresses. The bed and worktable adopt a separate structural arrangement to help suppress resonance generated during drilling operations and extend the service life of carbide cutting tools.
1. The automatic chip evacuation system and circulating cooling system reduce non-machining time and manual labor requirements. Operators primarily need to load and unload workpieces and replace drilling tools, improving overall production efficiency and simplifying routine operation.
2. The machine adopts a high-precision Taiwan-manufactured BT50 spindle with an internal cooling configuration, supporting the use of carbide drills for efficient machining. A pneumatic tool-clamping cylinder facilitates convenient and efficient tool changes. The high-power spindle motor is driven through a servo-controlled synchronous belt transmission system, supporting a broad spindle speed range to accommodate different machining requirements.
3. This CNC drilling machine is engineered around workpiece characteristics and required machining tolerances, featuring a compact structure and flexible operating capabilities. It efficiently accommodates different hole layouts, whether arranged in circular patterns or straight lines, and completes drilling operations with high speed and accuracy. Its practical configuration and reliable machining performance make it a cost-effective solution for precision plate processing.
The CNC gantry-type plate drilling machine is a robust industrial solution developed for the precise machining of plate-shaped workpieces and structural components. It is particularly suitable for processing flanges, discs, rings, flat plates, and similar components, provided that their material thicknesses remain within the machine's specified effective machining range.
In structural steel fabrication facilities, the machine performs precision drilling and milling on structural plates, connection plates, and related components, supporting accurate assembly and dependable structural connections. In the wind energy sector, it provides high-precision machining for wind turbine tower components and flange assemblies, helping ensure dimensional accuracy and structural reliability under demanding environmental conditions, including strong winds and temperature fluctuations. In bridge construction, the equipment processes bridge girders, support components, and associated structural parts, enabling the production of accurate, durable connections designed to withstand dynamic loads throughout the bridge's service life.
