Introduction of CNC milling machine:
This CNC milling machine combines modern CNC technology with precision machining processes. Fixed table milling bed base is constructed of high-strength cast iron, ensuring its rigidity and vibration resistance. The gantry frame is constructed of welded steel plates, while the worktable, slide, and ram are molded using resin sand, further enhancing the machine's precision and stability. Equipped with high-precision spindle bearings and a hydraulic cylinder balancing system, this machine ensures smooth movement of the ram and milling head, improving machining accuracy.
This CNC milling machine is suitable for rough and fine machining of complex shapes on large machine bases, large housings, and various rotary parts. Large gantry milling machines is also particularly well-suited for machining large precision parts in industries such as shipbuilding, power generation, energy, transportation, mining, metallurgy, and engineering machinery.
Features of Traveling bridge boring machine:
▲ The traveling bridge boring machine is available in two types: gantry and table. Each type can be further divided into fixed-beam and adjustable-beam models, depending on user requirements.
▲ Users can choose between linear guides (GM series) or hydrostatic guides (XK series) for the traveling bridge boring machine based on their processing needs.
▲ The main drive features a two-speed continuously variable transmission, achieving high torque at low speeds and constant power at high speeds. The traveling bridge boring machine can meet the diverse process requirements of both roughing and finishing.
▲ When equipped with appropriate accessories, the traveling bridge boring machine can perform various machining operations, including milling, boring, drilling (drilling, reaming, and tapping), on multiple workpiece surfaces (excluding mounting surfaces) in a single clamping. This eliminates errors caused by multiple clamping, positioning, zeroing, alignment, and tool setting operations, improving machining accuracy and efficiency.
▲ A variety of accessories with different functions can be added to meet user requirements.
▲ The accessories feature automatic indexing and automatic exchange functions. The large gantry milling machines can also be equipped with an optional tool magazine for automatic tool changing.

Our large gantry milling machines offer advantages over conventional CNC milling machine:
1.Our large gantry milling machines utilize CAD-optimized, modular designs, allowing for flexible configuration of accessories such as milling heads, tool magazine capacity, and cooling systems based on user needs, providing a truly customized solution.
2.Conventional large gantry milling machines have limited load capacity, which can easily lead to deformation and reduced precision when machining large workpieces. Our large gantry milling machines feature a high-load-bearing table, a sturdy bed and column structure, and a ball screw drive, ensuring smooth crosshead movement and long-term stable machining accuracy.
3.Conventional CNC milling machine are prone to low efficiency and insufficient torque during slow, heavy-duty machining. Our large gantry milling machines, equipped with a high-speed spindle unit and precision planetary gearbox transmission, not only offer high torque and efficiency, but also maintain stability and efficiency even in slow, heavy-duty machining conditions, resulting in machining performance far exceeding that of conventional machine tools.
