DXH28-2204WZ High-Precision Moving Gantry Machining Center-Qi Fa (Jiangsu) Machinery Co., Ltd.

DXH28-2204WZ High-Precision Moving Gantry Machining Center is designed for high-precision and high-efficiency machining of large components. Its rigid gantry structure and coordinated mechanical, electronic and hydraulic systems provide stable machining performance and long-term accuracy retention. The machine supports multiple operations after a single workpiece setup, including plane, step, slot, complex surface, cavity, drilling, reaming and rigid tapping. Modular configurations allow different travels, tool magazines and automatic or manual angle milling heads according to machining requirements.

DXH28-2204WZ High-Precision Moving Gantry Machining Center is widely used for:

· Bridge and railway equipment components
· Energy and power equipment parts
· Shipbuilding components
· Chemical equipment manufacturing
· Large mechanical structure machining

Thermally Stable Spindle System
The spindle bearing assembly and transmission system use professional imported components with a constant-temperature cooling circuit, helping stabilize spindle and guideway temperatures and reduce thermal deformation.

Precision Ball Screw Transmission
The ball screws use fixed-end support with imported precision bearing assemblies and bidirectional pre-stretching, improving feed rigidity, positioning performance and service life.

High-Precision X-Axis Guideways
The X-axis uses four sets of heavy-duty linear roller guideways, providing low friction, high sensitivity, low vibration at high speed and stable movement at low speed.

Rigid Y-Axis Guide Structure
The Y-axis crossbeam uses two sets of heavy-duty linear guideways in a stepped arrangement with a large span, providing strong resistance to bending and torsional deformation.

Multi-Process Machining Capability
The machine can continuously perform plane, step, slot, complex surface, cavity, drilling, reaming and rigid tapping operations after a single workpiece setup, reducing repeated positioning and improving machining efficiency.
