Custom 8m × 12.5m CNC Gantry Milling Machine Assembled; Large-Scale Component Machining Capability Enhanced
In August of this year, Tangshan Yuexin Machinery Manufacturing Co., Ltd. completed the assembly of a custom CNC gantry milling machine. The equipment features a machining envelope of 8 meters by 12.5 meters. Key installation steps—including the hoisting of the crossbeam and the positioning of the dual-beam overhead crane system—were executed in synchronization. Workshop personnel completed tasks such as column alignment and table leveling according to assembly blueprints, and the machine has now entered the power-on commissioning phase.
This machine is a large-span, heavy-duty CNC unit designed primarily for the milling and boring of large welded structures, castings, and forgings. Compared to conventional machining methods, gantry milling allows multiple surfaces to be machined in a single setup. This minimizes positioning errors caused by repeated handling and reclamping, resulting in significant improvements to both dimensional accuracy and machining efficiency. Consequently, manufacturers of heavy-duty components often view the specifications of their gantry milling equipment as a core indicator of their machining capabilities.
For Tangshan Yuexin Machinery, the installation of this new equipment is directly linked to its ability to secure export orders. The company has years of experience in export-oriented machining, with manufacturers of construction machinery and metallurgical/mining equipment in Europe and Southeast Asia regularly entrusting it with orders for non-standard parts. Overseas orders come with strict requirements regarding blueprints, tolerances, and delivery schedules; machining stability is the deciding factor in meeting deadlines. Furthermore, the batch processing of welded parts and castings demands high dimensional consistency, as even minor deviations can impact the client's subsequent assembly processes. To address this, the company has established rigorous standards for export inspection and anti-rust packaging to ensure product quality remains intact upon delivery to the customer.
The ability to handle such orders is the result of over twenty years of industry experience. The company operates CNC gantry machining centers, 6-meter floor-type milling and boring machines, CNC lathes, grinders, and large-scale welding equipment. It has long served heavy industry enterprises in the Beijing-Tianjin-Hebei region and mining equipment manufacturers nationwide, while maintaining partnerships with local firms such as Tangshan Ruifeng Steel. Its machining services encompass a wide range of operations, from blueprint-based manufacturing and reverse engineering from samples to single-unit prototyping and mass production.
The new gantry milling machine is currently undergoing commissioning. The company plans to ramp up the production capacity of its new equipment as soon as possible, focusing on securing custom manufacturing and export orders for large, heavy-duty components—such as mining equipment parts, construction machinery components, steel structure bases, and boom assemblies.
