China Gantry Machining Center WMC-Ⅱ 28 Series - High Precision from Leading Suppliers and Factory
Product Performance
The WMC-Ⅱ 28 Series moving-beam fixed column gantry machining center features a moving worktable structure and is primarily composed of a base, worktable, columns, beam, connecting beam, ram, slide, pneumatic system, lubrication system, hydraulic system, cooling system, safety protection, guideway protection, CNC system, electrical control, and other components.
The main structural components—including the base, worktable, columns, beam, connecting beam, ram, and slide—are designed using 3D finite element optimization. These components are made of high-quality HT300 cast iron (with the ram constructed from QT600), incorporating non-ferrous metals in accordance with the European "M"eehanite quality standard. They are manufactured using the resin sand casting process and undergo comprehensive heat treatment (including secondary aging after rough machining) to eliminate casting and cutting residual stresses. This ensures excellent rigidity, freedom from deformation, and overall strength, stiffness, and stability of the machine.
- This machine series is with solid double-column structure of fixed gantry frame, moving table and vertical lifting of crossbeam. The lower part of the column closely connects with the bed and the upper part lines with composite beams, which can ensure high precision and high rigidity.
- The columns and beams are rectangular cross section with structurally optimised design and reasonable reinforcement for good rigidity, which could withstand heavy cutting but keep high precision in long term.
- The main parts such as bed, table, column and beam are all made of integrated whole casting structure. Sufficient quantities and thickness of metre rib and reinforcement plate are scattered inside machine bed and column to ensure machine rigidity.
- All parts are with heat and aging treatment. With second tempering to remove internal stress after rough machining, it can ensure the stability of the machine accuracy and durability.

Frequently Asked Questions
1. What materials are used to construct the main components of the WMC-Ⅱ 28 Series?
The main structural components (base, worktable, columns, beam, connecting beam, and slide) are made of high-quality HT300 cast iron, while the ram is constructed from QT600. These parts are produced using the resin sand casting process in accordance with European Meehanite quality standards.
2. How is structural stability and precision maintained over long-term use?
All major cast parts undergo thorough heat treatment, including a secondary tempering and aging process after rough machining. This effectively eliminates internal casting and cutting stresses, ensuring high precision, rigidity, and resistance to deformation.
3. What are the standard spindle specifications for this series?
The standard configuration features a high-speed BT50 spindle capable of 8000 rpm, paired with a main drive 6000 rpm 2-speed gearbox. It also includes a constant temperature cooling system for both the spindle and the gearbox.
4. What is the maximum load capacity of the worktable?
The maximum table load depends on the specific model length: 12,000 kg for the 28x40 model, 15,000 kg for the 28x50 model, 18,000 kg for the 28x60 model, and up to 24,000 kg for the 28x80 model.
5. What optional configurations are available for head and tool management?
Optional configurations include a fully automatic exchangeable head, a 45° fully automatic universal head, and tool magazines with capacities of either 40pcs or 60pcs (available in vertical/horizontal exchange or chain type configurations).
6. What chip conveyor system is standard on the WMC-Ⅱ 28 Series?
The standard configuration comes equipped with a highly efficient double screw and horizontal chain type chip conveyor system to ensure clean and continuous operation.
