China Gantry Machining Center GMC40250FMD - Reliable Suppliers and Factory for Precision Engineering Solutions
Product Performance
The GMC40250fmd Double Gantry Moving Column Gantry Machining Center is one of the gantry machining center series products independently developed by our company.
The basic structure of this machine tool is a fixed-beam gantry frame with a stationary worktable. The gantry frame moves to complete the X-axis feed. Two gantry frames are arranged in the same direction along the X-axis (with the two gantries oriented in parallel), each equipped with independent Y/Z axes and spindle systems, controlled by two separate CNC systems. This allows for independent control of the two gantry frames. Safety interlock switches are installed between the two gantry frames to strictly control the minimum distance between them, ensuring safe and reliable operation.
The Y/Z axes on both gantry frames operate as follows: the sliding carriage moves laterally along the heavy-duty linear roller guide rail on the beam to complete the Y-axis feed; the ram moves vertically along the guide rail on the sliding carriage to complete the Z-axis feed. Under the control of their respective CNC systems, each can independently achieve three-axis three-linkage motion. The moving column CNC gantry milling machine with a moving gantry frame is a typical tool-moving machine tool, featuring advantages such as consistent moving component mass, relatively large workpiece weight, and a small floor space, making it a mainstream structural form for large machine tools.
The main characteristics of this machine tool are its super-large gantry frame, excellent rigidity, strong vibration absorption capacity, large machining range, good stability, and superior dynamic performance. The machine is capable of various machining functions, including milling, boring, drilling (drilling, reaming, tapping), threading, and spot-facing. It can be equipped with fully automatic right-angle milling heads, extension heads, universal angle heads, and other attachments, effectively expanding the machining range of the machine tool. Multiple hole systems and surfaces on a part can be machined in a single setup.
The structure and technology of this product are mature, and its quality is stable. It is suitable for various mechanical processing fields such as automotive, shipbuilding, printing, packaging, textiles, military, and mold manufacturing. The machine features high efficiency, high precision, and high rigidity, making it an ideal choice for high-efficiency, mass production of parts in enterprises.
- It is the preferred processing equipment for engineering machinery, rolling stock, mining equipment, turbines, ships, military, nuclear power, large-scale environmental protection equipment and other industrial sectors.
- The gantry-moving CNC gantry machine belongs to the typical tool-moving machine, which has the advantages of fixed quality of moving parts, relatively unlimited weight of the workpiece, small footprint, etc., and it is the mainstream structural form of large-scale machine.
- Combined with a variety of cannons and accessories, it can expand the machining range and improve the machining efficiency, realising multi-face and multi-process machining.
- It can realise the alternating machining of multiple working stations, and at the same time, it can also realise the synchronous and efficient machining of oversized workpieces, and achieve the arbitrary switching of multiple machining modes.
