Heavy-duty gantry machining center
The GMC4220 gantry machining center is designed to machine large-scale and heavy components with exceptionally high strength. The moving-table, fixed-beam structure with a high-torque spindle supports the production of large parts for power equipment.
Product description
The heavy-duty gantry machining center GMC4220 is a high-performance CNC machine designed for machining large-scale and heavy components with exceptionally high strength. It features a fixed-beam and moving-worktable structure, a high-torque spindle, and enhanced anti-vibration properties, which overcome problems such as insufficient load-bearing capacity, poor stability during heavy cutting, and the limited workspace of typical heavy machines. It is suitable for machining hard metals, such as alloy steel, mold steel, titanium alloys, and carbon steel. It provides reliable, high-performance, and stable machining solutions for the machinery industry, shipbuilding, large-scale power equipment, and the production of large-scale structural parts.
