Product Advantages
Ultra-Heavy Load Capacity & Expansive Processing Range
GMC4220 as a type of heavy-duty gantry machine has a spacious workbench measuring 4000x1800 millimeters : A maximum load capacity of about 12 tonnes.[2] [6] Its X/Y/Z-axis movement range is 4200x2200x1000 mm; The gantry width is 2300 mm, and the clear passage height is 1400 mm. Therefore, it can process extra-large or ultra-heavy workpieces like wind-power hubs, large ship hull structures, and heavy-machine frame parts . Using a fixed beam-moving worktable structure to Optimize the utilization of Space, make work-piece placement and removal more convenient, and avoid conflicts with the machine while processing.
Enhanced Rigidity & Anti-Vibration Performance
The key components, such as the gantry beam, column and bed, are made from high-quality HT300 cast iron using integrated casting technology, subjected to an artificial ageing + natural ageing dual-stress relaxation process after production to enhance stability by approximately 20%.. A closed-box-type beam is used for construction; its cross-sectional dimensions are 460x460 mm², and the optimised internal triangle-reinforcing rib has significantly improved the stiffness and anti-shaking properties of the whole structure. Has a five-finger heavy-duty roll-linear guide system and pre-tensioned C3 grade precision ball screw for stable operation during long-duration of high-power cutting, maintaining good part shape precision.
High-Torque Spindle & Strong Heavy-Cutting Capability
Equipped with a 15kw power gear driven spindle(Optionally has 30kw), The maximum torque is 180Nm,and Spindle speed range can reach 40~6000r/min , specially designed for heavy cutting on high-strength material. Optional the tip of a 4:1 ZF reduction Gearbox is stable Power transmission and sufficient Cutting forces to ensure smooth Retrieval operation; In addition, It can help shorten Processing time.
Intelligent Operation & Low Maintenance Cost
It has been provided with a convenient-to-use CNC system (such as Fanuc, Siemens or GSK), which supports three-dimensional positioning (3D), DNC remote control processing and intelligent alarm prompt function to reduce operator's workload. The machine is equipped with a self-centralized oil supply device, double spiral chip conveyor and cold-air-cooling electronic box to extend the service lives of some parts and guarantee steady operation continuously for 24 hours. The modular Design, Simple Structure reduce the difficulty of maintenance and costs, Easily Accessible Spare Parts Shortens Downtime.
