Heavy steel fabrication, marine vessel structural frames, wind turbine hub bases, railway locomotive bogies, and mining crushers weigh anywhere from several to tens of metric tons. These massive cast-wrought components have severe raw forging tolerances, hard surface scale, and heavy stock allowance. Flipping these parts with cranes is hazardous, time-consuming, and risks gravitational sag deformation, while standard milling heads often suffer gear chipping and thermal breakdown under heavy shock loads.
Engineered specifically for heavy industrial extremes, Gong Yang’s heavy-duty CNC boring and milling heads handle power inputs over 42kW and cut under torque loads up to 1200 N.m. Built with high-strength alloy gears, heavy-load precision bearings, and forced oil-chiller circulation, they deliver continuous around-the-clock reliability through aggressive interrupted cuts and high-depth face milling. This robust capability allows large gantry machines to execute high-volume material removal and deep boring in fewer passes, slashing heavy-part production cycles.
