The Hwacheon HI-TECH-400A is a heavy-duty CNC horizontal turning center with a reputation for rigid, dependable big-part turning that has made the Hi-TECH line a staple in production and job-shop environments. This 2011 machine pairs a 15-inch chuck with an A2-11 spindle nose, a 5.2-inch spindle bore, and a 4.56-inch bar capacity, giving shops the room to hold and turn large, demanding workpieces. The spindle delivers up to 1,800 RPM driven by a 30 HP motor, while the box-way bed provides the mass and stability needed for heavy cuts and sustained accuracy. The work envelope covers a 23.62-inch swing over bed, up to a 14.96-inch maximum cutting diameter, and a 27.95-inch maximum cutting length, with X and Z travels of 11.02 inches and 32.28 inches. A 12-station turret, tailstock support, and a Fanuc control round out a straightforward, production-ready package for shafts, flanges, and other large-diameter parts.
Compared to the earlier Hwacheon Hi-TECH 400, the HI-TECH 400A advances the platform with a more rigid box-way feed structure and refined thermal management that hold precision through long, heavy cutting cycles, improvements the base Hi-TECH 400 could not match under the same loads. The 400A 30 HP spindle class and A2-11 large-bore configuration expand the range of stock a shop can run versus the lighter earlier build, and the updated Fanuc control brings faster, more intuitive programming and setup. For a buyer, that means a meaningfully more capable heavy-turning machine, more rigidity, more spindle authority, and a more modern control, at a used-machine investment rather than the cost of new.
