The 2023 Hwacheon Hi-TECH 450B MC is a heavy-duty horizontal CNC turning center with live tooling, built on the rigid box-way construction that has made Hwacheon a trusted name in job shops, oil and gas, valve and general production environments. This B-type machine carries a 12" hydraulic chuck on an A2-8 spindle nose, a 4.13" spindle bore and 3.5" bar capacity, with a 27.56" swing over bed, 16.54" max turning diameter and 24.17" max turning length. A 30 HP (22 kW) main spindle drives through a 2-speed gearbox, 0-800 RPM low range for high-torque roughing and up to 2,500 RPM high range, with the transmission separated from the spindle to limit heat and vibration. Travels are X 11.02 / Z 31.1 inches with rapids of 787 / 945 IPM on an integrated 45-degree slant bed. The 12-station turret indexes in 0.25 sec and runs 5,000 RPM, 5 HP driven tools in axial and radial holders, with a C-axis indexing to 0.0001 deg for milling, drilling and rigid tapping. The Fanuc i Series Plus control includes Manual Guide i conversational programming. Equipment includes a programmable MT5 tailstock, tool presetter, chip conveyor, high-pressure coolant pump, bar feeder interface, signal light and work light. The machine weighs approximately 17,196 lbs and runs on 220V 3-phase power.
Compared with earlier Hwacheon turning centers such as the Hi-TECH 300 and Hi-TECH 400, the Hi-TECH 450 platform was engineered as a larger, stiffer mid-size lathe. It moves to an integrated 45-degree bed with wide rectangular box guideways for hard turning, isolates the gear transmission from the spindle motor for thermal stability, and offers the MC turnmill turret and C-axis that let one machine turn, mill, drill and tap a part in a single setup. Its 12-station live turret, generous swing and long Z stroke handle flanges, valve bodies and shafts that crowd smaller frames, and the current-generation Fanuc i Series Plus control with Manual Guide i makes programming at the machine faster than on older control generations. For a buyer, that means fewer setups, fewer secondary operations and a more capable machine, not just a newer one.
