The Hwacheon Hi-Tech 450 horizontal turning center offers a 500-mm turning diameter and 1,350-mm turning length in a small footprint. Applications include hydraulic valves, connectors, flanges and long shafts, particularly for the oil and gas industries.
A high-powered spindle with integral motor offers a low speed of 800 rpm for high-torque turning and a maximum speed of 3,500 rpm with rapid feed rates of 20 m/min. in the X axis and 24 m/min. in the Z axis. The turret capacity is 12 tools, and indexing time to adjacent tools is 0.25 sec. A geared transmission system enables high-torque turning at low speeds as well as high speed turning. The transmission is separate from the spindle motor to reduce heat and vibration.
The turning center has an integrated 45-degree angle bed frame said to minimize heat distortion and promote chip-shedding and work area access. According to Hwacheon, the hand-scraped guide surface and bed design absorb vibration and increase stability during hard turning. All guide surfaces are rectangular and incorporate tack guide to maintain rigidity and accuracy in prolonged operation. Chuck sizes of 10, 12 or 15 are available, with a through-hole diameter ranging to 132 mm. The machine can be equipped with an optional Y axis for multi-function operation.
