The Hwacheon Hi-TECH 450 turning center with its small footprint provides space efficiency, while offering the largest turning diameter in its class of mid-size lathes at 500mm as well as turning length of 1350 mm, according to the company. With available chuck sizes of 10, 12 or 15, through-hole diameter of up to 132 mm and a range of options, including Y-axis machining, the center is designed to provide superior capability and machining flexibility. Hi-TECH 450 can be configured to ensure efficient setups for products including hydraulic valve, connectors, flanges or long shafts, particularly for the oil and gas industry
The turning center’s range of six machine configurations offers versatility for high speed or high torque operation. A high-powered spindle with integral motor offers a low-speed of 800 rpm for high-torque turning and maximum speed of 3,500 rpm with a rapid feed rate of 20/24m/min (X/Z). Turret indexing time to adjacent tools is 0.25sec, and turret capacity is 12 tools.
Hi-TECH 450 has an integrated 45-degree angle bed frame to minimize heat distortion and promote chip-shedding and work area access. The hand-scraped, wide-guide surface and the unique bed design absorb the vibration sufficiently, to ensure high degree of stability during hard turning. All guide surfaces are rectangular and incorporate tack guide to maintain rigidity and accuracy in prolonged operation.
The geared transmission system permits high-torque turning at low speed and also high-speed turning. The transmission is separate from the spindle motor avoiding the effects of transmission heat and the vibration on the spindle.
Hi-TECH450 has an optional Y axis, which can be easily added to MC/SMC type of the Hi-TECH 450, reducing cycle times for multi-function operation.

This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
