The Hi-TECH 450 horizontal turning center from Hwacheon Machinery America has a 500mm turning diameter and 1,350mm turning length. A spindle with integral motor offers a low speed of 800 rpm for high-torque turning and a maximum speed of 3,500 rpm. The rapid feed rate is 20 m/min. for the X-axis and 24 m/min. for the Z-axis. Turret indexing time to adjacent tools is 0.25 seconds, and turret capacity is 12 tools.
The machine has an integrated 45 degree bed frame to minimize heat distortion and promote chip shedding and access to the work area, according to the company. The transmission is separate from the spindle motor to avoid the negative impact of transmission heat and vibration on the spindle. Six machine configurations are available. A Y-axis is optional.

turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
