Korean machine tool builder Hwacheon has introduced the Hi-Tech 450 which features all-boxway guides, a gearbox-driven main spindle and 10-15 inch chuck options. UK distributor Ward Hi-Tech suggests this robust design strategy offers, for example, automotive subcontractors the opportunity to take large depths of cut, or aerospace subcontractors the capability to tackle tough materials.
The boxways on the Hwacheon Hi-Tech 450 are designed to maintain durability and precision even when performing prolonged machining operations. The ways are hand scraped and polished to high precision to reduce vibration and allow accurate feed during heavy cutting. Similarly, the single-frame bed structure eliminates heat distortion and absorbs vibration in the interests of surface quality and precision during high speed machining operations.
Instead of a single range direct drive for the main spindle, the standard automatic gearbox on the Hi-Tech 450 range provides extra, torque and power at lower speed while providing fast and efficient cutting at higher speeds. Furthermore, the transmission and spindle motor are separated to minimise heat and vibration interference.
The range features maximum turning diameters from 420 to 500 mm and turning lengths from 760 to 1,350 mm with chuck size options of 10, 12 and 15 inches. All models are available with up to 12 driven tools, full C-axis and Y-axis if required, while the A and B Series can also feature a sub-spindle. In total, some 26 different configurations of the Hwacheon Hi-Tech 450 are available: the standard model weighs in at 5.5 tonnes and the heaviest tops 8.8 tonnes.
Swing over bed on all models is 700 mm, while swing over saddle is 550 mm. All models are supplied with Fanuc 0i-TD CNC with Manual Guide and a 10.4-inch colour LCD screen as standard.
The Hwacheon Hi-Tech 450 turning centre range can match applications from basic part turning to high complexity component production via simultaneous control of multiple axes using the turn-mill function and C-axis spindle. With the addition of a sub-spindle, the main and the sub-spindles can work in sync to complete first and second operations on the same machine.
