Hwacheon Hi-TECH 230B vs Hwacheon Hi-TECH 450B
Hwacheon vs Hwacheon · CNC Lathes
Summary
The Hwacheon Hi-TECH 230B and Hwacheon Hi-TECH 450B are two sizes of Hwacheon's turning center family, each offered in several bed lengths and in live-tool, Y-axis and sub-spindle versions. Turning diameter is nearly the same, Ø425 mm against Ø420 mm, so the difference is chuck, bar and spindle.
The 450B uses a 12 in chuck against 10 in, takes Ø89 mm (Ø3.5 in) bar against Ø81 mm (Ø3.2 in), and is rated 22 / 18.5 kW (29.5 / 24.8 hp) against 18.5 / 15 kW (24.8 / 20.1 hp), with an optional 26 / 22 kW motor. It also turns longer, 737 mm (29.0 in) against 379 mm (14.9 in) on the base bed, or 1,337 mm (52.6 in) against 1,119 mm (44.1 in) on the longest beds. The 230B spins faster, 3,500 rpm against 2,500 rpm.

Advantages
Hwacheon Hi-TECH 230B
- 3,500 rpm spindle against 2,500 rpm on the 450B
- Smaller 230A version reaches 4,500 rpm for small-diameter work
Hwacheon Hi-TECH 450B
- Ø89 mm (Ø3.5 in) bar capacity against Ø81 mm (Ø3.2 in)
- 12 in chuck against 10 in, with an 8 in sub-spindle on the (Y)SMC against 6 in
- 22 / 18.5 kW (29.5 / 24.8 hp) spindle, optional 26 / 22 kW, against 18.5 / 15 kW
- Up to 1,337 mm (52.6 in) turning length on the L bed against 1,119 mm (44.1 in) on the 230B XL
Verdict
Choose by chuck and bar size. The Hwacheon Hi-TECH 450B suits 12 in chuck work, bar up to Ø89 mm, longer shafts and heavy roughing with the optional 26 / 22 kW motor. The Hwacheon Hi-TECH 230B suits 10 in chuck parts and bar up to Ø81 mm, where its 3,500 rpm spindle gives better surface speed on smaller diameters and the XL bed still reaches 1,119 mm.
