Overview

The Hwacheon Hi-TECH 450B is a big-bore turning center with a 12 in chuck on an A2-8 nose, a Ø105 mm (Ø4.1 in) spindle bore and Ø89 mm (Ø3.5 in) bar capacity, running to 2,500 rpm. It turns up to Ø420 mm (Ø16.5 in) over a Ø700 mm (Ø27.6 in) swing, Ø550 mm (Ø21.7 in) over the saddle, and up to 737 mm (29.0 in) long on the standard bed or 1,337 mm (52.6 in) on the L bed.

The 450 is sold in three spindle sizes, and the B sits in the middle. The 450A has a 10 in chuck, Ø90 mm (Ø3.5 in) bore and Ø76 mm (Ø3.0 in) bar at 3,500 rpm. The 450C goes up to a 15 in chuck on an A2-11 nose, a Ø132 mm (Ø5.2 in) bore and Ø116 mm (Ø4.6 in) bar at 1,800 rpm, and as a 2-axis machine it turns up to Ø500 mm (Ø19.7 in). Front bearing size grows with them: Ø140 mm (Ø5.5 in) on the A, Ø160 mm (Ø6.3 in) on the B and Ø180 mm (Ø7.1 in) on the C. All three share a 22 / 18.5 kW (29.5 / 24.8 hp) spindle motor, with 26 / 22 kW (34.9 / 29.5 hp) as an option. For tube and large bar the B is the balance point: Ø89 mm (Ø3.5 in) of bar without dropping to the 1,800 rpm of the C.

The model comes as a 2-axis lathe or as MC, YMC and (Y)SMC versions, on standard and L beds. On the milling versions, turning length is 614 mm (24.2 in), or 1,214 mm (47.8 in) on the L bed, and the standard turning diameter is Ø254 mm (Ø10.0 in) against Ø295 mm (Ø11.6 in) on the 2-axis machine. The (Y)SMC sub-spindle has an 8 in chuck on an A2-6 nose and runs to 4,000 rpm; it is offered on the 450A and 450B only.

The table on this page does not give turret, axis travel, rapid, weight or control figures for the 450B, so ask Hwacheon for them before planning tooling or the installation.

Strengths & Limitations

Strengths

Ø89 mm (Ø3.5 in) bar capacity through a Ø105 mm (Ø4.1 in) bore
12 in chuck on an A2-8 nose with a Ø160 mm (Ø6.3 in) front bearing
Optional 26 / 22 kW (34.9 / 29.5 hp) spindle motor
Turning length up to 1,337 mm (52.6 in) on the L bed
Offered with Y axis and an 8 in sub-spindle in (Y)SMC form

Limitations

Spindle speed is 2,500 rpm on the 450B, limiting surface speed on small diameters
Milling versions lose turning length, down to 614 mm (24.2 in) on the standard bed
Standard spindle motor is 22 / 18.5 kW (29.5 / 24.8 hp) for a 12 in chuck
Bar above Ø89 mm (Ø3.5 in) needs the 450C, which drops to 1,800 rpm and loses the sub-spindle option

Best For

Bar and tube work up to Ø89 mm (Ø3.5 in) Chucked parts that need a 12 in chuck Long shafts up to 1,337 mm (52.6 in) on the L bed Complete machining on the (Y)SMC with an 8 in sub-spindle

Frequently Asked Questions

01 What separates the Hi-TECH 450A, 450B and 450C?

The 450A has a 10 in chuck, A2-8 nose, 3,500 rpm, Ø90 mm (Ø3.5 in) bore and Ø76 mm (Ø3.0 in) bar. The 450B has a 12 in chuck, A2-8, 2,500 rpm, Ø105 mm (Ø4.1 in) bore and Ø89 mm (Ø3.5 in) bar. The 450C has a 15 in chuck, A2-11, 1,800 rpm, Ø132 mm (Ø5.2 in) bore and Ø116 mm (Ø4.6 in) bar, and no sub-spindle version.

02 How does the Hi-TECH 450B compare with the Hi-TECH 350?

Both turn up to Ø420 mm (Ø16.5 in). The Hi-TECH 350 runs faster, at 5,000 rpm on the 350A and 4,000 rpm on the 350B, but takes bar only up to Ø76 mm (Ø3.0 in) and is listed in Y-axis versions. The 450B takes Ø89 mm (Ø3.5 in) bar in a 12 in chuck at 2,500 rpm and turns up to 737 mm (29.0 in) long.

03 How does the Hi-TECH 450B compare with the Hi-TECH 550?

The Hi-TECH 550 is the next size up: Ø590 mm (Ø23.2 in) turning diameter, 15 in or 18 in chucks on A2-11, Ø116 mm (Ø4.6 in) bar, 2,000 rpm and a 30 / 22 kW (40.2 / 29.5 hp) spindle, with beds up to 3,200 mm (126.0 in) of turning length. The 450B keeps a 12 in chuck, Ø89 mm (Ø3.5 in) bar and 2,500 rpm.

04 Is a sub-spindle available on the Hi-TECH 450B?

Yes, on the (Y)SMC version: an 8 in chuck on an A2-6 nose running to 4,000 rpm. The sub-spindle is offered on the 450A and 450B only. On milling versions turning length is 614 mm (24.2 in), or 1,214 mm (47.8 in) on the L bed.
