Overview

The Hwacheon Hi-TECH 750 is a heavy turning center for work up to Ø760 mm (Ø29.9 in) in diameter, with a Ø1,200 mm (Ø47.2 in) swing over the bed and turning lengths from 2,141 to 2,250 mm (84.3 to 88.6 in) on the standard bed up to 4,141 to 4,250 mm (163.0 to 167.3 in) on the XL. Its saddle clears Ø760 mm (Ø29.9 in) as well, so the full turning diameter is usable along the bed.

Like the Hi-TECH 650 it comes in A and B headstocks, but both are heavier here. The 750A has an 18 in chuck as standard (15 or 21 in optional), an A2-11 nose and a Ø132 mm (Ø5.2 in) bore, with 37 / 30 kW (49.6 / 40.2 hp) and 3,071 Nm (2,265 lb-ft), or 45 / 37 kW and 3,735 Nm as an option. It runs to 1,800 rpm, 1,700 rpm with the 21 in chuck. The 750B takes a 21 in chuck (24 in optional) on an A2-15 nose, a Ø185 mm (Ø7.3 in) bore for Ø164 mm (Ø6.5 in) bar, and 45 / 37 kW (60.3 / 49.6 hp) with 6,112 Nm (4,508 lb-ft). That is close to double the torque of the standard 750A, for 1,500 rpm, or 1,400 rpm with the 24 in chuck.

X travel is 430 mm (16.9 in) and the turret takes Ø80 mm boring bars alongside □32 mm shanks. Both axes rapid at 18 m/min (709 ipm) on the standard bed; Z slows to 14 m/min (551 ipm) on the L and 10 m/min (394 ipm) on the XL. The tailstock rides a Ø160 mm (Ø6.3 in) cylinder with an MT #6 quill.

MC and YMC versions use BMT 85 driven-tool holders, 11 / 7.5 kW (14.8 / 10.1 hp) and 3,000 rpm, with ±100 mm (±3.9 in) of Y travel on the YMC. Weight is 20,500 to 22,300 kg (45,194 to 49,163 lb) on the standard bed and reaches 27,500 to 29,300 kg (60,627 to 64,595 lb) on the XL. Plan for 85 kVA.

Turret takes Ø80 mm boring bars and □32 mm shanks

Limitations

Spindle speed is 1,800 rpm at most (750A), and 1,400 rpm on the 750B with a 24 in chuck
Z rapid falls to 10 m/min (394 ipm) on the XL bed
Bar capacity is Ø116 mm (Ø4.6 in) on the 750A; larger bar needs the 750B
At 20,500 to 22,300 kg (45,194 to 49,163 lb) for the standard bed, the foundation needs planning

Best For

Frequently Asked Questions

01 What separates the Hi-TECH 750A from the 750B?

The 750A: 18 in chuck, A2-11 nose, Ø132 mm (Ø5.2 in) bore, Ø116 mm (Ø4.6 in) bar, 37 / 30 kW (49.6 / 40.2 hp), 3,071 Nm (2,265 lb-ft), 1,800 rpm. The 750B: 21 in chuck, A2-15 nose, Ø185 mm (Ø7.3 in) bore, Ø164 mm (Ø6.5 in) bar, 45 / 37 kW (60.3 / 49.6 hp), 6,112 Nm (4,508 lb-ft), 1,500 rpm.

02 Which chucks can be fitted?

On the 750A the 18 in chuck is standard with 15 in and 21 in as options; the 21 in chuck lowers the speed limit to 1,700 rpm. On the 750B the 21 in chuck is standard and a 24 in chuck is optional, which lowers the limit from 1,500 rpm to 1,400 rpm.

03 How does the Hi-TECH 750 compare with the Hi-TECH 850?

The Hi-TECH 850 turns larger, Ø920 mm (Ø36.2 in) for turning lengths up to 385 mm (15.2 in), and longer, up to 5,100 mm (200.8 in) on its XL bed. The Hi-TECH 850 has a single 24 in chuck headstock at 1,500 rpm. Rapids are 18 / 18 m/min (709 / 709 ipm) in X and Z on the 750 against 10 / 12 m/min (394 / 472 ipm) on the Hi-TECH 850.

04 What are the bed options?

Three. Z travel is 2,350 mm (92.5 in), 3,350 mm (131.9 in) or 4,350 mm (171.3 in), and tailstock travel 2,300 mm (90.6 in), 3,300 mm (129.9 in) or 4,300 mm (169.3 in). The machine is 6,560 mm (258.3 in) long on the standard bed, 7,560 mm (297.6 in) on the L and 8,860 mm (348.8 in) on the XL, 3,060 mm (120.5 in) wide.

05 How big is the coolant tank?

380 L (100 US gal) on the standard bed, 450 L (119 US gal) on the L bed and 560 L (148 US gal) on the XL bed. With long roughing cycles at up to 45 / 37 kW (60.3 / 49.6 hp), size the chip handling to match.
