How much does the Hwacheon VT-4500 cost?
Price estimate
We do not have a price for the Hwacheon VT-4500 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Hwacheon VT-4500 is a very large ram-type vertical lathe: a Ø4,500 mm (Ø177.2 in) table, Ø5,000 mm (Ø196.9 in) maximum turning diameter, 2,500 mm (98.4 in) maximum turning height and a 40,000 kgf (88,184 lb) table load. Like the VT-3000 it is listed only in milling form, the VT-4500 (Milling), with a SIEMENS 840D sl control.
What separates it from the VT-3000 is the table drive. The VT-4500 table runs at 1 ~ 50 rpm in 2 steps, half the top speed of the smaller machine, and in exchange the 129 / 105 kW (173.0 / 140.8 hp) motor and double-pinion drive deliver 162,268 Nm (119,689 lb-ft). On a Ø5,000 mm part, 50 rpm is still a fast surface speed at the rim; the figure that limits the work is torque, and this machine has more of it for heavy cuts at large radius. The VT-3000, for comparison, gives 100,299 Nm (73,981 lb-ft) and carries 30,000 kgf (66,138 lb).
To reach the larger diameter the ram stroke on X is -250 ~ 4,100 mm (-9.8 ~ 161.4 in). Z is 1,500 mm (59.1 in) on a □350 mm (□13.8 in) ram, and the cross rail travels 2,000 mm (78.7 in) on W. Rapids are 6 / 6 / 0.5 m/min (236 / 236 / 20 ipm) on X, Z and W. Milling uses a 38 / 30 kW (51.0 / 40.2 hp) BT-50 spindle to 1,500 rpm, and the C axis indexes in 0.001° steps at up to 0.5 rpm with 0 ~ 180 deg/min of cutting feed.
The 12-tool magazine takes □50 mm turning tools and milling tools up to 415 mm (16.3 in) long and 100 kgf (220 lb), Ø180 mm (Ø7.1 in) with adjacent pockets full or Ø350 mm (Ø13.8 in) with them empty. Planning starts with the building: 140,000 kg (308,644 lb) of machine, 9,800 mm (385.8 in) of height and 11,500 x 7,500 mm (452.8 x 295.3 in) of floor, fed by 200 kVA at 380 V, 60 Hz and 5 ~ 7 bar air.

Strengths & Limitations
Strengths
- Turns parts up to Ø5,000 mm (Ø196.9 in) on a Ø4,500 mm (Ø177.2 in) table
- Table load of 40,000 kgf (88,184 lb)
- 162,268 Nm (119,689 lb-ft) of table torque from a 129 / 105 kW (173.0 / 140.8 hp) motor
- X stroke of -250 ~ 4,100 mm (-9.8 ~ 161.4 in) on a □350 mm (□13.8 in) ram

Frequently Asked Questions
01
The VT-4500 has a Ø4,500 mm (Ø177.2 in) table and turns Ø5,000 mm (Ø196.9 in), against Ø3,000 mm (Ø118.1 in) and Ø4,000 mm (Ø157.5 in) on the VT-3000. Against the VT-3000 it carries 40,000 kgf instead of 30,000 kgf, gives 162,268 Nm of torque instead of 100,299 Nm, and tops out at 50 rpm instead of 100 rpm.
02
1 ~ 50 rpm in 2 steps, from a 129 / 105 kW (173.0 / 140.8 hp) motor through a double-pinion drive, with 162,268 Nm (119,689 lb-ft) of torque. On the largest diameters even 50 rpm gives a high surface speed, so torque rather than speed sets the limit.
03
A 38 / 30 kW (51.0 / 40.2 hp) milling spindle with a BT-50 taper, running to 1,500 rpm. The C axis indexes in 0.001° steps, turns at up to 0.5 rpm and feeds at 0 ~ 180 deg/min. Milling tools can weigh up to 100 kgf (220 lb).
04
A foundation for 140,000 kg (308,644 lb), 9,800 mm (385.8 in) of height and 11,500 x 7,500 mm (452.8 x 295.3 in) of floor. Power is 200 kVA at 380 V, 60 Hz, and the air supply 5 ~ 7 bar.
