How much does the Hwacheon MP+3706 cost?
Price estimate
We do not have a price for the Hwacheon MP+3706 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 MP+3706 is a heavy double-column machining center with a 6,000 x 3,100 mm (236.22 x 122.05 in) table rated 30 t (66,138 lb). It has 6,650 mm (261.81 in) of X travel, 4,500 mm (177.16 in) of Y, 1,000 mm (39.37 in) of Z and a 1,100 mm (43.31 in) W axis, with the columns 3,700 mm (145.67 in) apart. Among the MP+ models it is the shortest and the lightest.
Vertical reach comes from Z and W together. The listed distance from spindle centre to table runs from -270 to 1,830 mm (-10.63 to 72.05 in), so the 400 mm (15.75 in) ram can work low over a flat plate and still clear tall castings. W moves at 3 m/min (118 ipm) both in rapid and in feed, which makes it a positioning axis for setting the working height rather than one to cut with. X and Y rapid at 16 m/min (630 ipm) and Z at 12 m/min (472 ipm), and cutting feed is 10 m/min (394 ipm) on all three.
The spindle is a 7 / 24 taper BT-50 running to 4,000 rpm and rated 37 / 30 kW (49.92 / 40.23 hp). That speed range belongs to large face mills, boring and heavy drilling in cast iron and steel, not to high-speed finishing. The tool changer matches: 40 pockets as standard, with 60, 90 or 120 available, and tools up to Ø250 mm (Ø9.84 in) with neighbouring pockets empty, Ø130 mm (Ø5.12 in) with them full, 400 mm (15.75 in) long and 25 kg (55 lb). The coolant pump on the ram is rated 2.5 kW (3.35 hp) and draws from an 800 L (211 US gal) tank.
Installation is a project in its own right. The machine weighs 100,000 kg (220,462 lb), occupies 18,920 x 10,800 mm (744.88 x 425.2 in) and stands 7,780 mm (306.3 in) tall. It needs 130 kVA at 380V, 60Hz and air at 5 to 7 kg/cm² x 690 Nℓ/min. The control is a FANUC 31i-B.
The MP+3710 keeps this machine's spindle and magazine but stretches the table to 10,000 x 3,100 mm (393.7 x 122.05 in) at 40 t (88,184 lb).

Strengths & Limitations
Strengths
- 6,000 x 3,100 mm (236.22 x 122.05 in) table rated 30 t (66,138 lb) with seventeen 28H7 T-slots at 200 mm pitch
- Z travel of 1,000 mm (39.37 in) plus a 1,100 mm (43.31 in) W axis for tall parts
- BT-50 spindle rated 37 / 30 kW (49.92 / 40.23 hp) for large face mills and boring
- 40-tool magazine expandable to 60, 90 or 120 tools, taking tools up to Ø250 mm (Ø9.84 in) and 25 kg (55 lb)
- 3,700 mm (145.67 in) between columns for wide workpieces
Limitations
- Spindle speed tops out at 4,000 rpm, too slow for small-tool finishing
- Cutting feed is 10 m/min (394 ipm) on X, Y and Z, and W moves at only 3 m/min (118 ipm)
- 100,000 kg (220,462 lb) machine weight and an 18,920 x 10,800 mm (744.88 x 425.2 in) footprint demand a dedicated foundation
- Needs 130 kVA at 380V, 60Hz

Frequently Asked Questions
01
W adds 1,100 mm (43.31 in) of vertical stroke to the 1,000 mm (39.37 in) of Z, giving a spindle-centre-to-table range of -270 to 1,830 mm (-10.63 to 72.05 in). It moves at 3 m/min (118 ipm) in rapid and feed, so it is used to set the working height for each part.
02
