Price estimate

Uncertain

We do not have a price for the Hwacheon Hi-TECH 650 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 Hi-TECH 650 is a 12-station turning center offered with two headstocks and three bed lengths, and it is the first size in the Hi-TECH range with a Y-axis version. It turns up to Ø600 mm (Ø23.6 in) over a Ø940 mm (Ø37.0 in) swing, with Ø620 mm (Ø24.4 in) clearing the saddle.

The 650A and 650B are effectively two machines on one bed. The 650A carries a 15 in chuck (18 in optional) on an A2-11 nose, a Ø132 mm (Ø5.2 in) bore that passes Ø117 mm (Ø4.6 in) bar, and a 37 / 30 kW (49.6 / 40.2 hp) motor rated at 3,071 Nm (2,265 lb-ft). It runs to 2,000 rpm, or 1,800 rpm with the 18 in chuck. The 650B steps up to a 21 in chuck, an A2-15 nose, a Ø185 mm (Ø7.3 in) bore for Ø165 mm (Ø6.5 in) bar and 45 / 37 kW (60.3 / 49.6 hp) with 4,108 Nm (3,030 lb-ft), at the cost of a 1,500 rpm ceiling. Each has a stronger motor option: 50 / 40 kW on the A and 60 / 50 kW on the B.

Turning length depends on bed and version: 1,000 to 1,108 mm (39.4 to 43.6 in) on the standard bed, 2,000 to 2,108 mm (78.7 to 83.0 in) on the L and 3,100 to 3,208 mm (122.0 to 126.3 in) on the XL. X travel is 360 mm (14.2 in) at 20 m/min (787 ipm). Z rapid is 24 m/min (945 ipm) on the standard bed, 20 m/min (787 ipm) on the L and 10 m/min (394 ipm) on the XL.

The MC and YMC versions add driven tools in BMT 75 holders, 3,000 rpm from a 7.5 / 5.5 kW (10.1 / 7.4 hp) motor with an 11 / 7.5 kW option, and a C axis indexing in 0.0001° steps. The YMC adds ±80 mm (±3.1 in) of Y travel at 10 m/min (394 ipm), enough for off-centre holes and milled flats without a second setup. Supply is 75 kVA, and the coolant tank holds 250 L (66 US gal) on the standard bed, 300 L (79 US gal) on the L and 370 L (98 US gal) on the XL.

Strengths & Limitations

Strengths

Choice of headstock: 650A with a 2,000 rpm A2-11 spindle, or 650B with a Ø185 mm (Ø7.3 in) bore and 4,108 Nm (3,030 lb-ft)
YMC version adds ±80 mm (±3.1 in) of Y travel to the driven tools and C axis
Optional motor upgrades to 50 / 40 kW (650A) or 60 / 50 kW (650B)
Three beds give up to 3,100 to 3,208 mm (122.0 to 126.3 in) of turning length on the XL

Limitations

The 650B gives up speed for its bore: 1,500 rpm against 2,000 rpm on the 650A
On the 650A the 18 in chuck option lowers the speed limit to 1,800 rpm
Z rapid falls to 10 m/min (394 ipm) on the XL bed
Driven tools reach 3,000 rpm, which limits small drills and end mills

Best For
