Overview

The Hwacheon Hi-Eco 21 is a box-way CNC lathe with an 8 in chuck on an A2-6 spindle nose. It is not in Hwacheon's current lineup, so this page serves someone looking at a used machine, and the figures here come from a resale listing rather than from Hwacheon. Treat every one of them as something to confirm on the machine itself.

The listed figures describe a mid-size lathe: a 4,000 RPM spindle with 15 kW (20 hp) and 350 Nm (258 ft-lb) of torque, Ø52 mm (2.05 in) bar capacity, a 12-station turret indexing in 0.3 sec, and rapids of 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z. The hardened and ground box ways favour steady roughing over rapid traverse. The listing gives the same 22.83 in for swing over bed and for maximum turning diameter, and the same 15.74 in for turning and machining length; on a real machine the turning diameter over the cross slide is normally smaller than the swing, so measure it before quoting a job.

The control is listed as Fanuc 0i-TF with Siemens 828D as an option, so check which one the machine in front of you carries. Weight is given as about 4,200 kg (9,259 lb). For a current machine of similar size, the Hi-TECH 200 in its A version has an 8 in chuck on the same A2-6 nose, 5,000 rpm and an 18.5 / 15 kW (24.8 / 20.1 hp) spindle.

Strengths & Limitations

Strengths

Listed spindle torque of 350 Nm (258 ft-lb) from a 15 kW (20 hp) motor
Hardened and ground box ways, suited to steady roughing
12-station turret listed at 0.3 sec per index
Ø52 mm (2.05 in) listed bar capacity on an A2-6 nose with an 8 in chuck

Limitations

Not in Hwacheon's current lineup, and the table comes from a resale listing, not the manufacturer
Listed maximum turning diameter equals the 22.83 in swing, so the real figure needs measuring
Spindle speed tops out at 4,000 RPM
Rapids of 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z

Best For

Used-machine buyers needing a box-way 8 in chucker Bar work up to Ø52 mm (2.05 in) per the listing General turning of steel parts at moderate speed

Frequently Asked Questions

01 Is the Hi-Eco 21 still made?

It is not in Hwacheon's current lineup, so it is normally found as a used machine. The figures on this page come from a resale listing for a Hi-Eco 21HS, not from Hwacheon, and should be checked on the machine before purchase.

02 What spindle does the Hi-Eco 21 have?

The listing gives an A2-6 nose with a 200 mm (8 in) chuck, 4,000 RPM, 15 kW (20 hp) and 350 Nm (258 ft-lb) of torque, with Ø52 mm (2.05 in) bar capacity. Run the spindle to full speed and check the chuck and drawtube before buying.

03 How does the Hi-Eco 21 compare with the current Hi-TECH 200?

The Hi-TECH 200 in its A version has an 8 in chuck on an A2-6 nose like the listed Hi-Eco 21, but runs to 5,000 rpm with an 18.5 / 15 kW (24.8 / 20.1 hp) spindle and turns up to Ø350 mm (Ø13.8 in). The Hi-Eco 21 is listed with box ways, 4,000 RPM and 15 kW (20 hp).

04 Which control does a used Hi-Eco 21 have?

The listing names Fanuc 0i-TF as standard and Siemens 828D as an option. Since either may be fitted, confirm the control on the machine itself, along with its options and alarm history, before agreeing a deal.
