How much does the Hwacheon TTC-10 cost?

Price estimate

Uncertain

We do not have a price for the Hwacheon TTC-10 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 TTC-10 is a two-chuck, two-turret turning center for short chucked parts: two 10 in chucks, 12 + 12 turret stations and a FANUC 0i-TF Plus control with 2 paths. Maximum turning diameter is Ø400 mm (Ø15.7 in), the standard turning diameter Ø320 mm (Ø12.6 in), and maximum turning length only 203 mm (8.0 in), so the machine is laid out for flanges, hubs, gear blanks and similar work rather than shafts.

The two paths let both turrets cut at the same time, which is where a machine of this layout earns its floor space: one operation on each side, or the same part on both, with one operator loading. The listed spindle has an A2-8 nose, a Ø77 mm (Ø3.0 in) bore and Ø59 mm (Ø2.3 in) bar capacity, and runs to 2,000 rpm. Spindle power is 18.5 / 15 kW (24.8 / 20.1 hp), with 22 / 18.5 kW (29.5 / 24.8 hp) as an option. The front bearing is Ø120 mm (Ø4.7 in).

Axis strokes are short to match the work: 215 mm (8.5 in) of X and 230 mm (9.1 in) of Z, with rapids of 30 / 30 m/min (1,181 / 1,181 ipm). Turret indexing is 0.4 sec/step, and the turrets take □25 mm shanks and Ø50 mm boring bars. The table lists no driven tools, so cross holes and flats need a second machine.

The machine weighs 9,500 kg (20,944 lb) on a footprint of 3,000 x 2,840 mm (118.1 x 111.8 in), stands 2,046 mm (80.6 in) high and needs 75 kVA. The coolant tank holds 380 L (100 US gal). Compared with a single-spindle model such as the Hi-TECH 230B, which reaches 3,500 rpm and Ø81 mm (Ø3.2 in) of bar on the 230B, the TTC-10 gives up speed and bar size in exchange for two working spindles.

Strengths & Limitations

Strengths

Two 10 in chucks and 12 + 12 turret stations under a 2-path control, so two operations run at once
30 / 30 m/min (1,181 / 1,181 ipm) rapids on short 215 mm (8.5 in) X and 230 mm (9.1 in) Z strokes
Ø400 mm (Ø15.7 in) maximum turning diameter from a compact 3,000 x 2,840 mm (118.1 x 111.8 in) footprint
Spindle power of 18.5 / 15 kW (24.8 / 20.1 hp), with 22 / 18.5 kW (29.5 / 24.8 hp) optional
Ø77 mm (Ø3.0 in) spindle bore on an A2-8 nose

Limitations

Maximum turning length is 203 mm (8.0 in), which rules out shafts
Spindle speed tops out at 2,000 rpm, low for small diameters and aluminium
Bar capacity is Ø59 mm (Ø2.3 in), so most work will be chucked blanks
No driven tools appear in the table, so milled features need another machine

Best For

Flanges, hubs and discs up to Ø400 mm (Ø15.7 in) Two-operation chucking work finished in one cycle Volume runs of short parts under 203 mm (8.0 in) long Cells where one operator loads both chucks

Frequently Asked Questions

01 What size parts does the TTC-10 handle?

Up to Ø400 mm (Ø15.7 in) in diameter, with Ø320 mm (Ø12.6 in) given as the standard turning diameter, and up to 203 mm (8.0 in) long. Swing over the bed is Ø500 mm (Ø19.7 in). Both chucks are 10 in.

02 How do the two turrets work on the TTC-10?

There are 12 + 12 turret stations and the FANUC 0i-TF Plus control runs 2 paths, so each turret is programmed on its own path and both can cut at once. Each turret indexes at 0.4 sec/step and takes □25 mm shanks and Ø50 mm boring bars.

03 What spindle speed and power does it have?

2,000 rpm maximum on an A2-8 nose, with 18.5 / 15 kW (24.8 / 20.1 hp) as standard and 22 / 18.5 kW (29.5 / 24.8 hp) as an option. The spindle bore is Ø77 mm (Ø3.0 in) and bar capacity Ø59 mm (Ø2.3 in).

04 What does the TTC-10 need on the shop floor?

A 3,000 x 2,840 mm (118.1 x 111.8 in) footprint with 2,046 mm (80.6 in) of height, a floor for 9,500 kg (20,944 lb) of machine and a 75 kVA supply. The coolant tank holds 380 L (100 US gal).
