Hwacheon i2
Complete machining with turn and mill
i Series
Built to order. Ask for lead time.
Overview
Ø600 x 1,100 mm turn-mill with a B-axis head and a second spindle
The i2 is Hwacheon's integrated turn-mill center: turning, milling, drilling and tapping on one machine, so complex parts finish in a single setup. Two 5,000 rpm A2-6 spindles with 8 inch chucks and Ø65 mm bar capacity face each other, and a 12,000 rpm HSK-T63 milling spindle rides a ±120° B axis with ±150 mm of Y travel. It cuts up to Ø600 mm by 1,100 mm long and holds 40 tools in its magazine (80 optional). The i2 S runs without a lower turret, the i2 ST adds a 12-station lower turret, and both run Hwacheon's HARMONY control on a FANUC 0i-TF Plus.

Features
- 01B-axis milling headThe HSK-T63 milling spindle runs to 12,000 rpm (20,000 rpm and CAPTO C6 optional) at 22 / 15 kW and 84 Nm. The B axis swings ±120° on a servo roller drive, positions in 0.0001° steps and clamps on a Curvic coupling in 5° steps.
- 02Two matched turning spindlesMain and second spindle are both A2-6, 5,000 rpm, 22 / 15 kW and 467 Nm, with 8 inch chucks, Ø65 mm bar capacity and 0.0001° indexing. A dual brake system gives high clamping force.
- 03±150 mm Y axisY travels ±150 mm at 36 m/min for off-center milling, drilling, tapping and multi-face work. X travels 630 mm and Z 1,165 mm, on linear guideways on every linear axis.
- 0440-tool magazineA chain-type magazine holds 40 HSK-T63 tools (80 optional), changed by swing arm with fixed-address selection. Tools can be loaded while the machine is cutting.
- 05Lower turret on the i2 STThe i2 ST adds a 12-station lower turret, offered for turning only or as a BMT 55 turnmill turret with a built-in motor: 15 kW, 47.7 Nm and 10,000 rpm live tools. Hwacheon states it turns, drills and mills while the milling spindle cuts.
- 06HARMONY controlHARMONY runs on FANUC 0i-TF Plus (31i-B5 Plus optional) with a 23.8 inch multi-touch screen. H-SIMUL iX interference checking and H-DRAW TC conversational programming are standard; real-time anti-collision is an option with the 31i-B5 Plus.
