Overview
400 mm two-pallet horizontal with a 15,000 rpm spindle and 60 m/min rapids
The AF-4 is Hwacheon's compact horizontal machining center for 400 mm pallets. Hwacheon builds it for mass production, small and medium batches and prototypes, including automotive and aerospace parts, and its catalog shows semiconductor sample parts. It travels 565 / 645 / 645 mm at 60 m/min on linear guides, runs a BBT-40 built-in spindle to 15,000 rpm with 303 Nm (20,000 rpm optional), and indexes the B axis in 0.0001 degree steps. A hydraulic APC with a setup station handles two pallets of 400 kgf each, and the ring magazine holds 40 tools, with 60 as an option.

Features
- 01Built-in 15,000 rpm spindleThe standard built-in motor spindle runs to 15,000 rpm with 37 kW and 303 Nm maximum; the 20,000 rpm option has 37 kW and 221 Nm. It has four front bearings, oil jets cool the bearings, and the motor and spindle are jacket-cooled to limit heat displacement.
- 0260 m/min on linear guidesAll three linear axes run on linear guides at 60 m/min rapid, on a frame Hwacheon designed for 1G acceleration and deceleration with a heavy fixed base and a light moving structure.
- 03Rotary table to 0.0001 degreeThe B-axis table indexes in 0.0001 degree steps on a dual lead worm gear, with hydraulic clamping and 34 rpm rapid rotation.
- 04Two-pallet APC with setup stationA hydraulic APC carries two 400 x 400 mm pallets at 400 kgf each, for workpieces up to Ø630 x 900 mm. The setup station has a rotary door so a crane can reach fixtures and parts.
- 05Chip and coolant handlingTwelve ceiling nozzles and the spindle head wash chips off the part and table, bed flushing and an inclined internal cover carry them out, and the coolant tank holds 960 liters. Coolant through spindle is optional at 3 or 7 MPa.
- 06Fluid lines for automationHydraulic (6 port) and pneumatic (2 port) fluid lines for jig and fixture clamping in automated setups are an option.
