Estimated price range
Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from Hyundai WIA. Configuration moves it a long way.
Overview
The Hyundai WIA KH400 is a compact twin-pallet horizontal machining center on 400 x 400 mm (15.7 x 15.7 in) pallets, with a 15,000 RPM BT40 built-in spindle and 60 m/min (2,362 ipm) rapids. Hyundai WIA does not show it in the current lineup, so the listed figures here are for judging a used machine.
Travels are 500 mm (19.7 in) in X, 560 mm (22.0 in) in Y and 500 mm (19.7 in) in Z. Y is the longest axis, which favours a tall tombstone with parts stacked on each face. The machine weighs 18,000 kg (39,683 lb), heavy for this envelope, and it runs on linear roller guides.
Spindle power is 22/18.5 kW (30/25 hp). No torque row is listed, but 15,000 RPM on a BT40 taper points to aluminium and small-tool work more than to heavy steel roughing. The chain-type ATC holds 60 tools, enough to keep two different jobs tooled up across the 2-pallet APC.
The B axis deserves a check on any used example. Standard indexing is 1°, with 0.001° listed as an option, and a 1° table cannot be set to an arbitrary angle. Positioning accuracy is listed as ±0.004 mm (±0.00016 in) and repeatability as ±0.002 mm (±0.00008 in). The control is a FANUC 0i-MF Plus. One size up, the KH500 lists 500 x 500 mm (19.7 x 19.7 in) pallets, a BT50 spindle at 12,000 RPM and 26,000 kg (57,320 lb).

Strengths & Limitations
Strengths
- 15,000 RPM built-in BT40 spindle with 22/18.5 kW (30/25 hp)
- 60 m/min (2,362 ipm) rapid traverse on linear roller guides
- 60 tools in a chain-type ATC
- Listed positioning accuracy of ±0.004 mm (±0.00016 in) and repeatability of ±0.002 mm (±0.00008 in)
- 560 mm (22.0 in) of Y travel over a 400 x 400 mm (15.7 x 15.7 in) pallet
- 2-pallet APC for loading while the spindle cuts
Limitations
- Not in Hyundai WIA's current lineup
- B-axis indexing is 1° as standard; 0.001° is an option that a given used machine may not have
- X and Z travels of 500 mm (19.7 in) limit part and fixture size
- No spindle torque or pallet load figure is listed
- At 18,000 kg (39,683 lb) it needs a substantial floor for a machine of this pallet size

Frequently Asked Questions
01
The pallets are 400 x 400 mm (15.7 x 15.7 in) and the machine has a 2-pallet APC. Travels are 500 mm (19.7 in) in X, 560 mm (22.0 in) in Y and 500 mm (19.7 in) in Z. Rapid traverse is listed at 60 m/min (2,362 ipm).
02
Not as standard. The B axis is listed with 1° indexing, and 0.001° indexing is an option. On a used KH400, check which table is fitted, because parts with compound or odd angles need the finer option.
03
A built-in spindle motor on a BT40 taper, with a maximum of 15,000 RPM and 22/18.5 kW (30/25 hp). No torque figure is listed. The tool changer is a chain type holding 60 tools.
04
The KH400 has 400 x 400 mm (15.7 x 15.7 in) pallets, a BT40 spindle at 15,000 RPM and 60 m/min (2,362 ipm) rapids, and weighs 18,000 kg (39,683 lb). The KH500 lists 500 x 500 mm (19.7 x 19.7 in) pallets, a BT50 spindle at 12,000 RPM with 30/22 kW (40/30 hp), 50 m/min (1,969 ipm) rapids and 26,000 kg (57,320 lb).
