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 KH50G is a small-pallet horizontal machining center with a big-machine spindle: a 500 × 500 mm pallet, a BT50 taper, and 901 / 730 N·m (664.6 / 538.4 ft-lbf) of torque from a gearbox drive that tops out at 4,500 rpm. Power is 18.5 / 15 kW (24.8 / 20.1 hp). Those numbers describe a machine set up to push large cutters slowly, not to run small tools fast.

Travels are 760 mm (29.9 in) in X, 705 mm (27.8 in) in Y and 650 mm (25.6 in) in Z, all larger than the pallet edge, so the spindle can reach around a fixture that overhangs the 500 mm square. Maximum workpiece weight is 800 kg (1,764 lb), and the table-load row reads 2 - 800, one figure for each of the two pallets on the 2-pallet shuttle APC.

Rapid traverse is 20 / 20 / 20 m/min (787 / 787 / 787 ipm). On a pallet this size that is modest, and it tells you where the cycle time goes: into the cut, not into positioning. Jobs made of many short moves and light cuts will not show this machine at its best. The 40-tool magazine has no listed expansion, another reason it suits a stable family of heavy parts more than a wide mix.

Set against the far larger KH1000, the torque figure stands out. The KH1000 lists 807 / 686 N·m (595.2 / 506 ft-lbf) from 26 / 22 kW (34.9 / 29.5 hp), but runs to 8,000 rpm. The KH50G gives up that top speed for low-end pull.

Strengths & Limitations

Strengths

901 / 730 N·m (664.6 / 538.4 ft-lbf) of spindle torque through a gearbox, on a BT50 taper
Travels of 760 x 705 x 650 mm (29.9 x 27.8 x 25.6 in) exceed the 500 × 500 mm pallet in every axis
800 kg (1,764 lb) maximum workpiece weight on a 500 mm pallet
2-pallet shuttle APC keeps loading outside the cutting time
More listed torque than the KH1000 (807 / 686 N·m), from a smaller 18.5 / 15 kW (24.8 / 20.1 hp) motor

Limitations

Spindle speed stops at 4,500 rpm, which rules out efficient small-tool and aluminium work
Rapids of 20 / 20 / 20 m/min (787 / 787 / 787 ipm) are slow for a pallet of this size; the HS10000 is listed at 50 / 50 / 50 m/min
40 tools, with no larger magazine in the table
18.5 / 15 kW (24.8 / 20.1 hp) limits metal removal once speed rises and torque falls away

Best For

Heavy milling and boring of steel and cast iron parts on a 500 × 500 mm pallet Large-diameter cutters and taps that need torque below 4,500 rpm Workpieces up to 800 kg (1,764 lb) Repeat production of a small part family with up to 40 tools

Frequently Asked Questions

01 How much torque does the KH50G spindle produce?

901 / 730 N·m (664.6 / 538.4 ft-lbf), with 18.5 / 15 kW (24.8 / 20.1 hp) of power. The spindle is driven through a gearbox, has a BT50 taper and a maximum speed of 4,500 rpm. WIA's table gives the two values in each row without saying which rating each one is.

02 What size parts fit the KH50G?

The pallet is 500 × 500 mm and the maximum workpiece weight is 800 kg (1,764 lb). Axis travels are 760 mm (29.9 in) in X, 705 mm (27.8 in) in Y and 650 mm (25.6 in) in Z. The table does not list a maximum workpiece diameter or height, so check the swing clearance for tall fixtures.

03 Does the KH50G have a pallet changer?

Yes. It is listed with a 2-pallet shuttle APC, and the table-load row reads 2 - 800, matching the 800 kg (1,764 lb) workpiece weight on each of the two pallets. The table gives no pallet change time.

04 How does the KH50G compare with the KH1000?

The KH1000 is far larger, with travels of 2,100 mm (82.7 in), 1,350 mm (53.1 in) and 1,400 mm (55.1 in) and a 60-tool magazine, and it runs to 8,000 rpm. Both rapid at 20 / 20 / 20 m/min. The KH50G has the higher torque figure, 901 / 730 N·m against the KH1000's 807 / 686 N·m.

05 Is the KH50G suitable for aluminium?

It will cut it, but the figures are not aimed at it. Maximum spindle speed is 4,500 rpm and rapids are 20 / 20 / 20 m/min (787 / 787 / 787 ipm), so small tools cannot reach useful surface speeds and non-cutting time is long. The 901 / 730 N·m of torque is where this machine earns its place.
