Overview

The Hyundai WIA KF5/50 is a 50-taper vertical machining center on a mid-size frame. Hyundai WIA lists a BBT50 direct-drive spindle at 8,000 rpm, rated 22 / 11 kW (29.5 / 14.8 hp) and 353.2 / 143 N·m (260.5 / 105.5 ft-lbf), over travels of 1,050 × 560 × 510 mm (41.3 × 22 × 20.1 in). HSK-A100 is the optional spindle interface.

The point of the machine is torque in a modest envelope. The KF5700B II Series covers almost the same travels, 1,100 × 570 × 520 mm (43.3 × 22.4 × 20.5 in), with a BBT40 spindle listed at 15 / 11 kW (20.1 / 14.8 hp) and 286 / 143 N·m (211 / 105.5 ft-lbf). Against the KF5700B II Series, the KF5/50 brings the larger taper, 22 kW at the top of its rating and about 23% more torque at the top figure. That is what large face mills, big drills and long boring bars ask for.

The axes are not slow for a 50-taper machine. Rapids are 36 / 36 / 30 m/min (1,417 / 1,417 / 1,181 ipm) in X, Y and Z, with 42 / 42 / 36 m/min (1,654 / 1,654 / 1,417 ipm) as an option. The table measures 1,300 × 560 mm (51.2 × 22 in) and takes 1,000 kg (2,205 lb). It is longer than the X travel, so the ends of a full-length part sit outside the spindle's reach.

The ceiling is speed. 8,000 rpm is the only spindle speed listed, which holds back small cutters in aluminium, and Z travel of 510 mm (20.1 in) has to be shared between the part, the fixture and 50-taper tooling that tends to be long.

Strengths & Limitations

Strengths

BBT50 direct-drive spindle rated 353.2 / 143 N·m (260.5 / 105.5 ft-lbf) and 22 / 11 kW (29.5 / 14.8 hp)
HSK-A100 available as an optional spindle interface
Rapids of 36 / 36 / 30 m/min (1,417 / 1,417 / 1,181 ipm), with 42 / 42 / 36 m/min (1,654 / 1,654 / 1,417 ipm) optional
1,300 × 560 mm (51.2 × 22 in) table rated for 1,000 kg (2,205 lb)
About 23% more top torque than the 286 N·m (211 ft-lbf) BBT40 spindle of the KF5700B II Series

Limitations

8,000 rpm is the only spindle speed listed, which limits small-diameter tools
The faster 42 / 42 / 36 m/min (1,654 / 1,654 / 1,417 ipm) rapids are an option, not standard
Z travel of 510 mm (20.1 in) is shared between part height, fixture and long 50-taper tools
The table is longer than the 1,050 mm (41.3 in) X travel, so its full length cannot be machined in one setup

Best For

Heavy face milling and large-diameter drilling in steel and cast iron Boring with long bars that need a 50-taper connection Parts up to 1,000 kg (2,205 lb) within 1,050 × 560 mm (41.3 × 22 in) Shops standardised on BBT50 or HSK-A100 tooling

Frequently Asked Questions

01 What spindle does the KF5/50 have?

A BBT50 direct-drive spindle with a maximum of 8,000 rpm. Hyundai WIA lists power as 22 / 11 kW (29.5 / 14.8 hp) and torque as 353.2 / 143 N·m (260.5 / 105.5 ft-lbf). HSK-A100 is offered as an optional interface in place of BBT50.

02 How does the KF5/50 differ from the KF5700B II Series?

Mainly in the spindle. The KF5700B II Series uses a BBT40 spindle at 8,000 rpm (12,000 rpm optional) with 286 / 143 N·m (211 / 105.5 ft-lbf), and rapids of 30 / 30 / 24 m/min. The KF5/50 has a BBT50 spindle with 353.2 / 143 N·m (260.5 / 105.5 ft-lbf) and rapids of 36 / 36 / 30 m/min. Both carry 1,000 kg (2,205 lb) on the table.

03 How fast are the rapids on the KF5/50?

Standard rapid traverse is 36 m/min (1,417 ipm) in X and Y and 30 m/min (1,181 ipm) in Z. An option raises that to 42 m/min (1,654 ipm) in X and Y and 36 m/min (1,417 ipm) in Z, so check which set a quoted machine has.

04 What table size and load does the KF5/50 offer?

The table is 1,300 × 560 mm (51.2 × 22 in) with a maximum load of 1,000 kg (2,205 lb). Travels are 1,050 mm (41.3 in) in X, 560 mm (22 in) in Y and 510 mm (20.1 in) in Z, so the table overhangs the X travel at both ends.

05 Is the KF5/50 suitable for high-speed aluminium work?

It is not built around that. The listed spindle speed is 8,000 rpm with no faster option, so small cutters cannot reach high surface speeds. The machine's strengths are the BBT50 taper and 353.2 N·m (260.5 ft-lbf) of top torque, which favour heavy cuts with large tools.
