Hyundai WIA F960B

The Hyundai WIA F960B is a long-table, 50-taper machining center: 2,450 mm (96.5 in) of X travel over a 2700 × 950 mm (106.3 × 37.4 in) table rated for 4,500 kg (9,921 lb). Y travel is 960 mm (37.8 in) and Z is 850 mm (33.5 in). The spindle is a gear-driven BBT50 unit with a maximum of 8,000 rpm, listed at 776 / 657 N·m (572.4 / 484.6 ft-lbf) and 22 / 18.5 kW (29.5 / 24.8 hp).

Table and travel are best read together. The 960 mm of Y travel covers the 950 mm table width, so the spindle reaches the full depth of the table. X travel is shorter than the 2700 mm table length, which leaves the ends of the table as clamping room and not cutting room. A part that uses the whole 2,450 mm (96.5 in) can still be strapped down outside the cut.

The gear box explains the torque. 776 N·m (572.4 ft-lbf) from a 22 kW (29.5 hp) motor is a low-speed, high-torque arrangement for large face mills, big drills and boring bars in steel and cast iron, and 8,000 rpm is the ceiling that comes with it. Rapids are 16 m/min (630 ipm) on X and Y and 20 m/min (787 ipm) on Z. Those are unhurried rates, and on a machine that spends its time in long cuts on heavy parts they cost little.

The magazine holds 20 tools. That is the figure to check hardest against the intended work: the KH1000, for comparison, lists 60 tools. A plate or mould base with many hole sizes can fill 20 pockets, and after that tools are changed by hand. WIA's table for the F960B has no pallet row, so parts are loaded on the one table.
