Mazak INTEGREX i-500ST

The Mazak INTEGREX i-500ST is the INTEGREX i-500 with a second spindle and a lower turret, the configuration Mazak's model list calls Second Spindle, Lower Turret. It turns Ø28 in (711 mm) by 62 in (1,575 mm) between two 10 in chucks, with a 12,000 rpm milling spindle overhead and the turret working from beneath.

Start with what the turret reaches, because it does not cover the whole machine. Its maximum machining diameter is Ø19 in (483 mm), where the machine as a whole turns Ø28 in (711 mm). Its Z2 travel is 54 in (1,372 mm), where the milling spindle has 65 in (1,651 mm) of Z. X2 travel is 11 in (279 mm), and both turret axes rapid at 1,575 ipm (40 m/min) while the milling spindle's axes run at 1,969 ipm (50 m/min). A job should be laid out so that the operations given to the turret fall inside that smaller window, and the outer diameters and the far end of the stroke are left to the milling spindle.

The table lists a tool capacity of 9 tools, positioned with the lower turret figures. It gives no magazine count for the milling spindle on this version, though it does give the magazine tool limits: Ø4 in (102 mm), Ø6 in (152 mm) with adjacent pockets empty, 20 in (508 mm) long and 26 lb (12 kg). Confirm the magazine size with Mazak. The INTEGREX i-500S, which shares these travels, lists 36 tools.

Both turning spindles are rated 22 kW (30 HP) continuous and 30 kW (40 HP) at 40% ED at up to 4,000 rpm. At 49,162 lb (22,300 kg) this is the heaviest of the three i-500 versions: the INTEGREX i-500S weighs 48,280 lb (21,899 kg) and the INTEGREX i-500 weighs 46,958 lb (21,300 kg). The footprint is 220 in (5,588 mm) × 134 in (3,404 mm).
