The Mazak INTEGREX i-450H ST multi-tasking center showed its part-processing agility at IMTS 2022. With the power of a full CNC turning center and the versatility of a full-function machining center, the INTEGREX i-450H ST features a second turning spindle (S) for DONE IN ONE® machining, along with a milling spindle and lower turret (T) with optional rotary tool capabilities. The configuration minimizes fixturing, part handling, and non-cut time to boost productivity.
The main spindle incorporates a 12-inch chuck and produces a maximum speed of 3,300 RPM from a 50 HP, 37KW 40 percent ED spindle motor. Maximum machining diameter is 26.380 inches (670 mm), and the main spindle’s 4.4-inch (112 mm) diameter bore accommodates bar stock up to 4 inches (101 mm) in diameter. The second turning spindle further expands processing flexibility with a 10-inch chuck, 35 HP (26 kW), and 4,000 rpm cutting, and the milling spindle provides B-axis travel of 240° with cutting speeds up to 12,000 RPM. An automatic tool changer supplies the milling spindle from a 38, 74, or 112-tool magazine. For fast part changeovers, the INTEGREX i-450H ST features an optional auto chuck changer with ten-jaw stockers located on each spindle and operated via program commands.
The machine’s parallel-type twelve-tool lower turret offers a rotary tool option with 10,000 RPM and 10 HP (7.5KW). This enables manufacturers to employ balance cutting with the milling spindle and lower turret, or carry out simultaneous machining with two tools. The turret accommodates 1-inch (25 mm) turning tools or 1.5-inch (40 mm)-diameter boring bars.
The machine enclosure, tool magazine and optional auto jaw changer are designed to accommodate a comprehensive range of automation technologies, including gantry loaders, bar feeders, and articulating robots. The machine’s MAZATROL SmoothAi CNC enables the INTEGREX i-450H ST to carry out standard specialized operations such as crankshaft inclined drilling and gear skiving.
