Makino’s T1 five-axis horizontal machining center enables high-efficiency machining for a range of large workpiece applications such as those required by the industrial, energy and aerospace industries. The HMC features an A/B-axis configuration that eliminates the need to tilt the workpiece by shifting A-axis motion to the spindle side, ensuring accuracy regardless of rotary axis position, the company says. The +45- to -110-degree A-axis tilting spindle coupled with a deep-chest column design enables a -90-degree spindle centerline positioning to 550 mm (21.6") beyond pallet center. The spindle tilting A-axis offers 6,300 Nm of continuous torque (20,000 Nm peak), and enhances spindle and workpiece accessibility with a 400-mm (15.7") pivot distance. The B-axis rotary table offers a 360-degree rotational speed of 3,600 degrees per minute, supported by 10,000 Nm of continuous torque (29,000 Nm peak).
The X-, Y- and Z-axis travels measure 1,500 × 1,300 × 2,000 mm (59.1" × 51.2" × 78.7"). The 1,000-mm (39.3") pallets accommodate workpieces ranging to 1,500 mm (59.1") in diameter by 1,500 mm (59.1") tall. Maximum pallet payload is 3,000 kg (6,600 lbs). The 12,000-rpm direct-drive spindle with HSK-A100 spindle interface offers 1,000 Nm (737 foot-pounds) of torque available from 20 to 1,000 rpm. Continuous power of 56 kW (75 hp) is maintained from 1,000 rpm to the maximum 12,000-rpm level. The machine is equipped with a high-pressure, high-volume through-spindle coolant system delivering up to 1,000 psi at 26 gpm. Twin coolant tanks each store 264 gallons of water-soluble coolant. Twin internal hinge conveyors and a dual-layer lift-up chip conveyor remove chips.
The machine is equipped with a 60-position automatic toolchanger and an automatic pallet changer. A 137-position toolchanger is available as an option, and the HMC can also be integrated with the Makino Machining Complex (MMC2) automatic pallet transfer and storage system.
