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.

For Idex Health and Science, manufacturing glass components was time-consuming on a VMC. Switching to an HMC with a Cluster Tower vise with DoveLock jaws from Kurt Manufacturing enabled more stable, lights-out machining.
