The new HU63EX horizontal machining center from Mitsui Seiki USA, Inc. is engineered to boost metalworking productivity through a combination of precision, power, and torque. The 17,000kg (37,400lb) machine has a footprint of 2,900mm (116") x 3,180mm (127"), with X, Y and Z axes travels of 900mm, 800mm and 800mm (36", 32" and 32") respectively.
The machine’s structure maximizes rigidity and accuracy. The bed is a single casting supported at three points, which minimizes the effect of foundation fluctuations on accuracy. A thickened structure and specifically-developed rib configuration generate high rigidity. The mating surface of each axis box way, as well as other important areas such as rotary axis mounting, ball screw mounting points and spindle attachment surfaces are carefully hand-scraped, establishing extremely precise geometric characteristics such as parallelism, squareness, and straightness. This ensures consistent accuracy over an extended period of time. Air cavities between the ways and the column mating surfaces are charged with low-pressure air, reducing the load on the way surface and enabling smooth movement without compromising rigidity. Ball screws located at the center of each guide way also assure stable movement.
Mitsui Seiki says the machine offers X, Y and Z axis positioning and repeatability accuracy of +/- 0.001mm (+/- 0.00004" or one micron), and B axis (rotating the 630mm [25.2"]-sq pallet) accuracy of +/- 2 sec with repeatability +/- 1 second.
The focus on accuracy and rigidity produces repeatable precision performance. According to Mitsui Seiki, in turn-boring operations on 10 consecutive workpieces the HU63EX achieves concentricity within three microns.
In addition to precision, the HU63EX offers substantial power and torque. The machine’s standard 50-taper, 6,000 rpm spindle offers 18.5/15kw (30 min/continuous, 24.7/20hp) power with 601nm (443 ft-lb) torque, delivered through a two-step gearbox. Optional spindles include a 6,000 rpm, 26kw/22kw (34.8/29.4 hp) unit with 1,081nm (797 ft-lb) torque and a three-step gearbox, and a 12,000 rpm, 30kw/25kw (40/33.5 hp) version with 420 nm (309 ft-lb) torque driven by an integral, built-in motor. |
| Bu firma hakkında: |
In 1928, the company manufactured measuring instruments, including block gauges and micrometers. Mitsui Seiki's quest for "precision" had begun.
In 1935, the company developed our first medium sized ?4?Jig Boring machine to Japan delight. For many years the country wanted their own jig boring technology rather than importing it. They referred to it as Japan first other?machine because it was primarily used by other machine tool builders to make their critical precision components. It helped spark a fledgling machine tool industry in Japan. Since then, jig boring machines have become synonymous with the label other machines?worldwide.
Currently, Mitsui Seiki offers a lineup of machines extending from jig boring machines, jig grinders, horizontal and vertical machining centers, to 5-axis machining centers and screw grinders that support the world leading industries. |
