Mitsui Seiki’s HU100 series is a range of configurable machining centres aimed at a variety of heavier applications in manufacturing industries.

Mitsui Seiki will introduce these machines to North America at IMTS 2010.

Configurable machines are based on a set of standard modular components that can be arranged to suit specific customers’ needs, easily and affordably.

Mitsui Seiki’s approach to providing customers with the ideal technical solution has just become easier.

For example, users can choose axis travels from 1300 to 2500mm; four, five or six axes of continuous motion; and a choice of a rotary table, trunnion table, or table on table.

There’s also a variety of spindle choices, including fixed spindles from 6000rev/min (50HP, 2000ft.lb torque) for heavy milling up to 25,000rev/min for high-speed applications.

Tilt or swivel-spindle choices are available from 6000rev/min (800ft.lb torque) for heavy milling up to 12,000rev/min for high-speed machining.

Mitsui Seiki also offers quill-type spindles for precision boring with shorter tools.

Mitsui Seiki applications engineers help customers to select the optimum component choices to meet their needs and objectives, now and in the future.

The HU100 series is ideal for larger aerospace and power-generation parts with a work-zone capacity of up to 2500mm diameter x 2000mm height.

The machines accommodate weights from 4,400lb (2,000kg) to 17,500lb (8,000kg).

These machines can be equipped with simple pallet changers to fully integrated FMS systems for work and raw-material handling.

Likewise, tool-handling systems range from on-board magazines to central systems for more than 2,500 tools.

The HU100 line is already one of Mitsui Seiki’s most popular products and has been sold to industries as diverse as aerospace, refrigeration compressor, mould and die, heavy equipment and energy.

All of these industries have fundamental common requirements: machine rigidity/stiffness and high accuracy.

As with all Mitsui Seiki’s machine tools, high accuracy and ultra rigidity come from the builder’s attention to the basic structure, 3D FEM design, hand scraping of all castings for geometry and frequency tuning, plus hardened and ground steel box ways.
