RB-M High-Speed Multi-Center

RB-M High-Speed Multi-Center

The RB-series, among the industry’s best-selling models with over 4,000 RBs in the field, leads machinery industry.
The machine is equipped with traditional basic construction and new features, and has now evolved into the next-generation high-speed five-face machining center.

  • Continuous machining on work with steps is possible thanks to full-stroke of Z plus Wunder NC control.
  • High-precise machining that takes advantage of the features of round column.
  • Capability of side-face machining improves dramatically thanks to the quill automatic mounting angular attachment with 5,000 min-1 of maximum permissible spindle speed and 22 kW of maximum output.
  • New five-face machining software that realizes “easy-to-use five-face machining center” is attached. The machine is equipped with functions such as automated coordinate conversion, completely automated splitting of Z-W axes, and full-measure interactive machining pattern software.

Full-stroke with four-axis controlled Full-stroke with four-axis controlled
Highly-efficient continuous machining from thin-piece to boxed-piece is possible thanks to full-stroke with four-axis controlled. In addition, high-rigid machining that keeps the quill extension minimum is available because machining with moving W-axis to optimum position is possible.
Powerful angular attachment Powerful angular attachment
Thanks to newly developed angular attachment and compact strong side-surface cutting that displays 22kW of full-power, dramatic improvement of efficiency is possible.
Besides standard indexing at 90°, indexing at 5°is optionally available, and it helps machine various kinds of workpieces.
Vertical and horizontal Automatic Tool Changer Vertical and horizontal Automatic Tool Changer
The machine is equipped with an automatic tool changer (ATC) that has 40-tool storage capacity. It can be used in both vertical spindle and attachment, and doesn’t bother tool management.
ATC with 60, 80, 100, and 120-tool storage capacity is optionally available and it enables high automatic operations.
Attachment Attachment
The machine is equipped with an automatic attachment changer (AAC) with automatic open-close type (for one attachment). Vertical and horizontal continuous machining by automatic operations is possible.
In addition, 30°inclined attachment, 90°universal attachment, extension attachment and small-sized special angular attachment are selectable according to the purposes.
Strong cutting by vertical spindle
Many skills such as high-rigid machine structure and large diameter
quill realize highly-efficient machining, and enable strong cutting.
