German machining centre manufacturer Roeders has introduced a new production centre, the RXU 2000, for manufacturing large components requiring a high degree of precision. The 3-axis machine is intended not only for 3D milling but also for jig, vertical or profile grinding. Availability in the UK and Ireland is through sole sales agent Hurco Europe, High Wycombe (www.hurco.co.uk)
The machine has been designed for high performance when cutting hardened materials and has a working volume of 2,000 x 1,800 x 800 mm. The Z-axis travel has been intentionally limited to ensure maximum accuracy. Both the Y and Z axes feature the machine builder's rigid, robust Quadroguide design, while the massive machine bed is very effective at damping vibrations. Maximum table load is five tonnes.
The combination of milling and grinding in a single set-up on the same platform is particularly well suited to mould and tool making and to producing high accuracy parts for machine building. Linear drives in all axes as well as an advanced temperature management system for the entire machine ensure the highest levels of precision, even during long machining runs. Dimensional accuracy to within 5 microns, and roundness of 1 to 2 microns depending on bore size, can be achieved throughout the machining envelope.
A 22,000 rpm, 101 Nm, HSK-A63 spindle is available for high metal removal rates. Alternatively, spindles up to 80,000 rpm may be supplied for different applications. On request, the machining centre can be configured as a double-spindle machine, for example with a high-precision air bearing spindle alongside the main spindle.
