    The WM 250-8000 whirling machine from Burgsmüller claims maximum precision over a machining length of 6,250 mm.

    According to the German exhibitors, their new whirling machine provides customers with substantially enhanced precision during the hard whirling of ball screw spindles over the entire machining length with a maximum plus/minus 7 micrometers pitch diameter tolerance. A third prism-jaw self-centering steady rest with user-selectable position serves to fix and center the free end of the bar stock, while the spindle axis is kept free so that the bars can be pushed through it, as the manufacturers describe the functioning the machine. The 90° chip conveyor removes the chips from the spindle axis and additionally facilitates the through-loading of material in order to whirl spindles of any length using the repositioning process. Integrated measuring systems monitor the fitting in the already whirled thread during repositioning. In addition, as the manufacturers also point out, the whirling attachments can be equipped with a controlled A-axis (inclination adjustment) so that the angle of inclination of the whirling attachment follows the changing pitch angle during the machining process.
