Lathe chuck overview Mounting and machine spindle noses Lathe chucks with cylindrical centring mount to DIN 6350 and DIN 6351. These lathe chucks are screwed to the DIN 800 spindle nose using a flange (see No. 31 7000). They are secured using hexagon socket-head screws. The lathe chucks are also applicable on spindle noses with a short taper, using a short taper flange. However, it is preferable to use lathe chucks with an integral short taper because of the lower overhang. T Spindle noses DIN 800 Secured from the rear.
