  • Predicting residual properties of ball screw raceway in

    The residual properties of the ball screw raceway after whirling milling are the critical factors affecting the performance of the workpiece. Comprehensive research has been conducted to investigate the residual properties (including the residual stress and full-width half-maximum (FWHM)) of the ball screw raceway in dry machining.

  • Lead screw vs. ball screw

    I have a Clausing 8520 milling machine now - currently taken apart for cleaning and restoration - and I was giving some thought to seeing about maybe trying to add CNC to it at some point. Anyway, in doing a little preliminary research, it seems that ball screws work well for stepper motors, but maybe not so well for manual cranking.

    Ball screw in CNC milling machines and heavy industrial machinery. There are two types of spindles: lead screws and ball screws. The lead screw has a much simpler design, comprising a screw and a nut, so that the rotary motion of the screw is converted into the linear motion of the nut. Due to the continuous sliding contact between the screw

  • What is Ball Screw Accuracy and Why is it Important? | CNC

    Ball screws are used because they allow closer tolerances than standard types of screw assemblies and with lower friction due to the use of ball bearings. But they still need to be correctly designed and engineered in order to ensure acceptable levels of accuracy when used in a CNC mill. While backlash (sometimes called “slop”) is typically
