Measurement and Control Device of Preloaded Ball Screw Drive
The deviation often appears in the feeding device of machine because of the screw spindle geometry torsional moment and the wear. The automatic compensation of the changes was proposed by means of a ball screw pretightening device by using adjustable force measurement and control. The detail design and simulation were conducted for the specific device. A case study was presented for the CNC lathes application. Testing results have shown that the device can be easily operated with an acceptable precision for positioning.
