Ball Screw Enhancements

Kugel Motion have recently manufactured enhanced ball screws for a well known brand of hand tools, who have brought manufacturing back to the UK. Kugel Motion was approached by the company who were having problems with the life and reliability of ball screw assemblies in the grinding section of the workshop. Our experienced engineers used the sample as the design envelope, and designed a pitch-shift preloaded single nut arrangement in place of the inadequete double nut arrangement. The team at Kugel Motion also designed the ball transfer system to be as robust as possible for an extremely smooth run. The wipers were re-enforced and designed to provided a very effective wiping action on the shaft to reduce dirt ingress and maximise the life of the assembly. The entire process from raw material through to finished precision ground product was manufactured in house at the Kugel Motion facility. Ball nut turning, 4-axis transfer port milling, transfer liner manufacture, plain grinding and internal thread grinding were all performed in-house with Kugel Motion's precision thread grinding equipment. -- Kugel Motion is the only precision ground ball screw manufacturer in the UK offering bespoke, one-off and volume manufacturing for the Aerospace, Machine Tool and Automotive industries in both metric and imperial diameters and pitches. --
