Miniature Perfection

Abssac is well known for its quality power screws ranging from about 16mm up to 200mm in diameter, but an often little known side of the company is its capability to supply precision miniature cold rolled formed lead screws and nuts.

When dealing with screw diameters from 2mm up to 6mm the key is in the manufacturing technique to ensure thread integrity and lead accuracy. Applications are numerous and Abssac has found its products being supplied to different markets such as medical, defence and robotics around the world. In each case, whether it is a single start or multi helix thread form, linear run out and concentricity of the thread is maintained to a precision classification. Miniature lead screws have been supplied in both Steel and Stainless Steel and on some occasions in plastics.

Matching the screw to a suitable nut is also taken care of by the knowledgeable application engineers at Abssac who ensure performance orientated nut designs at competitive costs. Miniature lead screw applications require smooth operation and low frictional drag due to physically smaller drives with torque limitations. Ensuring the fit between the nut and screw threads is of paramount importance as any small errors in these areas can lead to torque spikes during operation. Then finally you look at how to attach the nut to the application. Can we add tangs, levers, external threads etc. to make the part do more.

The next time you have a miniature application that requires the translation of rotary input to linear output then perhaps give Abssac a call.
