Split nut saves time

Product News Tuesday, June 14, 2011: ABSSAC LIMITED

Another satisfied customer required a more sophisticated nut design for use within a hot glue dispensing machine. By supplying a specifically designed bronze nut to match a 20mm diameter by 4mm lead trapezoidal power screw, the bronze nut was then meticulously separated into two halves. When the two halves of the nut were brought together via a precision slide arrangement, the nut functioned in complete confidence as if it were whole. The driven screw enabled the nut to traverse its length, as the hot glue was accurately dispensed but then the nut separated at the end point and returned quickly to the start position. This meant that the screw required only one direction of travel and reduced the cycle time for the glue head to return to the start position.

To date many bespoke nut designs have been supplied, including optical mounts, cams, external threads, mounting holes, pulley grooves, tangs and linear guides to name a few. Lead screw sizes range from 1mm diameter up to 100mm with a wide range of both metric and imperial leads per diameter. Nuts can be manufactured in just about any machineable material including Bronze, steels and advanced plastics such as Delrin, PTFE or Turcite.
