Quality in everything we do

Meeting the demands of the customer

William Hughes sends out millions of parts a year and they all have to be right, to various degrees of accuracy, depending on the application. Aerospace work requires very small tolerances, spring lengths must be right to within a few microns. Automotive work is less demanding, but still around 1mm per 100mm typically. To be able to measure these levels of accuracy, checks need to be performed throughout the manufacturing process in many different ways.

Wireforms & Assemblies

Wireforms can be checked in state of the art gauges that are designed and manufactured in house. For more accurate measurement, we would use a CMM (co-ordinate measuring machine) available in both our  factories.  The largest of the two machines is capable of measuring parts up to 1500 x 1000 x 800mm in size and is motorized for  accurate measurement and repeatability.  In the UK we have, in addition to contact CMM probe technology, a system for laser sensing contactless measurement which allows for a complete part to CAD comparison in under 5 minutes.

 

Torsion & Compression Springs

Checking springs needs a wide range of equipment to be carried out correctly. This includes:

  • Imaging tools, from a basic 10:1 shadow projector to CNC vision systems
  • Load testers, supplied by the Institute of Spring Technology (IST) and extremely accurate
  • Torque testers, CNC or manual.

There are even facilities here for testing and certifying the tensile strength of wire, to make the manufacturing process as accurate as possible.
