We specialise in the design and manufacture of surface roughness specimens of all types. Working together with major instrument manufacturers, national measurement laboratories and also as a partner in an EU-
We also provide a measurement and calibration service for surface roughness in our standards laboratory.
Our company was founded in 1941 and began manufacturing electrical tools and equipment, branching out into mechanical engineering during the 1950s with the manufacture of cast-
In the early 1960s we began to produce our first roughness comparison specimens. Initially these were individually machined and individually checked blocks of steel, but they gradually gave way to specimens electroformed in nickel, at lower cost and with much better quality control.
In the 1980s we introduced our first precision roughness standards to be used for calibrating and checking roughness measuring instruments; and since then our range of specimens has expanded steadily to become the world’s largest range of different surface specimens offered by a single manufacturer.
In order to improve our manufacturing processes so as to be able to produce surface specimens with very fine features, and with good accuracy, we have built a brand new factory on our site in Cheadle, set in beautiful countryside. This was occupied in March 2003.
During this period we have:
- developed new surface specimens as detailed in standards such as ISO 5436 and ISO 12179
- participated in a European Community-
funded research project to investigate the manufacture of roughness specimens with nanometer- scale features
- pioneered the use of surface-
hardening techniques to protect electroformed specimens against scratches
