Why choose Agate

Specialists in precision machining

Founded in 1946, we have over 70 years’ experience in the precision machining of ultra-hard materials making us one of the leaders in our industry. Our customer base is diverse and worldwide.

Vast experience of ultra-hard materials

We predominantly machine and supply parts in alumina, sapphire, silicon carbide and quartz but also a whole range of other materials.  Many of the standard size materials are held in stock allowing us to offer faster lead times.

Multiple machining capabilities

Our substantial production facilities house large capacity surface, cylindrical and centreless grinders as well as a CNC department together with drilling, honing and lapping/polishing machines.  We invariably machine to very complicated designs and tight tolerances.

Prototypes or larger production volumes

We are the company of choice for universities/R&D facilities who require low volume prototypes. However, our manufacturing facility is equally at ease with larger production volumes.

Friendly approachable company

We are happy to share our experience with our customers and advice is freely given to allow our customers to achieve their objectives feasibly and as economically as possible.
