We have one of the leading diamond turning facilities in Europe, housing
4 CNC single point diamond turning lathes and 1 fly-cutter. With lathes of different sizes
and capabilities, we have great flexibility in assigning different
workloads to different tools, ensuring the shortest delivery timescales.
Our diamond turning facility can routinely produce complex
non-spherical surfaces on a comprehensive range of optical materials and
metal alloys. Transmissive optics can be machined as aspheric,
diffractive, hybrid and Fresnel lenses in Germanium, Zinc Sulphide and
Selenide, Silicon and acrylic and other plastics. Reflective optics and
mould tools can be machined in aluminium alloys, OFHC copper and copper
alloys, brass, bronze and electroless nickel.
The most recent addition to the diamond turning facility is a
Nanoform 700 single point diamond turning lathe from Precitech Inc.
Capable of producing high quality optical form and finish on a wide range
of non-ferrous metals, crystals and polymers, the Nanoform 700 can accommodate
optical components up to 700mm diameter.
