CNC machining

Crytur operates a top-class modern and versatile CNC workshop to machine precise mechanical and optical components for optoelectronic devices.

High variety of materials

Most common materials include
metal - steel, aluminium, titanium, tungsten, molybdenium, special alloys
plastic - PMMA, PA, PAI, PTFE
glass - quartz glass, glass-ceramics (zerodur, macor)
hard-to-machine materials - ceramic, crystals

 

Extemely high presision 

Standard tolerance ± 0.02 mm
Maximum precission tolerance down to ± 0.005 mm 
Circularity down to in specific cases

Controlled manufacturing conditions

Our most precise CNC machines operate in isolated workspace with controlled environment (temperature, humidity) to achieve the best available output.

Continuous dimensional inspection

The CNC workshop operates a 3D measurement laboratory for continuous a quick dimensional inspection.
