Initial stages of machining are carried out using a series of CNC lathes of increasing accuracy. Each diamond-turned optical element is manufactured on an individual basis with extensive manual labor. Temperature control is crucial, because the surface must be accurate on distance scales shorter than the wavelength of light.

Introduction to Machining and Machining Fluids

Cutting fluids in grinding, honing, super-finishing. Didn’t receive the activation email? Optical elements produced by the means of diamond turning are used in optical assemblies in telescopesvideo projectorsmissile guidance systems, lasers, scientific research instruments, and numerous other systems and devices.

Hybrid processes such as laser-assisted machining have emerged in this industry recently. The cutting tool is moved with sub-micron precision by a combination of electric motors and piezoelectric actuators.

Never miss a course! Finishing processes honing, laping burnishing and deburring. Despite all the automation involved in the diamond turning process, the human operator still plays the main role in achieving the final result.
