Diamond turning – Wikipedia
Machinabillity turned surfaces have a high specular brightness and require no additional polishing or buffing, unlike other conventionally machined surfaces.
Cutting fluids in grinding, honing, super-finishing.
Free Online Course: Introduction to Machining and Machining Fluids from NPTEL | Class Central
Quality of surface finish and form accuracy is monitored throughout the manufacturing process using such equipment as contact and laser profilometerslaser interferometersoptical and electron microscopes. Optics Glass production Machining. International Journal of Abrasive Technology.
Introduction to Machining and Machining Fluids
The chuck itself is separated from the electric motor that spins it by another air suspension. Standoff distance, angle of impingement, contact angle, area of cooling, Solid lubricants. Sign up for free. Cutting fluids for machining advanced materials, high speed machining, hard machining.

Temperature control is crucial, because the surface must be accurate on distance scales shorter than the wavelength of light. Views Read Edit View history. Electron Beam and Laser Beam Machining. Your account has been activated.
Please help improve this article by adding citations to reliable sources. Diamond turning is most often used for making infrared optics, because at longer wavelengths optical performance is less sensitive to surface finish quality, and because many of the materials used are difficult to polish with traditional methods.
Methods of mounting of jobs npfel cutting tools in machine tools. Materials that are readily machinable include: The machined element is attached to an air chuck using negative air pressure and is usually centered manually using a micrometer. Don’t have an account?
