Diamond machining is a process in which a single point diamond is used as a cutting tool, in a fly cut or turning operation. The process takes place with equipment using highly accurate gas bearings in the linear and radial axis. Diamond machining would be an efficient alternative method of producing aluminum mirrors over optical polishing.

Diamond Machining Offers These Advantages:

• The cutting forces are very small because of single point contact as well as a small, accurately controlled depth of cut. Very low stress is introduced into the work piece.

• Optical quality components including mirrors are produced with typical surface roughness less than 100 angstroms (0.3 micro inch).

• Sizes and dimensions can be held to much closer tolerance than conventional machining or grinding processes because of the accuracy of the air bearing slides and spindle.

• Very good quality and excellent repeatability of surface finish on most soft nonferrous materials. Aluminum alloys from 2024 to 7075, copper, brass, PVC, acrylics.
