single point diamond crushing glass

  • Single point diamond crushing of glass (Conference) OSTI.GOV

    Single point diamond crushing of glass was originally developed by Dr. R.E. Reason of Taylor and Hobson in England 34 years ago as a means of shaping glass aspheres prior to polishing. It has recently been tried at LLNL. A surface finish of 50 microinches peak-to-valley with occasional deeper pits has been achieved on Zerodur and BK-7 glass.
