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 ...

Dec 15, 2002· In rotary point crush dressing, the surface speed of the grinding wheel and the surface speed of the dressing disk are synchronized. This creates virtually a single point of contact between the diamond grinding wheel and the dressing disk. Because there is no slippage between the diamonds, forces are lower and a thinner dressing disk can be used.

May 28, 2017· For customers who are new to SPDT, I think there is still confusion on what materials can be used. Customers ask about diamond turning glass and 99.9% of the time we cannot, but we are working with a new Laser Assisted Diamond Turning accessory that is improving our ability to successfully diamond turn silicon and certain glass types.
Single Point Diamond Crushing Glass. SinglePoint Diamond Dressers26 . IDTD01 SinglePoint Diamond Dressers FEATURES U Manufactured by sintering a selected diamond crystal with a metal matrix into a steel shank. U The point of the set diamond is concentric with the shank.
Faster production of large optical mirrors may result from combining single-point diamond crushing of the glass with polishing using a small-area tool to smooth the surface and remove the damaged layer.
Single Point Diamond Turning (SPDT) is a manufacturing process used to quickly produce low to moderate volumes of highly accurate plastic optics, usually to support R&D or prototyping efforts. The machine that does the single point diamond turning is a precision CNC lathe.
Faster production of large optical mirrors may result from combining single-point diamond crushing of the glass with polishing using a small area tool to smooth the surface and remove the damaged layer. Diamond crushing allows a surface contour accurate to 0.5 microns to be generated, and the small area computer-controlled polishing tool allows ...
A machine tool of very high stiffness has been constructed and used for single-point diamond grooving of blanks of soda-lime glass and optical glassy quartz. Results show that below a critical depth of cut predicted in order of magnitude by a fracture mechanics analysis, material is removed by the action of plastic flow, leaving crack-free surfaces.
The feasibility of single point diamond turning optical quality glass surfaces has been experimentally studied. The main objective of the research is to study the ductile removal process of glass and identify the important parameters.

In this work, soda-cal silicate glass samples were machined in an ultraprecision machine tool. Single point diamond turning tests with submicrometer cutting conditions (depth of cut and feed rate) were carried out. The interrupted cutting test is performed to analyze the cutting tool profile left on the machining surface.
Diamond turning is turning with diamond as the cutting tool.It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits.The term single-point diamond turning (SPDT) is sometimes applied, although as with other lathe work, the "single-point" label is ...
