Generating the curve on a mirror blank is a tedious process when done manually or a messy (and dangerous) affair when done with machines. After reading an article by Ed Jones about using diamond pellets for that task, I wanted to try the idea on the grinding machine.
#0183;#32;Page 1 of 2 Making my own fixed post mirror grinding/polishing machine posted in ATM, Optics and DIY Forum: Hey guys. Im thinking of making my own fixed post mirror grinding/polishing and curve generating machine. Ive got loads of questions regarding the design so Ill just start firing away Do I need an eccentric moving tool to be able to polish a mirror spherical?

Luckily the mirror needed but a bit more parabolizing which was largely added during the subsequent work session. The mirror began figuring with a radius of curvature of inches [3348cm], so the total shrinkage was inches [13mm]. The Bartels'' rule of smoothness first and always. No matter what goes on, strive for a smooth curve on the
This is why you don''t want to make mirrors to be worked on machines too thin. For 16quot; to 18quot; mirrors, quot; thick is the thinness I would recommend. There are several ways to support the grinding and polishing machine turntable, but first make sure the turntable itself is rigid. It must not bend.
#0183;#32;A high efficiency precision truing experiment for arcshaped diamond grinding wheel is carried out on ultraprecision grinder NAS520XCNC, the experimental setup is shown in Fig. parameters of the dressing experiments are shown in Table order to improve the truing efficiency, a 180# GC wheel was chosen to dress the120# diamond grinding wheel during the dressing experiment.
#0183;#32;The Diamond curve generating machine in this video is grinding a 16'' mirror blank. The purpose of this machine is to generate a curve into the mirror using homemade grinding tools, a diamond saw

For generating spherical / plane surface of big diameter optical element. Features: machine adopts highspeed rotating diamond wheel grinding and using a servo motors to make vertical feed accurately. The accurate process is automatic controlled by numerical control system.
#0183;#32;The mirror grinding of curve surface may be fabricated by the ELID grinding, but the electrolytic dressing system of superfine diamond wheel was complex and inefficient. It has been known that the ductilemode mirror grinding depends on the grain cutting depth less than the critical cutting depth for the transfer from brittlemode removal to ductilemode removal [16] .
Fixedpost machine grinding is where the mirror is on a turntable rotating around 20 PRM [speeds vary], and a 75% tool is on top. They are already curvegenerated. The tool is hanging over the mirror by 1/6 the diameter of the tool, or about 1/8 diameter of the mirror, and is fixed in this position.

The curve is ground into the mirror face using a grinding tool. The curve is pregenerated for you. The curve is created by slumping the blank in a kiln over a mold. Here are 42 inch [107cm] and 30 inch [762cm] mirrors slumped and annealed to ready for fine grinding. The first method is by far the most popular. Grinding the curve into the
