In many if not all cases, this kind of precision level ... and glazing problems, enabling uninterrupted grinding and a mirror surface finish on materials that are difficult to machine with finegrained wheels (numbers 6000 to 8000).
Making A Mirror Grinding Tool By Allen Malsburry The average person would never think, "I can make my own telpe." Most amateur astronomers believe, "I can buy a better telpe than I can build." Neither is actually correct. For many decades now, amateur astronomers have been building their own telpes. ...
Lens Mirror Making • Best lenses and mirrors are both made by grinding the surface • Start with a mirror or lens blank • For mirrors only surface needs to be good • Typical mirror want pyrex (eg BK7) • Then need a tool blank – poorer glass softer glass • Place mirror on top tool • Now add grinding compound (grit) between ...
Study of Machine Tools – Grinding Machines Page 3 Grinding machine operations The process of grinding is the operation of removing excess material from metal parts by a grinding wheel made of hard abrasives. The following operations are generally performed in a grinding machine.
to be employed. Flexibility in speed control allows the instrument to be used as a grinding machine, high quality lapping machine, or polishing machine. During grinding high speeds are required, whereas lapping and polishing applications are generally completed at low speeds. The Model 920 also incorporates workstations, which allow for the use of

Sep 29, 2010· Mirror Grinding Machine posted in ATM, Optics and DIY Forum: I have some interest in building a grinding machine for possible up to an 18 mirror, but something that will also do a 6 or 8 mirror. I have plans for the Mir O Matic but would like to do something a bit more modern. I have some ideas about using a AC drive and a large aluminum disk for the turntable .
Grinding Wheels Use of ultrafine diamond abrasive achieves high die strength while maintaining gettering performance, and offers new solutions for wafer thinning. UltraPoligrind employs an ultrafine diamond abrasive to create higher die strength and enable grinding with even less damage than Poligrind.
Grinding of toroidal and cylindrical surfaces made of Si and SiC was carried out by using diamond grinding wheels and an inexpensive computerized, numerically controlled (CNC) machining center.[14,15] Mirrors were successfully obtained by automatic grinding operations with good shape accuracy, mirror surface finish, and low roughness heights.
Oct 03, 2006· Thanks for the video Jim. I had no idea that these machines ran at those speeds. When I built my machine, I didn''t have a computer or any books on building grinding machines so I built one that mimics the stroke a person would do. For instance, my turntable rotates at just one RPM and the stroke eccentric turns at 36 RPM.
Jan 01, 2012· Aluminum mirrors. Manufacture using polishing machine posted in ATM, Optics and DIY Forum: Hello everyone. Due to questions I have received about polishing the aluminum mirror using polishing machine, I have prepared a brief guidebook. The guidelines are essentially practical as I consider that the manufacturer has experience in optics and the use of mirror polishing machines.:
I designed and built a grinding machine for mirrors up to 42 inches [] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work. The machine can also work smaller mirrors if the drip pan is moved to the fast shaft on the side of the machine.
