The machine orbits from .020" to .200" (.51 mm to 5 mm). As the machine vibrates in a circular motion within a bath of oil, the impregnated pattern forms the graphite electrode. See Figure 11:8. The abrading tool produces a very fine finish on the electrode. Multiple electrodes can be produced from the same pattern without any secondary ...
Machine Shop Services Assembly Services Thin Film Coating Services Engineering Services. Optical Polishing. Optical polishing is the precipice of optical fabrication. It is the department that without, one wouldn''t have finished optics. Our polishing department is truly one of the most unique and critical departments within Precision Optical.
gear are all we need to construct this grinding machine. The wooden platform on the turntable is faced true, to permit a wellcentered reflecting surface to be obtained. The main task of producing a perfect spherical concave surface should be solved by the use of a grinding tool swinging over the mirror .
A polishing machine smooths the surfaces of a product. The process can use abrasion or work hardening methods to furnish a surface meeting aesthetic or technical requirements. Applications. These machines are used in gold and silver smithing, iron working, foundries and woodworking, as well as in optical and medical domains. Technologies
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.

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 and have made a parts list .
Rough Grinding. Unless the mirror comes pregenerated, the initial curve will have to be ground into the mirror. A ring tool of half the diameter of the mirror used on top of the mirror''s flat face with the coarsest grit will rapidly grind a spherical curve into the mirror. Grinding a 6 inch [15cm] mirror to F/ using a ring tool. Mirror ...

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.
Abstract. This exercise is not intended to make a perfect piece of optics, but just to show the principle of the methods used in practice and to convince our students that amateur telpe making is surprisingly simple and accessible.
MirrorOMatic grinding machine. When I decided in 2009 after a tenyear break to get into mirror making again, it quickly became clear to me that I would need to construct machine, as hand grinding big mirrors is not something very beneficial for the hands of a musician.
grinding direction and repeat steps 3 thorugh 6. 8. When the 180 grit stage is complete, you''re ready to move on to the medium/fine grinding station. Medium and Fine Grinding Medium and Fine Grinding of metallurgical samples are closely allied with the Coarse Grinding which precedes them.
Dec 16, 2014· Gordon started with a 2" thick telpe mirror that weighed about 70 pounds. By thinning the blank, he''s lightened the mirror by about 20 pounds! This video explains how he ground off the excess ...

Jan 22, 2010· Additionally, several types of grinding machines may be needed to perform the operations able to be performed on a single turning center, further opening the possibilities for equipment cost savings. As mentioned above, a turning center can complete ID turning, OD turning, taper turning, and grooving in a single chucking.
After fine grinding is complete, the mirror must be polished. It is during polishing that you "figure" the mirror by using a different polishing stroke to change the mirror''s spherical polished shape into a parabolic polished shape . See a related tutorial nearby
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 precise Lapping and Polishing Fixtures. Each workstation has it''s own speed control, allowing the user to precisely
Grinding Machine for Large Telpe Mirrors 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.
Fleece sanding pad and flap disc for the Inox angle grinders, sanding belts in different versions and grits for the tube belt sanders and band files, grinding wheels and rollers for the burnishing machine and many other accessories for processing stainless steel get the best out of the Inox machines and ensure shiny results when working.
Grinding Motion • Move mirror back and forth over tool grinding compound • After number of strokes rotate mirror, tool in opposite direction • Change position of stroke alternatively • Eventually move fully around the mirror • Grit removes material from both • But tool edges wear down, while mirror center carved out
