gear are all we need to construct this grinding machine. The wooden platform on the turntable is faced true, to permit a well-centered 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 .
Rough Grinding The first milestone is putting a curve into the mirror face. The curve's depth dictates the mirror's focal length. The curve should be spherical. Creating the curve can be done by several methods: The curve is ground into the mirror face using a grinding tool. The curve is pre-generated for you.
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 Machine for Large Telpe Mirrors I designed and built a grinding machine for mirrors up to 42 inches [1.1m] in diameter. By slipping on and off a couple of belts, the machine can quickly be reconfigured for spinning work or for stroking work.

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.
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
Rough Grinding. Unless the mirror comes pre-generated, 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/2.8 using a ring tool. Mirror ...

Jan 22, 2013· Grinding with diamond abrasives is done by grinding the surface of the stone with various grits of industrial grade diamonds that are usually in three to four inch diameter pads or discs. Three to six discs are placed on the bottom of a floor machine .
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 ...
Fixed-post 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 curve-generated. 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.
