Was doing a lot with the surface grinder and every now and then, you want to look at the wheel coming in contact with the piece to see if things are on track. Of course, sticking your head in there is a good way of ending your life or your vision so, here's a handy safety tip. …

Mirror grinding is a grinding that the surface roughness of the workpiece is Ra< 0.01μm, and the light is like a mirror after grinding, so it can be clearly photographed. The flatness of the grinding surface is not greater than 3μm /1000mm. The surface machining of high precision and high added value parts requires mirror grinding. 2.

An apparatus and a method for mirror surface grinding which enables high quality, stable ELID grinding; and a grinding wheel for electrolytic dressing. The apparatus comprises a grinding wheel 3 having a contact surface 2 for contacting a workpiece 1, an electrode 4 facing the surface 2, nozzles 5 for supplying conductive fluid between the grinding wheel 3 and the …

After more than six years of grinding and polishing, the first-ever dual-surface mirror for a major telpe is complete. In March 2008, a group of people gathered around a giant, red oven in a six-story workshop space beneath the bleachers of the University of Arizona football stadium.

Page 1 of 2 - How to hold convex mirror blank for grinding? - posted in ATM, Optics and DIY Forum: I obtained a mirror blank that had been previously used for grinding another mirror, so one side is convex and one side is flat. Rather than hogging out the convex side, I plan to grind on the flat side. But, Im trying to figure out the best way to hold the blank …

Can produce a mirror surface equivalent to super-finishing through grinding alone. Polishing work such as wrapping and super-finishing processes eliminated, facilitating shortening of the …

Rough grinding a telpe mirror. The Joy of Mirror Making Mel Bartels Rough Grinding The first milestone is putting a curve into the mirror face. ... Geometrically, two surfaces when rubbed against each other, must create a concave sphere on …

Therefore, such surfaces are suitable for certain unmachined clearance areas. 12.5: 500: These are rough, low-grade surfaces resulting from coarse feeds and heavy cuts. While the cuts come from turning, milling, disc grinding, and more. 6.3: 250: This type of surface finish results from surface grinds, disc grinds, milling, drilling, and more.

Mirror Surface Finishing Large-size Machining + Surface. Mirror surface finishing is the grinding method to polish the metal surface into mirror-like surface by vertical grinding or buff grinding. In order to polish the surface into mirror-like surface, face roughness as well as face accuracy as swelling becomes required.

A mirror surface grinding method processes an optical glass material into a lens shape using a cup-shaped grinding stone. The grinding stone is pupplied with a polishing solution which contains charged fine particles, thereby electrically attaching the charged fine particles to the grinding stone.

The steel-bonded cemented carbide is subjected to mirror grinding, and the surface roughness of the workpiece is Ra=0.003 μm～0.011 μm. If a finer grinding wheel (above W1) is used, the Ra value will be significantly reduced and a better surface roughness will be obtained.

Mirror grinding is a grinding that the surface roughness of the workpiece is Ra< 0.01μm, and the light is like a mirror after grinding, so it can be clearly photographed. The flatness of the grinding surface is not greater than 3μm /1000mm.

This study has been focused on application of ELID mirror-surface grinding technology for manufacturing single crystal optic sapphire. Single crystal sapphire is a superior material with optic properties of high performance as light transmission, thermal conductivity, hardness and so on. Mirror-surface machining technology is necessary to use sapphire as optic parts.

Place the mirror on the tool. Start with chordal stroke to grind the mirror's center and tool' edge. After every few minutes, turn the tool clockwise 30 degree and mirror anticlockwise 30 degree. Continue grinding with at-least 12 wets. Once done, wash mirror and tool and inspect the Mirror's surface.

Mirror Grinding at the Spring 1998 Stellafane Mirror Workshop in the McGregor Observatory Rough Grinding. The purpose of rough grinding is to start to cut a spherical concave surface into the mirror blank. For a 6" mirror with a 48" focal length, the depth of the curve is 0.047".
