    ELID Assisted Grinding of Optical Glass with Fine and

    The experimental results show that the fine and coarse grained wheels can all generated the smooth surface with the surface roughness in nanometer scale and the coarse grained diamond wheel correlates to the slightly more surface damage than the fine grained diamond wheel, which also proves that the high efficient grinding of the optical glass with a good surface quality can be realized with the coarse grained copper-resin wheel on a precision grinder and the grinding wheels

    An Introduction to the Optics Manufacturing Process

    Oct 31, 2008 Loose abrasive grinding uses inverse spheres of the same radii ground together so that the hills and valleys on the optics will wear away to produce a true sphere. Slurry flows in between the blocked parts and the spherical tool to keep the parts cool and wash away debris created during the grinding process

    Ultraprecision Grinding of Optical Glasses to Produce

    The typical 11 kinds of optical glasses have been ground by the ultra-precision surface grinder having a glass-ceramic spindle of extremely-low thermal expansion with various cup-typed resinoid-bonded diamond wheels of #200-#3000 in grain size. All kinds of glasses can be ground in the ductile mode and the surface does not contain a micro-crack

    Jan 01, 2010 Fine grained diamond grinding wheels are often utilized for the precision machining of functional surfaces in “optical quality” (regarding form accuracy and surface roughness). In particular, for a combination with metal bonded systems, high profile reliability and high wear resistance together with high material removal rates can be achieved

    The abrasive used for each succeeding grinding operation should be one or two grit sizes smaller than that used in the preceding step. A satisfactory fine grinding sequence might involve SiC papers with grit sizes of 240, 320, 400, and 600 grit [P280, P400, P800 and P1200]. This sequence is used in the “traditional” approach

    Fine grinding discs need diamond abrasive added during use. Because of their effectiveness in bringing diamonds in contact with the sample, they do neither require large amounts of diamonds nor any run-in time. With diamond suspensions you should dose about 0.5 ml/min on a 250 mm disc. Less on a 200 mm disc and more on a 300 mm disc
