  • Ultrafine grinding of silie materials under the use of new resin

    Various processingexperiments were carried out, regarding different silie materials such as BK7® and fused silica. Among other results it is shown, that good surface qualities with low roughness down to Ra = 8 nm or Rq = 10 nm can be achieved so far, a quality that already allows speaking of "ultrafine" grinding.
