The Grinding Guru takes a few strokes on my mirror "It's not bad," he says After a few hours of this, I get my first taste of what this work is all about. We take my mirror outside and reflect an image of the sun onto a piece of paper.

The influence of cut and extreme additives including in cutting fluid on the mirror traverse grinding characteristics of aluminum alloy, in the present research, is examined. The experiments are executed using the resinoid bonded

title = "High-efficiency mirror grinding of AlN by ultra-precision plane honing", abstract = "Plane honing machining of aluminum nitride (AlN) was investigated in this study. AlN has advantageous thermal and dielectric characteristics and is in great demand as a semiconductor mounting board or packaging parts material.

This research was done to improve the controllability of the mirror grinding process by proposing the effective method to keep good wheel performance during grinding by generating and evaluating the working surface condition.First of all, the generation process of the working surface with dressing was examined based on the change in …

2002/01/01· Ultraprecision mirror surface grinding, which achieved a surface roughness of 0.007 microns in Ra and surface straightness of 0.25 microns for a metal mold steel, was stably realized. Discover the ...

Currently, we are striving to research and develop grinding wheels for mirror finishing of hard and brittle materials as P Series products. SHIN-EI GRINDING WHEELS are considered about quality, safety and environmental conservation …

In order to realize the skill-free mirror grinding process, five research themes are examined in this study : 1) Generalization of on-machine measurement system of working surface profile of grinding wheel, 2) Establishment of the quantification method of the grain cutting-edge density, 3) Grasp of the change of the grain cutting-edge …

1996/07/01· Fine ceramics have the properties of high hardness, chemical inertness, high thermal resistance and low electrical conductivity, but, because of high hardness and brittleness, they are very difficult to machine. Therefore, a superabrasive diamond wheel is used for mirror-like grinding of this material. In this study, an in-process electrolytic dressing system for carrying out mirror …

1996/01/31· The mirror freeform grinding may be parameterized by material behavior, tool size and posture, grinding conditions and abrasive tool performance. On the base of virtual ball-end algorithm, the ...

1994/02/01· Use of a diamond wheel with superabrasive is required for mirror-like surface grinding of brittle materials. However, conventional dressing methods cannot apply to the diamond wheel with superabrasive. Recently, an electrolytic dressing method was developed for use with a cast iron-bonded diamond wheel and superabrasive. …
