Description

図2に目詰まりした砥石表層の断面図を示す。一般的な使用状態では砥粒(固定砥粒)の突き出し量は、砥粒(固定砥粒)の径の1/5から1/3程度である。この場合にガラス粉の目詰まり除去を効率的に行うには、砥粒(固定砥粒)の突き出し量の1〜2倍の粒径の研磨剤砥粒を研削液中に含有させればよい。つまり、研削液中に含有させる研磨剤砥粒の好ましい粒径範囲は、式(1)で表すことができる。ここで、粒径は体積換算し球体としたときの径である。 FIG. 2 shows a cross-sectional view of the clogged grindstone surface layer. In a typical use conditions overhang of abrasive (fixed abrasive) is abrasive 1/5 to about 1/3 of the diameter of the (fixed abrasive). In this case, in order to efficiently remove the clogging of the glass powder, the abrasive abrasive grains having a particle size of 1 to 2 times the protrusion amount of the abrasive grains (fixed abrasive grains) may be contained in the grinding fluid. .. In other words, the preferable range of the particle size of the abrasive grains to be contained in the grinding fluid can be represented by the formula (1). Here, the particle size is the diameter when converted into a sphere by volume.
