Examples
- By using high toughness fiber and fine grit which combined by special bond . used for irregular shap workpiece line grains treatment , every kinds of metal grains and grains treatment after plating , wood lines and other wood wares
造用于不规刚形状的工件上作直线的砂处理，各类金属砂光或电镀后拉砂纹处理，木线条或木相架等木器的打磨，去除毛刺和底漆处理，强韧耐用。 - By using high toughness fiber and fine grit which combined by special bond , the products are used to clean metal surface and cycle angles , grinding stainless steel with special grit grains , and will not make dark spots one the workpeice surface , and will not change the size of the the workpeice . it has high cutting force and long life time ( having different colors )
采用高韧度纤维和精选矿砂再经由特制粘胶复合而成，该产品用于清除金属刺和磨圆边角，研磨不锈钢特别砂纹，绝对不会烧黑工件表面，不会改变工件尺寸，有特强的高切削力和耐用等特点（配备红灰两色） 。 - The results show that , when increasing the feed rate of the grinding wheel , decreasing the rotating speed of the wafer chuck table and using coarser grit grinding wheel , the material removal rate in the wafer rotating grinding increase , the feed rate of the grinding wheel has greater influence on the material removal rate ; when suitably increasing the rotating speed of the grinding wheel , decreasing the feed rate of the grinding wheel and using finer grit grinding wheel , the wafer surface roughness can be reduced ; there exists a critical rotating speed of the grinding wheel ( about 2300rpm ) , beyond which the material removal rate evidently decreases and the spindle motor current and wafer surface roughness steeply increase ; when the grit size of the grinding wheel is finer than # 2000 , the material removal rate decreases and the wafer surface roughness has no obvious improvement
研究结果表明，增大砂轮轴向进给速度和减小工件转速，采用粗粒度砂轮有利于提高磨削矽片的材料去除率，砂轮轴向进给速度对材料去除率的影响最为显著；适当增大砂轮转速，减小砂轮轴向进给速度，采用细粒度砂轮可以减小磨削表面粗糙度；在其它条件一定的情况下，砂轮速度超过一定值会导致材料去除率减小，主轴电机电流急剧增大，表面粗糙度变差；采用比# 2000粒度更细的砂轮磨削时，材料去除率减小，矽片表面粗糙度没有明显改善。 - Samll grinding products , the steel ring in the middle of the grinding dish is used to fix into the hand grinding machine . it is easy to be used and have long life time by using high toughness fiber and fine grit which combined by special bond
