机械抛光是利用布轮或毛毡轮的高速旋转和摩擦,及不断添加抛光膏剂,使工件不断被抛光。这虽能满足我厂电位器板条的加工要求,但抛后需用大量的汽油洗净充塞在绕组间的抛光膏剂方可使用。一则绕组缝隙清洗困难;二则需用大量汽油和工时;三则空气污染严重。现在我们将抛光膏剂及磨料混合在橡胶中,制成弹性好、有一定硬度、抛光迅速、抛后不需清洗的弹性抛光轮。配方:5860丁腈橡胶:100克,基体材料;
Mechanical polishing is the use of cloth wheels or felt wheel high-speed rotation and friction, and continue to add polishing paste, so that the workpiece is constantly polished. Although this can meet the processing requirements of our factory potentiometer slats, but after the thrown need to use a lot of gasoline washed stuffed between the winding polishing paste before use. A winding gap cleaning difficulties; two require a lot of gasoline and working hours; three serious air pollution. Now we will be polishing paste and abrasive mixed in the rubber, made of good elasticity, a certain hardness, polishing quickly, after throwing without cleaning elastic polishing wheel. Formula: 5860 nitrile rubber: 100 grams, matrix material;
