摘要
薄片(δ?3mm)零件、有色金属及非金属零件的高精度平面磨削至今尚无一种简便易行的加工方法。本文针对这类零件的结构及工艺特点,分析了各种平面砂带磨削的工艺性能,并在此基础上提出了转台式压磨板平面砂带磨削方法及相应工艺装备,对这一工艺的特点及可行性作了较详细的分析,并进行了工艺试检。结果表明,该方法克服了常规砂轮磨削的不足,加工精度高,并可提高加工效率3倍以上(有色金属和非金属件效率更高),加工成本仅与铣削相当,加工表面质量好,表面密封效果特别好。为压缩机阀片、离合器的金属与非金属摩擦片、摩托车发动机箱体、液压阀体以及塑料、胶木、橡胶等非金属板件、垫片的高精度平面加工提供了一种经济有效的工艺方法。
Taking into consideration the peculiar structure of thinworkpiece, non-ferrous metalic and non-metelic materials workpiece,the authors proposed in the paper a surface belt grinding processwith clamp plate and rotary table. Analysis is made on the feasibilityof the process. Experimental results show that, this grinding pro-cess leads to 3 times higher grinding efficiency, better ground surface,quality and lower machining cost.
