、幾何形狀粗度及表麵粗糙度
，但不能提高密封麵各表麵間的相互位置精度。研磨後的閥門密封麵通常可以到的尺寸精度為 0.001~0.003mm；幾何形狀精度（如不平度）為 0.001mm；表麵粗糙度為 0.1~0.008，密封麵研磨的基本原理包括研磨過程、研磨運動、研磨速度、研磨壓力及研磨餘量五個方麵。

，銅及鑄鐵密封麵的研磨速度為 10~45m/min
；淬硬鋼及硬質合金密封麵為 25~80m/min
；奧氏體不鏽鋼密封麵為 10~25m/min。

、研磨壓力，研磨效率隨研磨壓力的增大而提高
，研磨壓力不能過大，一般為 0.01～0.4MPa
，研磨鑄鐵、銅及奧氏體不鏽鋼材料的密封麵時，研磨壓力為 0.1~0.3MPa；淬硬鋼和硬質合金密封麵為 0.15~0.4MPa。粗研時取較大值
，精研時取較小值。
