Research Progresses of Mechanical Dressing for Arc Diamond Grinding Wheels
弧形金刚石砂轮因特有的弧形轮廓,常用于陶瓷、光学玻璃、硬质合金等难加工材料光学元件的精密超精密磨削加工.然而,在光学元件磨削加工过程中,由于砂轮与工件表面间的相互作用,砂轮表面受到挤压破坏,长时间磨削后会产生砂轮堵塞、砂轮磨损、砂轮尺寸和形状精度下降等问题,进而降低了磨削后光学元件的表面粗糙度、面形精度和损伤厚度等.修整弧形金刚石砂轮是解决上述问题的有效途径之一,机械修整因具有修整效率高、便于实现等特点,仍是弧形金刚石砂轮在位修整的主要应用方法.对弧形金刚石砂轮的机械修整方法进行了综述,探究了不同修整方法的修整机理与特点,分析了修整效果的评价方法,并对弧形金刚石砂轮机械修整的发展方向进行了展望.
The arc diamond grinding wheels had unique arc profile and commonly used for preci-sion and ultra-precision grinding of optical components made from difficult-to-cut materials such as ce-ramics,optical glass,and cemented carbide.However,during the grinding process of optical ele-ments,the interaction between the grinding wheel and the workpiece surface caused the abrasive grains on the grinding wheel to be squeezed and damaged.Then,this led to issues such as grinding wheel blockage,wear,reduction in size and shape accuracy,ultimately affecting the surface rough-ness,shape accuracy,and damage thickness of the optical elements after grinding.To address these problems,dressing the arc-shaped diamond grinding wheel was an effective solution.Among the vari-ous dressing methods,mechanical dressing remained the primary approach in production due to the high dressing efficiency and ease of implementation.This paper provided a comprehensive review of the mechanical dressing methods for arc diamond grinding wheels.The truing mechanism and charac-teristics of different methods were explored,the evaluation method for truing effectiveness was ana-lyzed,and a future outlook for the mechanical truing of arc diamond grinding wheels was presented.
