Description
技术领域technical field
本发明涉及一种圆锥抛光装置,适用于光学元件、非晶薄膜衬底等工件表面的研磨与抛光加工。The invention relates to a conical polishing device, which is suitable for grinding and polishing the surfaces of workpieces such as optical elements and amorphous film substrates.
背景技术Background technique
研磨是利用涂敷或压嵌在研具上的磨料颗粒,通过研具与工件在一定压力下的相对运动对加工表面进行的精整加工(如切削加工)。研磨可用于加工各种金属和非金属材料,加工的表面形状有平面,内、外圆柱面和圆锥面,凸、凹球面,螺纹,齿面及其他型面。加工精度可达IT5~01,表面粗糙度可达Ra0.63~0.01微米。Grinding is the use of abrasive particles coated or pressed on the grinding tool to finish the processing surface (such as cutting) through the relative movement of the grinding tool and the workpiece under a certain pressure. Grinding can be used to process various metal and non-metal materials. The processed surface shapes include plane, inner and outer cylindrical and conical surfaces, convex and concave spherical surfaces, threads, tooth surfaces and other profiles. The processing accuracy can reach IT5~01, and the surface roughness can reach Ra0.63~0.01 microns.
抛光是指利用机械、化学或电化学的作用,使工件表面粗糙度降低,以获得光亮、平整表面的加工方法。利用柔性抛光工具和磨料颗粒或其他抛光介质对工件表面进行的修饰加工。抛光不能提高工件的尺寸精度或几何形状精度,而是以得到光滑表面或镜面光泽为目的,有时也用以消除光泽(消光)。Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. Modification of the workpiece surface using flexible polishing tools and abrasive particles or other polishing media. Polishing does not improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is aimed at obtaining a smooth surface or mirror gloss, and is sometimes used to eliminate gloss (matting).
当我们需要对代加工工件进行光整加工,用以改善工件表面粗糙度或强化其表面的加工过程,通常同时采用研磨和抛光。传统的利用研磨盘或者抛光盘的光整系统将研磨与抛光工序分开,使得由研磨过度到抛光时系统需要将研磨盘更换为抛光盘,很难提升加工效率。即使是单一的研磨加工,单一磨粒粒度的研磨盘也并不能使工件完全达到所需的表面粗糙度或者需要很长的加工时间。且传统的研磨和抛光系统,加工时需要人为添加砝码或由工件和承托工件的器件本身的重力来决定施加于工件表面与研磨盘(或抛光盘)表面的压力,这使得所是施加的压力不能根据加工需求得到动态调节而且无法得到低于工件和承托工件的器件本身的重力的压力,在更换研磨盘或抛光盘后需添加或者更换砝码,由于砝码的质量固定,很难实现施加压力的连续变化,从而影响了加工质量,并且受人为因素影响大,很难实现自动化。When we need to carry out finishing processing on the OEM workpiece to improve the surface roughness of the workpiece or strengthen its surface, grinding and polishing are usually used at the same time. The traditional finishing system using a grinding disc or a polishing disc separates the grinding and polishing processes, so that the system needs to replace the grinding disc with a polishing disc when transitioning from grinding to polishing, making it difficult to improve processing efficiency. Even for a single grinding process, a grinding disc with a single abrasive grain size cannot fully achieve the required surface roughness of the workpiece or requires a long processing time. Moreover, in the traditional grinding and polishing system, it is necessary to artificially add weights or the gravity of the workpiece and the device supporting the workpiece to determine the pressure applied to the surface of the workpiece and the surface of the grinding disc (or polishing disc), which makes the application The pressure cannot be dynamically adjusted according to the processing requirements, and the pressure lower than the gravity of the workpiece and the device supporting the workpiece cannot be obtained. After changing the grinding disc or polishing disc, it is necessary to add or replace the weight. Because the quality of the weight is fixed, it is very difficult It is difficult to realize the continuous change of the applied pressure, which affects the processing quality, and is greatly affected by human factors, so it is difficult to realize automation.
