加工圆柱工件的液动压抛光设备Hydraulic pressure polishing equipment for processing cylindrical workpieces

技术领域technical field

本发明涉及抛光设备领域，具体地涉及一种加工圆柱工件的液动压抛光设备。The invention relates to the field of polishing equipment, in particular to a hydraulic pressure polishing equipment for processing cylindrical workpieces.

背景技术Background technique

随着光学和微电子学及其相关技术的发展，对所需材料表面质量的要求越来越高，超光滑表面加工技术随之受到发展和重视超光滑表面的主要特征包括：极小的表面粗糙度；尽可能小的表层和亚表层损伤，晶体表面具有完整的晶体结构；极小的表面残余应力。With the development of optics and microelectronics and related technologies, the requirements for the surface quality of the required materials are getting higher and higher, and the ultra-smooth surface processing technology has been developed and paid attention to. The main characteristics of ultra-smooth surfaces include: extremely small surface Roughness; surface and subsurface damage as small as possible, the crystal surface has a complete crystal structure; minimal surface residual stress.

抛光加工因其材料去除量微小、加工精度高等特点，被作为超光滑表面加工的主要最终加工手段。现有应用于超光滑表面加工的抛光方法主要有直接接触式抛光、准接触式抛光和非接触式抛光。作为非接触式抛光的一种,流体抛光技术在加工过程中，抛光工具与工件不发生接触，而是利用流体驱动磨粒冲击工件表面实现材料去除，有效避免了材料的表面及亚表层损伤，既可用于功能晶体材料的抛光(注重结晶完整性和物理性能)，也可用于光学零件的抛光(注重表面粗糙度和形状精度)。Polishing is used as the main final processing method for ultra-smooth surface processing because of its small amount of material removal and high processing accuracy. The existing polishing methods used in ultra-smooth surface processing mainly include direct contact polishing, quasi-contact polishing and non-contact polishing. As a kind of non-contact polishing, the fluid polishing technology does not touch the workpiece during the processing process, but uses the fluid to drive the abrasive grains to impact the surface of the workpiece to achieve material removal, effectively avoiding the surface and subsurface damage of the material. It can be used not only for the polishing of functional crystal materials (focusing on crystal integrity and physical properties), but also for polishing of optical parts (focusing on surface roughness and shape accuracy).

目前国内外针对不同的加工对象研发了液动压悬浮抛光。但是液动压悬浮抛光技术仅仅用于平面的抛光，没有应用于具有弧形表面的工件上，一个原因是弧形表面工件上难以形成稳定的液膜，另一个原因是弧形表面表面积大于平面，难以提供足够的流通的抛光液。At present, hydrodynamic suspension polishing has been developed for different processing objects at home and abroad. However, the hydrodynamic suspension polishing technology is only used for plane polishing, and has not been applied to workpieces with curved surfaces. One reason is that it is difficult to form a stable liquid film on workpieces with curved surfaces, and the other reason is that the surface area of curved surfaces is larger than that of flat surfaces. , it is difficult to provide enough circulating polishing fluid.
