Abstract

Diamond, with its unparalleled combination of physical and chemical attributes, occupies a critical role in future technological domains; yet, the caliber of its surface quality is decisively linked to its performance within advanced applications. Thus, engaging in super-precision processing to elevate the surface integrity of diamond constitutes a central tenet for broadening its application potential. This paper systematically dissects patents pertaining to diamond polishing apparatus, not only revealing the distinctive strengths and pragmatic features inherent in contemporary diamond polishing technology but also identifying limitations and avenues for refinement within current polishing methodologies. With the continuous expansion and deepening of modern industrial sectors, there is a growing demand for diversified and specialized material performance. Diamond, as a pivotal raw material, exhibits immense potential in its composite applications with a variety of other materials, forming an entire industrial chain that has permeated numerous industries. Throughout the comprehensive preparation process of diamond, from rough stone to finished product, polishing techniques play a critical role, representing an indispensable step in enhancing the surface quality and functional attributes of diamond products. This study provides a comprehensive review of representative patents in the field of diamond polishing apparatus, analyzing the distinctive functional attributes and performance characteristics of various diamond polishing devices. The study classifies polishing devices according to their design characteristics and application domains into five distinct categories: polishing apparatuses specifically designed for single-crystal diamonds, systems tailored for the polishing of complex curved surface diamonds, laser-assisted diamond polishing setups, structurally-enhanced diamond polishing equipment, and functionally-specialized diamond polishing tools. The analysis underscores the unique innovative aspects and advantages demonstrated by each patent in addressing the inherent limitations of traditional polishing devices. Moreover, it elucidates the technological constraints and developmental gaps that exist within each respective area. Presently, the essence of polishing technology research revolves around the precision and efficacy in polishing single-crystal diamonds and intricate curved diamond surfaces, alongside the structural innovation and functional refinement of polishing apparatuses. Predominant among these devices are those that largely depend on mechanical polishing methods integrated with laser-assisted and chemical mechanical polishing methodologies, where patent advancements are mainly geared towards boosting efficiency, guaranteeing surface integrity, fortifying adaptability across different operating scenarios, and incorporating multiple functionalities. Concurrently, considerable attention is given to enhancing the ecological performance of these systems. There remains a significant underdevelopment and limited widespread application of diamond polishing apparatus in advanced technologies such as thermal chemical polishing and ion beam polishing. This gap presents an enormous potential for innovation breakthroughs and diversified advancements in polishing techniques. There is an urgent need for increased investment to propel the development and integration of automated control systems, intelligent monitoring, and deeper exploration of new materials within polishing technology. The aim is to realize higher-level automated and intelligent diamond polishing solutions that can achieve more efficient, precise, and environmentally friendly polishing objectives.
