硬脆材料雙面研磨/拋光機的設(shè)計
摘要：雙面平面研磨是在傳統(tǒng)研磨機構(gòu)的基礎(chǔ)上，通過改變研磨平面的數(shù)目從而來提高研磨精度和效率的一種研磨方式。其加工原理就是利用涂敷或壓嵌在研具上的磨料顆粒，通過研具與工件在一定壓力下的相對運動對加工表面進行精整加工，從而來實現(xiàn)加工精度的要求。
本文通過對平面研磨機構(gòu)多種運動方式的分析，以及研磨精度要求，并結(jié)合現(xiàn)有研磨機，從而設(shè)計出一種新型的行星式雙面平面研磨機構(gòu)，并對其運動軌跡做了具體研究。這種研磨方式不僅解決了傳統(tǒng)研磨存在加工效率低、加工成本高、加工精度和加工質(zhì)量不穩(wěn)定等缺點，提高了研磨技術(shù)水平，保證研磨加工精度和加工質(zhì)量，而且還可以實現(xiàn)在一定范圍內(nèi)不同直徑圓柱工件的研磨，提高了加工效率，降低了加工成本，使研磨技術(shù)進一步實用化。
Double-sided Grinding Of The Hard-brittle Materials/Polishing Machine Design
Abstract：
Double-sided plane grinding is the traditional grinding institutions, and on the basis of the number of by changing the grinding plane to improve the grinding efficiency and precision of a kind of grinding way. Its processing principle is to use the coating or pressure with embedded in the research on the abrasive particles with and workpiece, through research in the relative movement under certain pressure of machining surface finish machining, thus to realize the machining accuracy of requirements.
This thesis through to plane grinding institutions of various sports mode analysis, and grinding accuracy requirement, and combine existing grinding machine, thus designed a new double plane grinding mechanism, and to its trajectory made specific research. This kind of grinding way not only solves existing traditional grinding machining efficiency is low, the processing cost, high machining accuracy and processing quality unstable shortcomings, improves grinding technology level and guarantee of grinding accuracy and processing quality, but also can realize within the scope of certain and different cylinder workpiece, improves the grinding machining efficiency and reduce the processing cost, make grinding technology further practional utilizati
