摘 要

本文主要介紹了有關(guān)CBN樹脂砂輪結(jié)構(gòu)與性能的分析.空調(diào)壓縮機(jī)氣缸活塞專用CBN樹脂砂輪要求有良好的性能才能達(dá)到理想的加工效果.然而提高樹脂磨具質(zhì)量需要從其結(jié)構(gòu)和性能來(lái)分析影響砂輪質(zhì)量的因素,才能找到改進(jìn)CBN樹脂砂輪質(zhì)量的配方工藝,使國(guó)內(nèi)加工高精度零件達(dá)世界先進(jìn)水平.

我們選用三種國(guó)外進(jìn)口酚醛樹脂作為結(jié)合劑，設(shè)計(jì)首先是對(duì)這三種酚醛樹脂作一系列的物理化學(xué)性能分析，包括熔點(diǎn)、固化時(shí)間、流動(dòng)性；接著通過(guò)綜合熱分析和紅外光譜實(shí)驗(yàn)對(duì)三種樹脂的化學(xué)結(jié)構(gòu)進(jìn)行推斷；然后做樹脂樣條檢測(cè)結(jié)合劑的強(qiáng)度硬度以及檢測(cè)砂輪的抗沖擊強(qiáng)度和硬度,這些可以用來(lái)檢驗(yàn)樹脂對(duì)磨料的結(jié)合能力；最后用這三種樹脂所做的CBN砂輪完成一系列的磨削實(shí)驗(yàn)，確定其磨削性能。

Title  Structural and Functional Research on Air-condition compressor Gas Cylinder, Piston specialized CBN resin Grinding wheel            

This paper mainly analyzes the structure and function of CBN Resin Grinding wheel.

Air-condition compressor Gas Cylinder ,Piston specialized CBN resin grinding wheel. must have perfect functional to reach ideal processing effect.  For the quality improvement, structural and functional factors that affect the quality of grinding wheel should take into consideration. With the perfect processing prescription for improving the quality of CBN resin grinding wheel, the technique skill for home processing field on high finish components can catch up with the world level.

We chose three foreign imports as a phenolic resin binder to experiment. Design is the first of three this phenolic resin as a series of physical and chemical properties, Including melting point, curing time, mobility ，Then through the integrated thermal analysis and infrared spectroscopy of three resin chemical structure inference; For the kind of resin binder can detect the strength and hardness; Detection Wheel impact strength and hardness resin can be used to test the combination of abrasive; Finally, the three resins done CBN wheel grinding completed a series of experiments to determine grinding performance.
