摘 要

本文主要介紹了有關CBN樹脂砂輪結構與性能的分析.空調壓縮機氣缸活塞專用CBN樹脂砂輪要求有良好的性能才能達到理想的加工效果.然而提高樹脂磨具質量需要從其結構和性能來分析影響砂輪質量的因素,才能找到改進CBN樹脂砂輪質量的配方工藝,使國內加工高精度零件達世界先進水平.

我們選用三種國外進口酚醛樹脂作為結合劑，設計首先是對這三種酚醛樹脂作一系列的物理化學性能分析，包括熔點、固化時間、流動性；接著通過綜合熱分析和紅外光譜實驗對三種樹脂的化學結構進行推斷；然后做樹脂樣條檢測結合劑的強度硬度以及檢測砂輪的抗沖擊強度和硬度,這些可以用來檢驗樹脂對磨料的結合能力；最后用這三種樹脂所做的CBN砂輪完成一系列的磨削實驗，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.
