影響研磨盤機械性質之參數探討

Abstract

摘 要

本研究主要是探討磨粒/環氧樹脂基研磨盤材料在不同製程參數下的變異對於機械性質所造成的影響，機械性質測試包括拉伸、磨耗等實驗。

結果顯示在於溫度60℃與80℃固化凝結成型的磨盤，其拉伸試驗之楊氏模數差異性並不大，但對於溫度100℃固化凝結成型下的磨盤明顯楊氏模數下降約有10％。

磨耗試驗結果得知隨著固化凝結成型磨盤溫度的提升，溫度升越高磨盤強度則越強，磨盤耗損率則就越低。

利用掃描式電子顯微鏡(SEM)進行磨料顆粒在研磨盤材料的分散性探討，結果顯示環氧樹脂含量在25％結合磨粒時，發現磨盤材料有明顯的團聚現象，此現象會間接影響到磨盤材料整體結構的強度。

ABSTRACT

This study explores the influence that variations of abrasive grains and epoxy-based materials in different process parameters have on the mechanical properties of lapping plate. Mechanical properties can be examined using methods such as tensile and abrasion tests.

Based on the tensile test results, the Young’s modulus of the lapping plate solidified and formed at 60 °C and 80 °C did not show substantial differences. However, the Young’s modulus of the lapping plate solidified and formed at 100 °C significantly declined by approximately 10%.

Based on the abrasion test results, wheel strength increased and wheel wear decreased following an increase in the solidification temperature for the lapping plate.

The analysis results of abrasive grain dispersion on the lapping plate material using scanning electron microscopy indicated that 25% epoxy content combined with abrasive grains demonstrated a clear agglomeration, which indirectly affected the overall structural strength of the lapping plate material.
