中文摘要
　　自1970年以來，靜壓滑軌在工作母機工業上，已獲得廣泛的應用，此乃因其本身所具的優點，以及設計技術的改善，克服了重型機具精密定位受摩擦所發生的問題，而且根據世界先進國家磨床工具機製造廠的報告，使用靜壓滑軌的工作床台，在運轉十年後，仍無摩耗至需鏟花修護的地步。。
本文重點為設計－個可適用於精密外圓磨床之靜壓滑軌，並以我國榮光機械公司所提供GUP-32100外圓磨床為對象，將其原本強制供油潤滑的滑軌，先量測滑軌靜態油膜及動態狀況，並分析其剛度與因負荷變化的關係，以及滑板低速位移所產生stick-slip情況，而針對滑軌原有的缺失，設計以毛細管節流供油潤滑之靜壓滑軌，再以實驗探討靜壓滑軌的靜態特性及動態特性，並與原始滑軌的特性作比較，以確認靜壓滑軌之商品化可行性，作為磨床滑軌改善，提昇精度之參考。

Abstract
Because hydrostatic slideways have absolutely merits and the improvements of technologies in their design, Since 1970 hydrostatic slideways have been widely used by the machine tool . According to the recently reports of the grinder machinery companies in developed countries, the machines , which are equipped with hydrostatic slider and slideways , could been run continuously for a decade without any maintaining.
This study has emphasized on the design method of hydrostatic slideways, which can be used by the precision cylindrical grinding machines. First of all, in order to measure the characteristics of the cylindrical grinding machine －GUP-32100 made by PARAGON machinery company－such as static oil film of slider, stiffness, loading dynamic system and stick-slip friction system, we applied the capillary restriction hydrostatic slideways to the cylindrical grinding machine and then experimentally analysed the statistic characteristics and loading dynamic system of the capillary restriction hydrostatic guide ways. After comparing the characteristics of capillary restriction hydrostatic guide ways to the characteristics of non-capillary restriction slider, we can find the differences of them and ,in order to improve the precision of machinery, make it as a reference for the technologies of hydrostatic slideways’ design.
