As the material for sliding guideways, metal is generally used and liquid mineral oil is supplied as the lubricant. However these result in the temperature rise during high-speed operations due to the viscous friction. Moreover, there are growing trends for oil-less guideways for uses in extreme environmental conditions such as high temperature, high vacuum and cleanliness as well as growing interests in the recent years in environmental issues. The purpose of this study is to develop lubricant-free sliding guideways for machine tools by applying solid lubricants. The study was carried out in following research items;(1) Investigation of the trend of the research of a solid lubricant.(2) Development of a special experimental device which provides a plane on plane contact condition in order toevaluate the tribological characteristics of various composite materials under the same sliding condition of practical machine tool tables.(3) Evaluation of the tribological characteristics of various composite materials(4) Development of a pneumatic half-floating contact mechanismThe result obtained in this study are summarized as follows;(1) PTFE added epoxy synthetic resin shows the excellent performances in the frictional characteristics..(2) By applying the pneumatic half-floating contact mechanism, the composite materials show high wear-resistance characteristics that can satisfy a practical use.(3) The content of PTFE in epoxy synthetic resin strongly influences on the friction and wear characteristics of slideways.

作为滑动导轨的材料，通常使用金属，并提供液体矿物油作为润滑剂。然而，由于粘性摩擦，这些导致在高速操作期间温度升高。此外，无油导轨用于极端环境条件（如高温、高真空和清洁度）的趋势日益增长，近年来对环境问题的关注也日益增加。本研究旨在应用固体润滑剂开发无润滑之机床滑动导轨。本论文主要进行了以下几个方面的研究：（1）固体润滑剂的研究趋势。(2)研制了一种专用的试验装置，提供了一种平面对平面接触条件，以评价各种复合材料在实际机床工作台相同滑动条件下的摩擦学特性。(3)（4）气动半浮动接触机构的研制本研究的主要结果如下：（1）添加聚四氟乙烯的环氧树脂复合材料具有优良的摩擦特性。(2)采用气动半浮动接触机构，复合材料具有较高的耐磨性能，能够满足实际应用的需要。(3)PTFE在环氧合成树脂中的含量对导轨的摩擦磨损特性有很大影响。
