随着机床高速高精度的技术发展，热问题已成为影响机床特性的重要因素。从提高机床的固有热性能出发，系统介绍了机床热特性分析、热结构优化及其冷却技术的理论和方法，以及国内外研究现状，并探讨了机床“热设计”理论与技术的最新进展和未来研究重点及趋势。

Based on how to improve the inherent thermal performance of high speed high precision machine tools, theories and methods about thermal characteristic analysis, thermal structure optimization and cooling technology were introduced systematically in this paper. In order to provide reference for machine tools researchers and designers, the latest progress and technology on thermal design of machine tools were reviewed and research emphasis and directions were also discussed.
