Abstract
The key components of steam turbine have special material and complex structures.In their manufacturing,hole machining is an indispensable process,and High Speed Steel(HSS)twist drills is a common tool for this process.Actual cutting tests were taken on HSS twist drills produced by three manufactures,and their material properties and geometric structure parameters were analyzed.The cutting tests and analysis results show that the Walter cobalt containing HSS twist drills are the preferred HSS twist drills for processing materials of key components in steam turbine,because they have characteristics of long tool life,good machining dimension accuracy and satisfying surface quality.The research results can provide reference for selection of HSS twist drills.关键词
