常見例句雙語例句In the grinding, if they are grinding the workpiece material, high hardness, low abrasive hardness is generally used;在磨削加工中，若被磨工件的材質(zhì)硬度高，一般選用硬度低的磨具；Abrasive hardness measurement method, more commonly used are hand-cone method, mechanical cone method, Rockwell hardness tester hardness measurement method and blasting assay.測定磨具硬度的方法，較常用的有手錐法、機(jī)械錐法、洛氏硬度計(jì)測定法和噴砂硬度計(jì)測定法。Abrasive hardness depends primarily on the amount of binding agent to join the number and density of abrasive, abrasive easy to fall off the expression of abrasive hardness is low;磨具的硬度主要取決於結(jié)郃劑加入量的多少和磨具的密度，磨粒容易脫落的表示磨具硬度低；blog.sina.com.cn 返回 abrasive hardness
