摘　　要："以车代磨"切削加工淬硬材料,经济优势明显。使用涂层硬质合金刀具材料车削淬火45钢,合理的刀具几何参数,恰当的切削用量,是保证车削顺利实现的关键。实验证明,使用涂层硬质合金刀具,采用较高的切削速度,吃刀深度ap≤0.1mm、进给量f≤0.1mm时,车削淬火45钢可以达到表面粗糙度R≈0.2～0.5μm,刀具耐用度与车削非淬火钢时相当,可以代替磨削加工。＂Grinding being substituted for turning＂ cutting quenching steel, the economic benefits is obvious. Turning quenching 45 steel by coating categories of cemented carbide tools, the reasonable tools geometric parameters and the appropriate cutting parameters are the turning key. Proved through the experiments, when the turning has the high cutting speed, the cutting depth αp ≤0. 1 mm and feed speed f≤ 0. 1 mm by coating categories of cemented carbide tools, the turning quenches 45 steel will get the surface quality of workepiece for Ra≈ 0. 2 - 0. 5μm, and the cutting tools have reasonable cutting life- time.
