【摘要】 对天然金刚石切削黑色金属的磨损机理进行了分析 ,提出了天然金刚石超声振动结合气体保护方法对黑色金属材料进行微量切削的新思路 ,并进行了不锈钢零件的切削实验。实验表明 ,当切削路程达到 2 0 0 0m时 ,工件表面粗糙度Ra小于 0 .15 μm ,后刀面磨损带宽小于 5 μm。更多还原

【Abstract】 This paper analyzes the wear mechanism of diamond cutting tool in machining of steel. We first review the principle of diamond turning of ferrous metals applying ultrasonic vibration combined with gas shield. The experiments of cutting stainless steel parts is made, showing that the surface roughness Ra is less than 0.15μm and flank wear-width is less than 5μm, up to 2000m in the cutting distance.更多还原
