摘要
分析了小直径深孔振动钻削对钻头的要求;设计了一种新型内排屑深孔钻头;分析了该钻头的结构和刃磨特点,进行了振动钻削试验。试验表明,合理匹配切削参数和振动参数,可实现断屑可靠且排屑顺畅,能钻出尺寸精度高、表面粗糙度参数值小、直线度较高的深孔。分析了用新型钻头进行振动钻削提高工艺效果的原因,表明该种钻头具有良好的工艺性能。
Based on analyzing the demands of small-diameter deep-hole drill for vibration drilling, a new inner-chip removal drill was designed. The structures and tool grinding features were analyzed and vibration drilling experiments were done. Matching the cutting parameters and vibration parameters, it can achieve reliable chip breaking and smooth chip disposing, and the drilled deep-hole has high dimensional precision, small surface roughness values and small linearity errors. The reasons of technical effects improved by vibration drilling using the new drill were analyzed. It shows that the drill has good and reliable technical performance.
