摘要
介绍了BTA钻的分屑形式与钻削过程,进行了BTA钻的深孔钻削试验,分析了单齿钻和错齿钻的钻削过程及形成的孔底形状,并分别对比分析了单齿钻和错齿钻的切屑形态及钻削力。结果表明:与单齿钻相比,错齿钻分屑效果较好且定心作用较强,但切屑形态不佳,堵屑现象严重;错齿钻的钻削力小于单齿钻,钻削过程比较稳定。
Chip-separating form and drilling process of BTA drill are introduced and the deep hole drilling experiments of BTA drills are carried out.The drilling process of single tooth and staggered teeth drill are analyzed,as well as the shape of hole is formed.The chip morphology and drilling force of single tooth and staggered teeth drill are compared.The results show that,compared with the single tooth drill,the chip-separating effect of staggered teeth drill is better,and its centering effect is stronger.But its chip morphology is not good,and the chip-blocking phenomenon is serious.The drilling force of the staggered teeth drill is less than that of single tooth drill,and its drilling process is relatively stable.
