一般镗床刀杆进刀时,往往采用敲刀的办法。如果精镗时需要刀尖一次进给量在0.0025～0.005毫米时,即使是工作多年有经验的老师傅,一锤也敲不出准确的尺寸来。如果来回敲刀,就太费时间,当孔的位置在里面时,敲刀还很困难。针对这种情况,我们设计制造了一种T6100型微调刀体,可提高精镗效率二倍以上。结构如图所示。微调时,先松开内六角螺钉9,拧动微调螺杆7,从 General boring machine tool knife into the knife, often using knocking approach. If the fine boring need a tool tip feed in the 0.0025 to 0.005 mm, even for many years of experience in the old master, a hammer can not knock out the exact size. Knocking the knife back and forth can take too much time and it can be difficult to knock the knife when the hole is inside. In view of this situation, we designed and manufactured a T6100-type fine-tuning body, can improve the precision boring more than twice the efficiency. Structure as shown. Fine-tuning, first loosen the hexagonal screw 9, screw the fine-tuning screw 7, from
