长期以来,镗工的操作是靠锤子和卡钳,每镗一刀都要经过敲刀头、走刀试切、及测量三个步骤。敲刀凭经验,而走刀试切是盲目的。不仅浪费时间,而且加工精度也难保证。近年来,虽相继研制了一微动镗刀头,但使用范围大多在φ150 mm以下。 随着数显技术在镗床上的应用,我们研制了数显 For a long time, boring workers operate by hammer and caliper, each boring knife to go through the knife head, cut and cut, and measure three steps. Knife with experience, and cut the knife test is blind. Not only a waste of time, but also difficult to guarantee the accuracy of the processing. In recent years, although have developed a micro-moving boring head, but most of the use of φ150 mm below. With the digital display technology in the boring machine, we developed the digital display
