为了铣削图1所示的长半圆销,我们在铣床上做了一套跟刀架(图2),实践效果很好,提高效率4～6倍。工件12装夹在钳口1内,要轻微的夹紧,以防止工件弯曲变形,工件12主要靠两个顶柱9在弹簧10的作用下,压紧在钭铁2上,两个顶柱距离铣刀越近越好。跟刀架装在铣床横梁6上,始终跟着铣刀移动,并保持一定的压力。由于工件
In order to mill the long semi-circular pin shown in Figure 1, we made a set of heel holder on the milling machine (Figure 2). The practical effect is good and the efficiency is improved by 4 ~ 6 times. The workpiece 12 is clamped in the nip 1 and needs to be slightly clamped to prevent the workpiece from being bent and deformed. The workpiece 12 is mainly pressed against the iron bar 2 by the two top pillars 9 under the action of the spring 10, and the two top pillars The closer the milling cutter, the better. Turret mounted on the milling machine beam 6, always follow the cutter move, and maintain a certain pressure. Due to the workpiece
