以往,在切削φ12～16mm孔时,由于受刀杆尺寸的限制,未能采用机夹刀具。采用焊接刀具,刀杆将随刀片磨损后的反复刃磨,到一定程度(经测试一般磨去1/3)而报废,造成刀杆大量浪费。针对这个问题,我们经多次反复试验,革新成功如图所示的机夹小型镗孔刀。通过一年多的使用,证明此刀具适应范围广、更换刀片容易,可切削多台阶的孔及通孔,起到一杆多用的作用。
In the past, in the cutting φ12 ~ 16mm hole, due to the size of the arbor limit, failed to use the machine tool. The use of welding tools, arbor blade wear with repeated blade sharpening, to a certain extent (the test generally wear to 1/3) and scrapped, resulting in a large number of knife bar waste. In response to this problem, we have repeatedly tested, the success of innovation as shown in the machine folder small boring knife. Through the use of more than a year to prove that this tool to adapt to a wide range of blade replacement easy, multi-step cutting holes and through-hole play a multi-purpose role.
