How to read the broken tool record of pcb drilling machine 30

It is wrong to ask the pcb drilling machine 30 how to treat the broken tool record. The correct question is: How does the pcb drilling machine 30 view the broken tool detection? According to the inquiry, when the pcb drilling machine is drilling the plate, the drilling tool is affected by the plate material, drilling tool material itself, improper drilling file parameters, dynamic fatigue and other factors, and there will be the risk of tool cutting. For example, the fracture of the drilling tool of pcb drilling machine will not only affect the subsequent hole group processing, but also directly affect the forming quality of the plate. Therefore, it can detect whether the bit cutter is broken in real time and prompt the position of the broken cutter in time, which is an important function of pcb drilling machine to realize its pcb drilling function. In the prior art, in order to realize the real-time detection of broken knives, one of them is to use optical fiber induction to detect the machining situation of hole groups in real time. For example, in the patent application document with the patent application number of "201220261kloc-0/36.4", a broken needle detection device of a pcb drilling machine is disclosed, which comprises a drilling machine, a presser foot mounted on the drilling machine and a drilling needle located on the axis of a circular hole of the presser foot, wherein the bottom of the presser foot is provided with a first induction optical fiber and a second induction optical fiber. The sensing ends of the first sensing optical fiber and the second sensing optical fiber are located on both sides of the axis of the presser foot annular hole, and the connecting line between the first sensing optical fiber and the second sensing optical fiber vertically intersects with the axis of the presser foot annular hole.
