Object of the invention can be realized by the following technical scheme:A kind of high temperature resistant pcb board drilling tool, feature exist
In this drilling tool includes handle of a knife column and the blade column being connected with handle of a knife column, and helicla flute one is offered on the blade column, described
There is rotary cut sword one directed downwardly on the upper side wall of helicla flute one, helicla flute two, the helicla flute are further opened on the blade column
There is rotary cut sword two upward, the helicla flute one is parallel with helicla flute two, the helicla flute one and spiral in two lower wall
It is connected by several radiating grooves between slot two, the radiating groove is parallel with the axis of blade column.
Helicla flute one is responsible for that pcb board is fed and cut, and rotary cut sword one is arranged at the upper side wall of helicla flute one,
Helicla flute two is responsible for carrying out burr removing to pcb board, and rotary cut sword two is arranged in the lower wall of helicla flute two, in cutter return
In the process, the downward flash and burr formed in feeding and cutting process is removed, makes processing effect and precision higher.
It is arranged using double thread, and offers several radiating grooves between helicla flute one and helicla flute two, makes blade column table
The deleted areas in face is more, good heat dissipation effect.
In a kind of above-mentioned high temperature resistant pcb board drilling tool, the both ends of the radiating groove extend through helicla flute one
The upper side wall of lower wall and helicla flute two.
The lower wall of helicla flute one is to be not provided with the position of rotary cut sword one, and the upper side wall of helicla flute two is to be not provided with rotation
Cut the position of sword two, radiating groove opens up therebetween, cutter downlink feed when, waste residue by helicla flute one effect have to
On the trend emerged, fairly fall in radiating groove, and when cutter uplink deburring, waste material is less, downlink, also falls into radiating groove
It is interior, to make radiating groove that there is better discharge effect, discharge effect, that is, waste material will not cause additional wear, heat dissipation effect to cutter
Fruit also gets a promotion, furthermore, this setting makes radiating groove not impacted to the intensity of rotary cut sword one and rotary cut sword two.
In a kind of above-mentioned high temperature resistant pcb board drilling tool, the lower end of blade column is run through in the lower end of the helicla flute one
Face has spacing between the lower end and the lower face of blade column of the helicla flute two.
This setting, during capable of avoiding feeding drilling, helicla flute two causes resistance to direction of feed.
In a kind of above-mentioned high temperature resistant pcb board drilling tool, there is auxiliary knife edge, institute in the one side wall of the radiating groove
The direction for stating auxiliary knife edge is opposite with the direction of rotation under blade column feeding state.
Goal of the invention that there are one the present invention, in order to solve the problem of that pcb board hole wall out-of-flatness burr is difficult to;
The object of the invention is achieved through the following technical solutions:
A kind of pcb board boring method, which is characterized in that this method includes the following steps:
A, it drives this cutter to rotate, cutter is made to drill to pcb board with opposite reversed in the direction of rotation of thread groove one;
B, after the completion of hole to be drilled, opposite direction rotary cutter when drilling, and at the uniform velocity move up, it can by auxiliary knife edge pair
The remaining elongated burr of energy is purged;
C, cutter is inserted into from new in processing hole, the rotation of pause cutter, drives after so that blade column is fully inserted into processing hole
Make cutter along aperture direction move up and down it is several so that rotary cut sword two is cut the tubbiness burr in hole wall back and forth, and
Modify the injustice of hole wall;Complete the drilling processing of pcb board.
