Abstract
The invention relates to a drilling tool for the processing of an annular groove, which comprises a tool handle and a tool bit, wherein the tool bit is arranged at the lower end of the tool handle, a chip discharging groove is formed in the side wall of the tool bit, an outer tool blade is arranged on the edge of the chip discharging groove, a cutting groove is formed in the end part of the tool bit, an inner tool blade is arranged on the side wall of the cutting groove, the outer tool blade is used for processing the outer sidewall of the annular groove, the inner tool blade is used for processing the inner sidewall of the annular groove, the outer tool blade and the inner tool blade cut a workpiece in the rotation direction of the drilling tool, and chips generated in cutting is discharged through the chip discharging groove. Compared with the prior art, the drilling tool has the advantages of high processing precision, stable processing, low cost and the like.
Description
Technical field
The present invention relates to a kind of brill cutter, especially relate to a kind of brill cutter for the processing annular groove.
Background technology
At present step cutting pattern microwave pcb board adopts lbg or milling machine is positive and negative mills mostly, and the lbg time spent is long and cost is larger, and batch production is difficult to realize.Milling machine is positive and negative to be milled consuming time longlyer, and is subjected to the impacts such as milling machine flatness, main shaft running accuracy, also is difficult to realize volume production, and quality also can be affected.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of brill cutter for the processing annular groove for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of brill cutter for the processing annular groove, comprise handle of a knife and cutter head, described cutter head is located at the handle of a knife lower end, the sidewall of described cutter head offers chip area, this row belongs to groove edge and is provided with outer blade, the lower end of described cutter head offers cutting slot, the sidewall of this cutting slot is provided with interior blade, described outer blade is used for the lateral wall of processing annular groove, described interior blade is used for the madial wall of processing annular groove, outer blade and interior blade are along the direction of rotation cutting workpiece that bores cutter, and the chip that cutting produces is discharged by chip area.
Described cutting slot is the U-shaped groove.
Described chip area is circular groove.
Described cutter head is the cutter head that is provided with 30 °～70 ° of anglecs of rotation.
The length of described outer blade is 6～14mm, and the length of interior blade is 2～4mm.
Compared with prior art, the present invention has the following advantages:
1, machining accuracy is high: adopt this kind drill produced circular arc type step pcb board very high without burr, precision.
2, save cost: in use can be repeatedly used.Reduce Material Cost.
3, processing is stable: owing to adopting carbide alloy, material hardness and height.Adopt rig production controllability good.
4, be widely used: but Machining Arc, annulus to the PCB stepped plate, Rigid Flex all can make
