Problems solved by technology

[0002] At present, most microwave PCB boards with circular steps adopt laser slotting or milling machine front and back milling. Laser slotting takes a long time and costs a lot, and mass production is difficult to achieve.
The forward and reverse milling of the milling machine takes a long time, and is affected by the flatness of the milling machine and the rotation accuracy of the spindle, it is also difficult to achieve mass production, and the quality will also be affected

Embodiment

[0020] Such as figure 1 As shown, a drill bit for machining annular grooves includes a tool handle 1 and a cutter head with a rotation angle of 65°. 3. The flute 3 is U-shaped, with an outer blade 2 on its edge, and a cutting groove 4 at the lower end of the cutter head. The cutting groove 4 is arc-shaped, and its side wall is provided with an inner blade 5 and an outer blade 2 It is used to process the outer wall of the annular groove, and the inner blade 5 is used to process the inner wall of the annular groove. The outer blade 2 and the inner blade 5 cut the workpiece along the rotation direction of the drill, and drill annular grooves of different depths according to the thickness of the workpiece. , and the chips generated by cutting are discharged from the chip flute 3.

[0021] The cutter head is made of hard alloy processed into particles, which has high hardness and precision. It can process PCB boards of different materials. It can be processed continuously for more...

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 [0001] The invention relates to a drill, in particular to a drill used for machining annular grooves. Background technique [0002] At present, most microwave PCB boards with circular steps adopt laser slotting or milling machine front and back milling. Laser slotting takes a long time and costs a lot, and mass production is difficult to achieve. The front and back milling of the milling machine takes a long time, and is affected by the flatness of the milling machine and the rotation accuracy of the spindle, it is also difficult to achieve mass production, and the quality will also be affected. Contents of the invention [0003] The object of the present invention is to provide a drill for machining annular grooves in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A drill bit for processing annular grooves, comprising a handl...
