Implement in the case of a little details.Below the description of embodiment is used for the purpose of providing by showing the example of the utility model
The utility model is more fully understood.
Below in conjunction with attached drawing, the technical solution of the utility model embodiment is described.
Embodiment：
As shown in Figure 1, the brill milling compound tool in the present embodiment, including handle of a knife 1 and the cutter head 2 for being connected to 1 one end of handle of a knife,
Handle of a knife 1 and cutter head 2 are coaxial；Cutter head 2 includes drilling portion 3 and the chamfered section 4 being arranged between drilling portion 3 and handle of a knife 1, chamfered section 4
Including changeover portion 5 and be arranged 5 both ends of changeover portion be respectively used to aperture both ends end face carry out chamfer machining positive surface chamfer section 6
With reverse side chamfering section 7；The diameter of changeover portion 5 is less than 3 diameter of drilling portion, and the length of changeover portion 5 is not less than the depth in hole to be processed；
The cutting edge of positive surface chamfer section 6 is located at 1 end of handle of a knife, and the cutting edge of reverse side chamfering section 7 is located at 3 end of drilling portion.
Preferably, its axis direction of 2 upper edge of cutter head is provided at least one chip space；When drilling, clast is from chip space
Discharge, improves the working efficiency of cutter.
Preferably, chip space is symmetrically arranged two chip spaces；Symmetrically arranged two chip spaces improve chip removal
Efficiency.
Preferably, chip space is helical flute；When drilling, clast is discharged from the good helical flute of chip removal effect,
Improve the working efficiency of cutter.
Preferably, the surface roughness of the cutting edge of chamfered section 4 is not more than Ra0.4；When processing, surface roughness is little
Machining accuracy is can guarantee in the cutting edge of Ra0.4, and then meets processing request.
Preferably, the cutting edge surface of cutter head 2 is coated with film coating；Coating treatment reduces during tool sharpening
Friction and fever, improve cutting-tool's used life.
Preferably, drilling portion 3 is fluted drill structure, two to be mutually parallel in its end section are provided in fluted drill structure
Main cutting edge, the drill bit at fluted drill structure is designed as back taper structure, to reduce contact of its minor flank with hole wall；And it is numb
Flower bore structure at it is unbearable be designed as positive wimble structure, to ensure its rigidity.
Operation principle：In use, first by Cutting tool installation manner on lathe, start drilling processing, at this time cutter head drilling later
Workpiece to be processed is processed in two main cutting edge drillings in portion, and when processing, clast is discharged from helical flute.
After hole drills through, the changeover portion of chamfered section passes through processed hole, and the cutting edge of reverse side chamfering section is made to be located at aperture
The cutting edge in the outside of one end end face, positive surface chamfer section is close to aperture the other end face, at this time with the cutting edge of positive surface chamfer section
Positive surface chamfer is carried out to aperture the other end face.
It griffes after positive surface chamfer, then proceeds as follows：(1) make the axis runout workpiece to be processed of this cutter
Hole axial line certain distance e；(2) aim at tool operation is carried out after；(3) reverse side chamfering is proceeded by, that is, uses the anti-of reverse side chamfering section
Face main cutting edge takes a round around aperture end face；Repetitive operation (1)-(3) are until aperture end face reverse side chamfering is fully completed；Finally
Keep tool axis coaxial with axially bored line, griffes to complete processing tasks.
This cutter integrates drilling and chamfering function, ensure that the continuity of process, eliminates multiple cutters
It uses；Relative to traditional technique, which reduce tool change times and manufacturing procedure, substantially increase processing efficiency, reduce life
Produce cost；Meanwhile using the workpiece of this tool sharpening, because completing drilling and chamfering processing on same cutter, eliminates and change
Knife process, therefore the chamfering in the aperture and aperture both ends processed has higher concentricity, can meet the dress of precision parts
With requirement.
The utility model is not limited to examples detailed above, in claims limited range of the utility model, this
