Description
Technical field
The utility model belongs to cutting-tool engineering field, is related to a kind of cutter for machining more particularly to a kind of essence
Reamer.
Background technique
In machining, bottoming reamer is a kind of common hole finishing tool.Currently, existing bottoming reamer, often
Come with some shortcomings a little: 1, blade is prone to wear, and entire cutting-tool's used life is short；2, the finish in the hole processed is poor；3,
The verticality in hole is poor.For this purpose, it is necessary to designing a kind of bottoming reamer, to solve the above technical problems.
Utility model content
The purpose of the utility model is to provide a kind of long service life, the finish in hole and the good bottoming reamers of verticality.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of bottoming reamer, including cutter hub,
One end of the cutter hub is equipped with knife handle, and the other end is equipped with the cutter head of circular in cross-section, along the circle of the cutter head on the cutter head
Circumferential direction is evenly provided with six cutters tooth, is equipped with chip space on the cutter head between two neighboring cutter tooth, the chip space
Cross section is V-shaped, and the side of the cutter tooth is equipped with fixed bit, is fixed with carbide cutter tool at the fixed bit on the cutter tooth
The angle c that the side of piece, the side of the carbide chip and the chip space is formed is 60 °, the carbide chip
Side stretch out the periphery of the cutter head, the protruding side of the carbide chip is equipped with the first chamfering and the second chamfering, institute
The angle a for stating the first chamfering is 5 °, and the angle b of the second chamfering is 15 °, and alternate two carbide cutter tool on pieces are inlaid with
CBN blade, the CBN blade are 40mm, the CBN close to the front end of the carbide chip, the length of the CBN blade
One end of blade is 5mm with the front end distance L of the carbide chip.
Further, the chip space extends to the cutter hub.
Further, the knife handle is tapered, and taper is Mohs 4.
Further, one end of the knife handle is equipped with centre bore.
The utility model the utility model has the advantages that the utility model bottoming reamer, carbide cutter tool on piece be equipped with CBN blade, and
CBN blade is close to the front end of carbide chip, since CBN blade has high rigidity, good wearability and heat-staple spy
Point, therefore the hole finish that the bottoming reamer processes is very good, reaches mirror effect, the verticality precision in hole is high, and cutter makes
It is also grown with the service life；CBN blade is inlayed on alternate cutter tooth, while keeping the processing effect of cutter, reduces cutter manufacture
Cost；The protruding side of carbide chip is machined with the first chamfering and the second chamfering, the angle of the first chamfering, the second chamfering respectively
Angle be sequentially increased, reduce the processing resistance of cutter, and then reduce friction, improve the machining accuracy of cutter.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the bottoming reamer of the utility model embodiment.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the enlarged view of A in Fig. 1.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, the bottoming reamer of the present embodiment, the bottoming reamer include cutter hub 2.One end of cutter hub 2, which is machined with, is in
The knife handle 1 of taper, taper are Mohs 4, and one end of knife handle 1 is machined with centre bore 11.The other end of cutter hub 2 is machined with cross section
Rounded cutter head 3, the circumferencial direction on cutter head 3 along cutter head 3 are equably processed there are six cutter tooth 31, two neighboring on cutter head 3
The V-shaped chip space 32 in cross section is machined between cutter tooth 31, chip space 32 extends to cutter hub 2.The side of cutter tooth 31 adds
Work has fixed bit, is fixed with carbide chip 4, the side of carbide chip 4 and chip space 32 on cutter tooth 31 at fixed bit
Side formed angle c be 60 °.The periphery of cutter head 3 is stretched out in the side of carbide chip 4, and carbide chip 4 is stretched
