Description
Technical field
The utility model relates to cutter fields, and in particular to a kind of knife end sword dextrorotation right cut, the left-handed right cut side set of side edge
Milling cutter.
Background technique
The bottom and side wall of product to be processed needs simultaneous processing, and at present using the cutter for being dextrorotation right cut, dextrorotation right cut was both
Processable product bottom again can simultaneous processing product side wall.But because of this mode, chip removal side when the tool sharpening of dextrorotation right cut
To upward, when easily leading to converted products side wall, chip removal, which is not cut off, there is burr and turns over and stay in product surface.
Guarantee converted products side wall impulse- free robustness, cutter rotation direction should be designed as left-handed right cut (left-handed right cut：Cutter rotation direction to
A left side, chip removal direction is downward when processing, opposite with dextrorotation right cut chip removal), when this rotation direction chip removal can inhibit downwards converted products side wall
Burr, which is pushed, stays in product surface without turning over.
But the cutter front end end sword backlash part of left-handed right cut is negative rake (cutter front end is without cutting force), leads to product bottom
Portion can not process (can only converted products side wall).
A kind of left-hand circular polarization of Patent No. CN201621460167.7, including knife handle and cutter hub, the rear end of the cutter hub
It is connected with the front end of knife handle, it is characterised in that：The cutter hub length is 2 times of shank length, and cutter hub and knife handle are cylinder
Shape structure, cutter hub and knife handle are coaxial, and cutter hub maximum gauge is equal to shank diameter, and the outer surface of cutter hub is provided with Nano diamond guarantor
Sheath, the outer surface of Nano diamond protective layer are provided with antirust oil reservoir, and the cutter hub constitutes as follows：Left-handed blade, left-handed row
Consider slot, peripheral edge and chisel edge to be worth doing；Wherein, left-handed blade is located on the side wall of cutter hub, the angle of left-handed blade and cutter hub central axis
It is 45 °, the vertical range of two neighboring left-handed blade is 1-3mm, and left-handed chip space is between two neighboring left-handed blade, 6
A peripheral edge is evenly arranged in the front end of cutter hub, and the rear end of peripheral edge is connected with the front end of left-handed blade, and chisel edge is located at peripheral edge
Between.
Still above-mentioned defect is not made up.
Summary of the invention
The embodiments of the present invention there is provided a kind of knife end sword dextrorotation right cut, the left-handed right cut staggered tooth milling cutter of side edge,
Cutter front end, which is effectively guaranteed, has cutting force that product bottom can be processed, but when having taken into account converted products side wall chip removal downwards, hair
Thorn pushes, and turns over without will cause burr and stays in product surface.Solve the problems, such as that burr occurs in converted products.
