Abstract
The utility model discloses a welded type CBN (cubic boron nitride) spiral end milling cutter, which comprises a cutter body, one cutter tooth to eight cutter teeth and CBN blades. Each cutter tooth is a spiral tooth, the angle of an oblique slot of the cutter body ranges from 5 degrees to 20 degrees, the rake angle ranges from negative 30 degrees to negative 15 degrees, the CBN blades are fixed into the oblique slot, and the spiral angle of the milling cuter ranges from 5 degrees to 20 degrees. The polycrystalline cubic boron nitride (CBN) blades are welded on the cutter body provided with the oblique slot, and a rake face of the cutting edge is arranged spirally by means of grinding. The spiral end milling cutter with a 15-degree spiral angle and a negative 25-degree rake angle is modified based on a polycrystalline cubic boron nitride (CBN) milling cutter, so that impact force is reduced and tipping is almost avoided when the spiral end milling cutter is used, and the service life of the milling cuter is prolonged.
Description
Technical field
The utility model relates to a kind of cutter of metal cutting manufacture field, relates in particular to welded type helical tooth CBN slotting cutter.
Background technology
In traditional metal cutting processing, the fine finishining of quench part mainly adopts grinding method to guarantee the dimensional accuracy of part.But the working position of some part can't grinding, can deform behind the parts quenching in addition, is difficult to guarantee without its dimensional accuracy of processing, needs this moment the employing milling to process.
Polycrystalline cubic boron nitride (CBN) is that hardness is only second to adamantine material, and its processing characteristics is superior to diamond again, can be used for quench part and mills generation mill processing, and in addition, working (machining) efficiency is higher than the efficient of grinding.
Milling Process belongs to interrupted cut, and the straight-tooth slotting cutter is in milling process, and whole blade is cut simultaneously and cut out, and the impulsive force that slotting cutter receives is big, is prone to produce vibration, and machined surface fineness is bad.If can the slotting cutter blade be made helical tooth, make it in milling, cutter tooth is cut gradually and is cut out, and working angles is steady, and machined surface fineness is good, and the durability of cutter is high.
At present, the polycrystalline cubic boron nitride milling cutter all adopts straight-tooth, does not have spiral-distributed CBN blade.
The utility model content
The utility model is made the helical tooth form with the polycrystalline cubic boron nitride milling cutter, thereby realizes the effective Milling Process to materials such as hardened steel.
The utility model is achieved in that
Welded type CBN helical end mills comprises: cutter hub, cutter tooth, said cutter tooth are 1～8 helical tooth, and the angle of bevel of said cutter hub is 5 °～20 °, and anterior angle is-30 °～-15 °; Comprise that also the CBN blade is fixed in the said skewed slot, the helical angle of milling cutter is 5 °～20 °, and anterior angle is-30 °～-15 °.
Be welded to polycrystalline cubic boron nitride (CBN) blade on the cutter hub with skewed slot, make the blade rake face have the helical arrangement form through grinding.
The utility model is made helical end mills with polycrystalline cubic boron nitride (CBN) milling cutter, and its helical angle is 15 °, and anterior angle is-25 °.Impulsive force reduces during use, and the tipping situation is rare, and prolong the service life of milling cutter.
