1. in the machining process of the blade disc, the surface structure of the blade is complex, the axial direction of the cutter is constantly changed, the abrasion degree is large in the machining process of the ball cutter, and the machining service life is short;
2. the common ball cutter has poor chip removal capability, is easy to break and has low processing efficiency;
3. when the ball cutter processes the surface of the blade disc, the rebound amount of the blade disc surface to the ball cutter is increased, so that the contact area with the ball cutter is increased, and the processing precision is reduced.
Therefore, the cutter which can adapt to the complex working condition of the surface of the blade disc and has long service life is one of the necessary conditions in the blade disc machining.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the high-efficiency milling cutter for the heat-resistant alloy, which can change the height of an injection mold during maintenance in time according to the maintenance requirement.
In order to achieve the aim, the invention provides the following technical scheme that the heat-resistant alloy high-efficiency milling cutter comprises a cutter bar and is characterized in that: cutter arbor one end is formed with the tool bit, the tool bit is formed with central boss, has seted up cutting edge and chip groove, central boss and the central fixed connection of cutter arbor, central boss and the coaxial setting of cutter arbor, the cutting edge includes four at least, the cutting edge equipartition is in central boss side week and with central boss arranges for central circumference, the chip groove is seted up two between the cutting edge, cutting edge and chip groove use the same direction of spiral to extend to the cutter arbor side body, the cutting edge is even as an organic whole with the cutter arbor.
Further setting the following steps: the cutting edge surface is passivated and wet blasted.
Further setting the following steps: the cutting edge includes six.
Further setting the following steps: one end of the chip groove close to the central boss is connected with the central boss into a whole, and the other end of the chip groove is connected with the cutter bar into a whole.
Further setting the following steps: the adjacent surfaces of the six cutting edges are smooth curved surfaces.
Further setting the following steps: the top surface of the cutting edge is provided with a plurality of uniformly arranged grooves.
In summary, the invention has the following advantages: the problems that a conventional common ball cutter is easy to remove chips and break when a leaf disc is roughly machined, the service life is short, machining efficiency is low and the like are solved, the structure of a cutter head is optimized, the coating of a cutting edge of the cutting edge is optimized, the milling strength and the milling precision of the cutter are integrally improved, and the common ball cutter has the advantages of being high in chip removal performance, good in cutting edge cooling effect, long in machining service life and the like.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Embodiment 1, a high efficiency milling cutter of heat-resisting alloy includes the cutter arbor, its characterized in that: cutter arbor one end is formed with the tool bit, the tool bit is formed with central boss, has seted up cutting edge and chip groove, central boss and the central fixed connection of cutter arbor, central boss and the coaxial setting of cutter arbor, the cutting edge includes four at least, the cutting edge equipartition is in central boss side week and with central boss arranges for central circumference, the chip groove is seted up two between the cutting edge to central boss top is the base face, and every two cutting edges that use central boss axis symmetry are the S form on the base face, cutting edge and chip groove extend to the cutter arbor side body with same spiral direction, the cutting edge is even as an organic whole with the cutter arbor.
As shown in fig. 1 and 2, the cutting edge surface is subjected to the passivation and wet blasting treatment, and the cutting edge includes six.
As shown in fig. 1 and 2, one end of the chip groove close to the central boss is connected with the central boss into a whole, the other end of the chip groove is connected with the cutter bar into a whole, the adjacent surfaces of the six cutting edges are smooth curved surfaces, and the top surfaces of the cutting edges are provided with a plurality of uniformly arranged grooves.
In the rough machining process of a specific blade disc, the numerical control milling machine drives the cutter bar to rotate at a high speed, the cutter head part separately starts milling, resistance in the machining process of the cutter head can be reduced through 6 chip grooves in the form of the chip breaking grooves, the formation of large-volume scrap iron is avoided, scrap iron in the milling process can be discharged through the chip removing grooves, the cutting edges and the chip removing grooves extend spirally to the cutter bar, the chip removing capacity of the cutter head is further improved, the cutting strength of the cutting edges is improved, the cooling effect of each cutting edge when the cutting edges are milled alternately is improved, the milling strength of the cutter head is further improved through a plurality of grooves in the top of the cutting edges, and the cutter head can have high machining efficiency in the semi-finishing machining.
When the high-temperature alloy cutter is machined, if the cutter edge has fine-line edge breakage, rapid abrasion and large-block edge breakage can occur very quickly, passivation and wet sand blasting treatment can be performed at the position of the cutting edge, reasonable passivation can effectively remove the cutting edge sawteeth of the smooth cutter, the binding force of the coating is increased, the stress of the coating is reduced, the peeling risk of the coating is reduced, the wet sand blasting process can enable the front and rear cutter faces of the cutting edge to generate fine hollow points under a microscope, the binding force of the coating is further enhanced, and under the same cooling liquid condition, the cooling effect of the cutting edge can be better.
Thereby whole cutter has avoided conventional ordinary ball sword to produce the chip removal easily when the bladed disk rough machining and has broken the sword, and the life-span is short, machining efficiency low scheduling problem, starts with from tool bit configuration optimization, cutting edge coating optimization processing, has wholly improved the milling strength and the precision of cutter, has advantages such as the chip removal nature is strong, cutting edge cooling effect is good, processing life is long.
The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims.
