Abstract
The utility model discloses a polycrystalline cubic boron nitride tool used for milling machining. The polycrystalline cubic boron nitride tool comprises blades and a tool body, wherein the periphery of one end of the tool body is provided with at least two blades at intervals, and the middle of the tool body is provided with a clamping hole. The polycrystalline cubic boron nitride tool is simple in structure, low in production cost, high in machining efficiency, and high in intensity during a milling process, can alleviate impact and vibration during a machining process, and can effectively avoid tipping and tool shatter. The blades which are four in number are uniformly installed on the periphery of one end of the tool body at intervals, an integral blade is replaced with the four blades which are distributed uniformly, blade materials are saved, and production cost is reduced. Because the four blades can be interchanged to take part in cutting, tipping or shatter of one blade does not affect use of other blades, machining efficiency can be improved, service life of the polycrystalline cubic boron nitride tool is prolonged, and utilization rate of the blade materials is improved.
Description
Technical field
The utility model belongs to the Machining Technology for Cutting field, particularly a kind of polycrystalline cubic boron nitride cutter that is used for Milling Process.
Background technology
The polycrystalline cubic boron nitride cutter that Milling Process is used comprises blade and cutter hub two parts, and the material of blade is polycrystalline cubic boron nitride (PCBN), and the material of cutter hub is a carbide alloy.
At present, blade is a monoblock type, and it is weldingly fixed on the carbide alloy cutter hub, because the hardness of polycrystalline cubic boron nitride is high, the clamping hole difficulty of processing in the middle of the blade is big, and working (machining) efficiency is low.In addition, polycrystalline cubic boron nitride covers the cutter hub holostrome, and the blade production cost is high, because polycrystalline cubic boron nitride can not all be participated in cutting, causes the polycrystalline cubic boron nitride utilization rate low, and waste of material is serious, and use cost is high.
The utility model content
The utility model provide a kind of simple in structure, production cost is low, working (machining) efficiency is high and can effectively avoid the cutter tipping and the cracked polycrystalline cubic boron nitride cutter that is used for Milling Process.
For realizing above-mentioned purpose, the technical scheme of the utility model is: a kind of polycrystalline cubic boron nitride cutter that is used for Milling Process, comprise blade and cutter hub, and be intervally distributed with the two-edged blade at least on the said cutter hub one end circumference, the cutter hub middle part is provided with the clamping hole.
Said blade is four swords, and evenly is distributed on the cutter hub one end circumference.
Said blade comprises blade and matrix, and blade is bonded on the matrix.
Said clamping hole comprises the two sections diameter shoulder holes at two ends and the circular hole at middle part, and two sections diameter shoulder holes are connected by the circular hole transition.
Cutter relief angle on the said cutter hub is 6 °～10 °.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises blade and cutter hub, is intervally distributed with the two-edged blade at least on the said cutter hub one end circumference, and the cutter hub middle part is provided with the clamping hole; It is simple in structure; Production cost is low, and working (machining) efficiency is high, in working angles, has higher intensity; Can alleviate the impact and the vibrations that occur in the process, can effectively avoid tipping and cutter cracked.
2, blade is four swords; And evenly be distributed on the cutter hub one end circumference; Change the four angle of throat sheets that are uniformly distributed with into by the monoblock type blade, both can save blade material, reduce production costs, participate in cutting because four angle of throat sheets can exchange; One angle of throat sheet tipping or the cracked use that does not influence other blades can improve working (machining) efficiency, prolong cutter life and blade material utilization rate.
3, the clamping hole comprises the two sections diameter shoulder holes at two ends and the circular hole at middle part, and two sections diameter shoulder holes are connected by the circular hole transition, can strengthen the applying degree of clamping hole and screw, and raising is the clamping ability fixedly.
4, the cutter relief angle on the cutter hub is 6 °～10 °, to adapt to the shape of milling workpiece, guarantees cutter hub and workpiece mutually noninterfere in the milling process.
5, in the utility model; Because the polycrystalline cubic boron nitride blade has high rigidity, high thermal stability, high manufacturing accuracy; Be suitable for processing exceptional hardness, unmanageable workpiece, carbide alloy cutter hub intensity is good, weldability can be good, thereby can improve the cutting ability of cutter.
Description of drawings
