Abstract
The utility model relates to a polycrystalline diamond slot cutter, which comprises a cutter body and a cutter head connected to the front end of the cutter body, wherein the cutter body comprises a cutter handle part made of common carbon steel and a cutter bar part made of hard alloy, and the cutter handle part and the cutter bar part are fixedly connected together; and the cutter head is a polycrystalline diamond blade and is welded at the front end of the cutter bar. According to the polycrystalline diamond slot cutter, a base which is welded with a hard alloy block and made of 45 hardened and tempered steel is adopted, the strength of the cutter is improved, the defect of low strength of a cutter integrally made of common steel is overcome, and the service life of the cutter is prolonged. Meanwhile, the cost investment of the cutter integrally made of hard alloy is also reduced.
Description
Technical field
The utility model relates to the technical field of machine tool, particularly relates to a kind of polycrystalline diamond groove cutter.
Background technology
The groove cutter uses commonplace in the processing of automobile engine parts, and existing groove cutter cutter cutter hub material is whole plain steel, and its intensity is lower, and service life is shorter, haves much room for improvement.
Summary of the invention
The purpose of the utility model is in order to address the above problem, a kind of polycrystalline diamond groove cutter to be provided.
The technical scheme of the utility model is: a kind of polycrystalline diamond groove cutter; Comprise cutter hub and the cutter head that is connected the cutter hub front end; Described cutter hub comprises the knife bar part of the shank portion and the carbide alloy of common straightcarbon steel; The two is fixed together, and said cutter head is the polycrystalline diamond blade, and the weldering knot is at the front end of knife bar.
The rake face of said polycrystalline diamond blade and the angle of horizontal plane are 9 °-11 °.
The main back knife face of said polycrystalline diamond cutter and the angle of vertical plane are 7 °-9 °.
The minor flank of said polycrystalline diamond cutter and the angle of vertical plane be 50 '-70 '.
The main back knife face of described carbide alloy knife bar and the angle of vertical plane are bigger than the angle of the main back knife face of polycrystalline diamond cutter and vertical plane.
The minor flank of described carbide alloy knife bar and the angle of vertical plane are bigger than the angle of the minor flank of polycrystalline diamond cutter and vertical plane.
[0010]The beneficial effect of the utility model
The polycrystalline diamond groove cutter of the utility model adopts the matrix of 45 quenched and tempered steel of welding hard alloy blocks, has improved the intensity of cutter, has remedied the whole low defective of cutter intensity of plain steel that is, improves cutter life.Reduced again simultaneously and the cost input that adopts the whole hard alloy cutter hub.
