Abstract
The utility model discloses a positive and negative dual-blade polycrystalline diamond boring cutter which comprises a cutter rod and cutter heads, wherein the cutter rod comprises a support rod at the rear part and two cutter head mounting base bodies positioned at the front end of the support rod; the two cutter head mounting base bodies are respectively provided with a cutting blade mounting surface; the positions of the two cutter head mounting surfaces are in central symmetry relative to the axis of the cutter rod; the two cutter heads are respectively welded on the two cutter head mounting surfaces; and the two cutter heads are respectively a cutter inlet cutter head and a cutter withdraw cutter head. According to the positive and negative dual-blade polycrystalline diamond boring cutter provided by the utility model, one-cutter-two-blade design is adopted to replace the original cutter with only one cutting blade, the machining efficiency is improved, and the cutter cost is lowered; a positive blade participates in cutting in cutter feeding for boring, the positive blade participates in cutting in cutter withdrawing, clamping once and machining twice are carried out, coarse boring and fine boring are carried out together, the machining time is saved, and the machining efficiency is improved; and chip breaker grooves are added on the cutter heads, which is good for chip removing, and the problem of scraping of the surface of the workpiece is solved effectively.
Description
Technical field
The utility model relates to the technical field of twolip boring cutter, particularly relates to a kind of positive and negative twolip polycrystalline diamond boring cutter.
Background technology
Boring cutter is cutter relatively more commonly used as the cutter of retrofit in field of machining; Existing boring cutter generally is the hilted broadsword sword, and a clamping cutter can only be accomplished the processing of an accuracy class, and its working (machining) efficiency is lower; Existing in addition cutter generally is to design to common iron and steel parts; Not too suitable during for processing aluminum workpiece, because the material pliability of aluminum workpiece is good, cutting swarf can not natural chip breaking; The phenomenon that occurs being wrapped on the cutter head through regular meeting takes place, and for the quality of machined surface very big influence is arranged.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of positive and negative twolip polycrystalline diamond boring cutter to be provided.
The technical scheme of the utility model is: a kind of positive and negative twolip polycrystalline diamond boring cutter; Contain knife bar and cutter head; Described knife bar comprises the support bar and two cutter heads installation matrixes that are positioned at the support bar front end at rear portion; Described two cutter heads are installed on the matrix and are respectively equipped with the blade installed surface, and the position of two cutter head installed surfaces is centrosymmetric about the axle center of knife bar, and described cutter head is two and is welded on respectively on two cutter head installed surfaces; Two cutter heads are respectively feed cutter head and withdrawing cutter head.
The point of a knife of described two cutter heads is the circular arc point of a knife, on its rake face, is equipped with the chip-breaker with the circular arc of point of a knife essentially concentric, and the cross section of this chip-breaker is L shaped, and this chip-breaker bottom surface and rake face have angle.
Described chip-breaker bottom surface and rake face have 4 °≤α of angle≤10 °.
Described chip-breaker outer edge is L1 to the distance between the blade, 0.1mm≤L1≤0.2mm.
Described knife bar afterbody is provided with the mounting platform with the cutter spindle line parallel.
The material of described knife bar is a carbide alloy, and the material of described cutter head is a polycrystalline diamond.
The beneficial effect of the utility model
The positive and negative twolip polycrystalline diamond boring cutter of the utility model adopts cutter two-edged design, substitutes original one having only a cutting edge on the cutter, improves working (machining) efficiency, reduces the cost of charp tool.Positive sword is participated in cutting in the feed bore hole, and anti-sword is participated in cutting in the time of withdrawing, twice processing of a clamping, and process time is practiced thrift in slightly single-minded boring, improves working (machining) efficiency.On cutter head, increase chip-breaker, be beneficial to chip removal, efficiently solve surface of the work and scratch problem.
