Abstract
The utility model provides a forming end mill which can process a hole with an inner wall with a special structure, and improves the processing precision and the concentricity. The forming end mill comprises a tool shank and a tool bit arranged on one end of the tool shank, wherein the tool bit comprises a main cutting edge arranged at the axial end and a guiding part of spiral grooves formed around the tool bit in the circumferential direction. The forming end mill is characterized in that tool faces-tool teeth are formed at the tops of the walls of the spiral grooves; continuously-distributed notches are formed on the tool faces of the tool faces-tool teeth, and positioned in the initial position of a joint of the tool faces-tool teeth and the main cutting edge. The utility model has the benefits that the circular arc-shaped notches are formed on the tool faces of the tool faces-tool teeth, and bulges, which are identical to the notches in shape, are formed on the wall of a hole processed through milling, so that the drilling and milling of holes with special functions can be met. Compared with the conventional stepped manufacturing process, the processing efficiency and the concentricity of the hole can be improved.
Description
Technical field
The utility model relates to a kind of milling cutter, especially a kind of moulding slotting cutter.
Background technology
The technology of machining endoporus generally adopts technologies such as brill, boring, hinge, has the hole of specific demand to process to certain in the traditional handicraft, then need manyly cooperate cutter.When particularly need have design feature such as corrugated or dentation, the hole inwall is carried out secondary operations with regard to needing cutters such as special boring cutter or reamer to the inwall in certain hole.So not only can not raise the efficiency, and maybe be because tool setting is inaccurate and concentricity that cause is bad during secondary operations, the situation that makes processed hole scrap occurs.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of can process the hole that inwall is a special construction, and the moulding slotting cutter that improves working (machining) efficiency and concentricity.
The utility model solves the technical scheme that its technical problem adopted: a kind of moulding slotting cutter; Comprise handle of a knife and be located at the cutter head of handle of a knife one end; Cutter head includes the main cutting edge of axial end setting and around cutter head the spiral fluted targeting part is set circumferentially; It is characterized in that: said helicla flute cell wall top is sword face cutter tooth, all offers the breach of continuous distributed on the sword face of this sword face cutter tooth, and this breach is from the initial setting of the joint of sword face cutter tooth and main cutting edge.
Further being set to of the utility model: said notch geometry is circular-arc.
Further being set to of the utility model: helicla flute is three on the said cutter head, and sword face cutter tooth is a similar number.
The beneficial effect of the utility model is: said helicla flute cell wall top is a sword face cutter tooth, then can carry out milling to the hole wall in processed hole, improves the fineness and the precision of hole wall.And on the sword face of sword face cutter tooth, offer circular-arc breach, pass through Milling Process so after, then make to occur and the corresponding to convexity of set notch geometry on the hole wall in processed hole, can satisfy some brills like this and mill with specific function hole.And the technology of distribute making with respect to tradition, the utility model can improve working (machining) efficiency and the concentricity to the hole.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the sketch map of the utility model embodiment.
Fig. 2 is that the A of Fig. 1 is to view.。
Fig. 3 is the partial schematic diagram in the processed hole of the utility model embodiment.
The specific embodiment
Shown in Fig. 1-3; Present embodiment comprises handle of a knife 1 and is located at the cutter head 2 of handle of a knife 1 one ends; Cutter head 2 includes the main cutting edge 21 of axial end setting and around cutter head 2 targeting part of helicla flute 22 is set circumferentially, and said helicla flute 22 cell wall tops are sword face cutter tooth 221, all offer the circular-arc breach 2211 of continuous distributed on the sword face of this sword face cutter tooth 221; This breach 2211 is from the sword face cutter tooth 221 initial setting of joint with main cutting edge 21, and extends on the sword face cutter tooth 221 always.In the utility model, breach 2211 also may extend to the other end of sword face cutter tooth 221.Wherein, helicla flute 22 is three on the said cutter head, and sword face cutter tooth 221 is a similar number.The hole interior wall construction that the utility model processed is as shown in Figure 3.
In the utility model, said helicla flute 22 cell wall tops are sword face cutter tooth 221, then can carry out milling to the hole wall in processed hole, improve the fineness and the precision of hole wall.And on the sword face of sword face cutter tooth 221, offer circular-arc breach 2211, pass through Milling Process so after, then make to occur and the corresponding to convexity of set breach 2211 shapes on the hole wall in processed hole, can satisfy some brills like this and mill with specific function hole.And the technology of distribute making with respect to tradition, the utility model can improve working (machining) efficiency and the concentricity to the hole.The utility model can also have other embodiments, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of the utility model requirement protection.
