Abstract

The utility model discloses a combined reaming and milling cutter. The combined reaming and milling cutter comprises a cutter rod and a cutter head, wherein the front end of the cutter head is conical, a first stepped cutting edge, a second stepped cutting edge and an end surface cutting edge are sequentially arranged in the middle of the cutter head annularly; a longitudinal cutting edge is arranged on each of the first stepped cutting edge and the second stepped cutting edge in the longitudinal direction; a transverse cutting edge is arranged on each of the first stepped cutting edge and the second stepped cutting edge in the transverse direction; and the longitudinal cutting edges of the first stepped cutting edge and the second stepped cutting edge are opposite to each other. According to the cutter, aperture dimension forming and milling of the bottom surface of the aperture are performed by using a single cutter, and machining of two different stations is finished; and in the milling process, a secondary workpiece centering procedure is eliminated, so that misoperation is avoided, the labor intensity of workers is reduced, the machining accuracy is improved, the production pace is accelerated, and the production cost is reduced.

Description

The combined type cutting reamer
Technical field
The utility model relates to the cutter field, especially relates to a kind of cutting reamer.
Background technology
Some parts to be processed have ladder class hole and local aperture annular groove, many cutter is processed adding to use successively man-hour, need in the processing with one aperture class reamer to be processed earlier, again with one milling cutter processing aperture bottom face or hole wall annular groove, and need the processing of secondary centering man-hour adding, this has reduced machining accuracy undoubtedly, also reduced production efficiency, increased cost simultaneously, increased working strength of workers, the steady quality of product has also been constituted influence.
The utility model content
The purpose of this utility model is to provide a kind of combined type cutting reamer, can time processing go out ladder class hole and local aperture annular groove.
The technical solution of the utility model is:
The combined type cutting reamer, comprise knife bar and cutter head, the cutter head front end is taper, the middle part hoop of cutter head is provided with first step cutting edge, second step cutting edge and face cutting edge successively, the longitudinal direction of first step cutting edge, second step cutting edge is equipped with the straight-cut sword, horizontal direction is equipped with the cross cutting sword, and the straight-cut sword of described first step cutting edge, second step cutting edge is for arranging in opposite directions face-to-face.
The cutting edge of described face cutting edge has the angle at obtuse angle.
Described angle is 120 degree-150 degree.
The bits that mill that the utility model has been finished aperture compact dimensions and bottom surface, aperture by a cutter are processed, and have finished two different stations.In milling the bits process, reduced by two subjob centerings, avoid taking place operate miss, alleviate labor strength, improved machining accuracy and productive temp simultaneously, reduced production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of X part among Fig. 1.
The specific embodiment
As shown in Figure 1, the utility model comprises knife bar 1 and cutter head 2.Cutter head 2 front ends are taper, and the middle part hoop is provided with first step cutting edge 3, second step cutting edge 4 and face cutting edge 5 successively.As shown in Figure 2, first step cutting edge 3, longitudinal direction have straight-cut sword 6, the horizontal direction of second step cutting edge 4 has cross cutting sword 7, and the straight-cut sword 6 of first step cutting edge 3, second step cutting edge 4 arranges face-to-face in opposite directions, can process step surface.Straight-cut sword 6 can machining hole the end face of radially aspect, and the axial end that cross cutting sword 7 can machining hole.Face cutting edge 5 can directly be processed the aperture bottom face that portals, and can directly process chamfering.Face cutting edge 5 has the angle at obtuse angle, gets 120 degree ~ 150 degree usually.
The material of knife bar 1 has enough rigidity for for carbide alloy YG.Each cutting edge of cutter head 2 is the polycrystalline diamond PCD of welding.Processing dimension is stable, precision height, high conformity.
During use, at first first step cutting edge 3, second step cutting edge 4 process step surface, by the program of setting tools lift is arrived certain position by the radial end face part of straight-cut sword 6 machined bottom of first step cutting edge 3, process end face by face cutting edge 5 then.A cutter is finished two stations that cutter is to be processed.
