Abstract
The utility model relates to a tool for processing end surface grooves in a numerical control machine tool, in particular to a tool for processing ring end surface grooves. The tool is used for processing a ring end surface groove which has the max outside diameter Pi of less than 10 mm, the width of 1.5 to 2 mm and the depth of 15 to 20 mm. In the prior art, only larger, wider and shallower end surface grooves can be processed on a lathe, and ring end surface grooves which have the max outside diameter Pi of less than 10 mm cannot be processed. The tool comprises symmetrical cutting teeth, a tool body and a tool holder; inner and outer cutting edges are parallel and coaxial to the tool body and the tool holder, end cutting edges are perpendicular to the tool body and the tool holder; the integral structure is cylindrical; the diameter of the outer cutting edge is 0.5 mm larger than that of the tool body; the diameter of the inner knife edge is 0.5 mm smaller than that of a middle hole of the tool body. The symmetric cutting teeth, the tool body and the tool holder adopt an integral structure, single edge cutting is replaced with double edge cutting, the cutting strength of the cutting edge is enhanced, the chip discharge is facilitated, the processing efficiency is improved greatly, the processing method can be realized, and the ring end surface grooves can be processed in the numerical control lathe.
Description
Technical field
The utility model relates to for end face groove manufacture field, specifically a kind of cutter for the processing of annular end face groove.
Background technology
Because turning machine during compared with large end face groove, need to first cut out at end face the end face groove that a circle is shallow with cutting knife in processing, then left and right cross cutting is to Rack, then to incision shallow slot left and right cross cutting again, moves in circles to ultimate depth and groove width.So processing, need first cutting knife one side edge to be ground to larger relief angle, and larger relief angle can reduce the intensity of cutting knife, affects working (machining) efficiency.Example: process a maximum outside diameter ￠ 100mm, wide is 5mm, is the end face groove between 10mm deeply, and cutting knife one angle, rear flank must be greater than 11.8 degree; And a maximum outside diameter ￠ 50mm of processing, wide is 5mm, dark is the end face groove between 10mm, cutting knife one angle, rear flank must be greater than 18.4 degree, tool sharpening strength decreased now, starts to affect working (machining) efficiency, if again dwindle end face groove maximum outside diameter and width, cutter cannot sharpening, and processing cannot be carried out.
Summary of the invention
The technical solution adopted in the utility model is: be made up of symmetrical cutting teeth 1, cutter hub 2 and handle of a knife 3; Uniform two the tilting screw grooves of symmetrical cutting teeth 1, helicla flute 180 degree are symmetrical, there are two end face main cutting edges on helicla flute top, and vertical with handle of a knife 3 axis with cutter hub 2, outer blade diameter is greater than cutter hub diameter 0.5mm, and interior blade diameter is less than cutter hub interstitial hole diameter 0.5mm parallel with handle of a knife 3 axis with cutter hub 2.
Described symmetrical cutting teeth 1, cutter hub 2, handle of a knife 3 are overall column type structure.
The utility model has the advantages that: cutter global design is symmetrical cutting teeth, cutter hub, handle of a knife integral structure, material selection high-speed steel.The cutting edge that high-speed steel sharpening goes out is sharper than carbide cutter tool, in working angles, can bear larger cutting force and impact load; Intensity and resistance to overturning when symmetrical cutting teeth, cutter hub, handle of a knife integral structure increase tool sharpening; Intermediate throughholes plays good Self-centering Action in process; Article two, the symmetrical tilting screw groove of 180 degree, is convenient to row and cuts and cut with depositing.This cutter is with simplicity of design, rational in infrastructure, process reliable and stable, financial cost is low, promotes the use of at workshop numerically controlled lathe, working (machining) efficiency obviously promotes.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the front view of annular end face groove cutter in the utility model;
Fig. 2 is the side view of annular end face groove cutter in the utility model;
In figure: 1. symmetrical bidentate cutting edge, 2. cutter hub, 3. handle of a knife.
Detailed description of the invention:
Known from Fig. 1～2, annular end face groove cutter is by 1. symmetrical cutting teeths, 2. cutter hub, 3. shank portion composition.On symmetrical cutting teeth 1, uniform two the 180 symmetrical tilting screw grooves of degree, two end face main cutting edges and cutter hub, handle of a knife axis are vertical.
As shown in Figure 3: add man-hour by handle of a knife (3) installation and numerically controlled lathe drill point cover, tool axis is overlapped with axis of workpiece, use numerically controlled lathe depth drill circulation G74 to process.(G74R25；G74Z-20Q1.5F0.2。Depth drill loop parameter is set as: each machining-1.5mm, cutter all exits workpiece Z item zero surface row and cuts, and so moves in circles and is machined to ultimate depth.)
Obviously, above-described embodiment of the present utility model is only for example of the present invention is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description the variation of other different size specification.In the time that cutter is made, only need change the diameter of D1, D2, can realize the processing of different in width end face groove.Here cannot give exhaustive to all embodiments.Everyly belong to apparent variation or the still row in protection domain of the present utility model of variation that the technical solution of the utility model extends out.
Claims (2)
1. for a cutter for annular end face groove processing, it is characterized in that: formed by symmetrical cutting teeth (1), cutter hub (2) and handle of a knife (3); Uniform two the tilting screw grooves of symmetrical cutting teeth (1), helicla flute 180 degree are symmetrical, there are two end face main cutting edges on helicla flute top, and vertical with handle of a knife (3) axis with cutter hub (2), outer blade diameter is greater than cutter hub diameter (2) 0.5mm, and interior blade diameter is less than cutter hub interstitial hole diameter 0.5mm parallel with handle of a knife (3) axis with cutter hub (2).
2. a kind of cutter for the processing of annular end face groove according to claim 1, is characterized in that: described symmetrical cutting teeth (1), cutter hub (2), handle of a knife (3) are overall column type structure.
