Drawings

Fig. 1 is a schematic structural diagram of the PCD wire-drawing milling cutter of the present invention.

In the figure: 1. a knife handle; 2. a cutter head; 3. cutter teeth; 4. a chip groove; 5. a platform; 6. a chip removal surface.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, a PCD wire drawing milling cutter comprises a cutter handle 1, a cutter head 2, cutter teeth 3 and a chip discharge groove 4, the front end of the cutter handle 1 is provided with a plurality of platforms 5 which are arranged in an equiangular circumference, the cutter head 2 is welded and fixed on the platforms 5, the chip discharge groove 4 is arranged at the root of the platforms 5, and an included angle theta between two side walls of the chip discharge groove 4 is an acute angle larger than 60 degrees so that chips can be smoothly discharged.

When a large amount of chip removal needs are met, the chip removal surface 6 which is 90 degrees to the platform 5 is arranged at the front end of the knife handle 1, and the platform 5 and the chip removal surface 6 form a chip containing space so as to expand the chip removal space.

The cutter teeth 3 are formed on the cutting part of the cutter head 2, the cutter head 2 is a linear sheet cutter head, the cutter teeth 3 are also linear, the extending directions of the cutter head 2 and the cutter teeth 3 are parallel to the axis of the cutter handle 1, the cutter teeth 3 exceed the platform 5, so that the surface of a workpiece can be cut in the rotating process, the cutter teeth 3 are in a saw-tooth shape, the depth of the saw teeth is gradually deepened from the outer end 3-1 to the inner end 3-2, and the chip discharge grooves 4 are formed according to the cutter heads.

The front end of the tool holder 1 is arranged to be in a ball head shape, the outer end 2-1 of the tool bit 2 is correspondingly arranged to be in an arc shape, and the blade part of the arc section of the tool bit 2 is an arc smooth blade so as to be capable of being attached to a processing structure of a workpiece.

In other embodiments, the depth of the cutter teeth can be consistent, and when wire drawing effects with different depths need to be processed, the cutter head or the cutter is switched; the extending direction of the cutter head can also form a certain included angle with the axis of the cutter handle, so that the cutting effect is improved.

The cutter head 2 is a polycrystalline diamond cutter head, comprises a hard alloy substrate and a polycrystalline diamond material layer coated on the surface of the hard alloy substrate, has better performance, and can improve the performance and the service life of the milling cutter.

The technical principle is as follows:

when processing carbon fiber material, mainly used processing cavity structures through the effect of the sawtooth structure on the periphery, breaks the carbon fiber silk, improves the sharpness of cutter, promotes machining efficiency.

When the PCD wire-drawing milling cutter is used, the PCD wire-drawing milling cutter is suitable for being used as a vertical milling type, mostly adopts external diameter cutting, and is driven to rotate at a high speed through machine tool spindles such as CNC and the like to do mechanical relative motion with the surface of a workpiece so as to cut off redundant materials outside the surface size of the workpiece, and a wire-drawing effect is formed on the surface of the workpiece.

Many be used for processing like cell-phone center, button, notebook center etc. small area's lateral part structure, when the wire drawing effect that needs the difference, through change sword tooth profile shape to reach different wire drawing effects, this cutter should carry out the finish machining cutting, avoids directly carrying on the cutter blade that leads to when the jumbo size grinding is got rid of and produces easily and cave in mouth, wearing and tearing scheduling problem.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
