Abstract

The utility model relates to a milling cutter, belongs to the technical field of machining cutting tools, and in particular relates to a cubic boron nitride (CBN)/polycrystalline diamond (PCD) deep-cavity end-cutting end milling cutter. A circumferential cutting edge of the end milling cutter comprises a main cutting edge and an auxiliary cutting edge. The main cutting edge is parallel with a center line of a cutter handle, an included angle between the auxiliary cutting edge and the main cutting edge is about -1degree, and the auxiliary cutting edge extends to an end cutting edge. The CBN/PCD deep-cavity end-cutting end milling cutter effectively resolves the problem of heavy grinding efficiency of a CBN/PCD cutting tool, reduces abrasion between the circumferential cutting edge of the cutting tool and laterals walls of a cavity, prolongs service life of the cutting tool, and simultaneously improves surface quality and production efficiency of processed work pieces.

Description

The dark chamber end-grain cutting of a kind of CBN/PCD slotting cutter
Technical field
The utility model relates to a kind of milling cutter, and the dark chamber end-grain cutting of especially a kind of CBN/PCD slotting cutter belongs to the machining tool technical field.
Background technology
The CBN/PCD milling cutter is common machining tool, in the prior art but often there is following problem in its design production: 1, and the efficient of refacing of cutter is generally not high; 2, the friction of cutter Zhou Ren and cavity lateral is serious, and the cutter working (machining) efficiency is low, thereby has influenced the service life of milling cutter integral body, has accelerated to change the frequency of cutter, has increased production cost; 3, the surface quality of work piece and production efficiency are subjected to very big influence.
Therefore, how to design a kind of novel milling cutter, become the technical barrier that those skilled in the art need to be resolved hurrily to overcome above-mentioned defective.
The utility model content
The utility model aims to provide the dark chamber end-grain cutting of a kind of CBN/PCD slotting cutter, it has overcome above-mentioned deficiency by special structure design, efficiently solve the efficiency of refacing of CBN/PCD cutter, and reduced the friction of cutter Zhou Ren and cavity lateral, improve cutter life, improved the surface quality and the production efficiency of work piece simultaneously.Its technical scheme that adopts is as follows:
The dark chamber end-grain cutting of this CBN/PCD slotting cutter comprises handle of a knife and is positioned at the blade of handle of a knife end, wherein, described blade includes cutter groove, Zhou Ren, transition arc and end sword, described end sword is positioned at the end of described cutter groove, described Zhou Ren is positioned at the top, side of described cutter groove, and described transition arc is formed at described Zhou Ren and end sword joint; Wherein said Zhou Ren is made of main cutting edge and front cutting edge, and described main cutting edge is parallel with the center line of handle of a knife, has angle between described front cutting edge and the main cutting edge, and extends to described end sword.
Preferably, described cutter groove is straight trough or helicla flute.
Preferably, described main cutting edge length is that 2mm is to 4mm.
Compared with prior art, the utlity model has following advantage:
This product efficiently solves the efficiency of refacing of CBN/PCD cutter by shortening main cutting edge length, and has reduced the friction of cutter Zhou Ren and cavity lateral, has improved cutter life, has improved the surface quality and the production efficiency of work piece simultaneously.

The right view of Fig. 2: Fig. 1.
Symbol description: 1, handle of a knife; 2, cutter groove; 3, main cutting edge; 4, front cutting edge; 5, transition arc; 6, end sword.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
An embodiment of the present utility model as shown in Figure 1, the dark chamber end-grain cutting of this CBN/PCD slotting cutter mainly comprises: handle of a knife 1 and the blade that is positioned at handle of a knife 1 end, wherein, blade includes cutter groove 2, Zhou Ren, transition arc 5 and end sword 6, end sword 6 is positioned at the end of cutter groove 2, Zhou Ren is positioned at the top, side of cutter groove 2, and transition arc 5 is formed at Zhou Ren and end sword 6 joints; Wherein Zhou Ren is made of main cutting edge 3 and front cutting edge 4, and main cutting edge 3 is parallel with the center line of handle of a knife 1, has angle (for about-1 °) between front cutting edge 4 and the main cutting edge 3, and extends to end sword 6.
Cutter groove 2 for example is straight trough or helicla flute.
Main cutting edge length for example is about 20% of tool diameter, and about 2mm is to 4mm.
The angle of front cutting edge for example is the length of reconditioning end sword 6 and the tan amount of all sword reconditioning qualities, has so both shortened main cutting edge length, can reface with fixing thinning technique length again.
Fig. 2 shows the right view of Fig. 1, the whole cutting edge shape of holding sword to become with all tooth shapes as can be seen.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
