Abstract
The utility model relates to a kind of Whole PC BN blade, and blade rake face is provided with curved surface groove, and the shape of curved surface groove matches with blade shapes.The utility model, owing to having designed curved surface groove on blade, has carried out forced chip-cutting to the smear metal in production process, has reduced the probability that blade heel and toe wear damages, and has stock-removing efficiency high, long service life, machining accuracy advantages of higher.
Description
Technical field
The utility model relates to a kind of machining tool, especially relates to band chip-breaker PCBN blade for a kind of roughing.
Background technology
PCBN (polycrystalline cubic boron nitride) is that after being mixed with a small amount of binding agent by CBN micro mist, under high-temperature and high-pressure conditions, artificial synthetic a kind of cutter material that is best suited at present High-speed machining Ferrious material, has very high hardness, is difficult to shape.For a long time, can only be processed to without the dull and stereotyped cutter of flute profile always and be widely used in the processing of the difficult-to-machine materials such as hardened steel, high-speed steel, high-alloy wear-resisting casting iron surface spraying weld material.
In the continuous turning such as existing hardened steel, high-speed steel; because being cut properties of materials; in processing, there will be continuous chip; due to effectively chip breaking; smear metal often can be wrapped on cutter, knife bar and workpiece, thereby causes that surface of the work scratches, and reduces workpiece surface roughness; even can break cutting edge roundness, damage cutter.
Summary of the invention
Smear metal that the technical problems to be solved in the utility model occurs while being the materials such as current PCBN tool sharpening hardened steel is wound around the problem of cutter, knife bar and workpiece, for addressing the above problem, provides that a kind of stock-removing efficiency is high, Whole PC BN blade that can forced chip-cutting.
The purpose of this utility model realizes in the following manner:
A Whole PC BN blade, described blade is overall structure, and the rake face of blade is provided with curved surface groove, and the shape of curved surface groove matches with blade shapes.
The curved surface groove of described curved surface groove for being formed by laser engraving.
The groove depth of described curved surface groove is 0.05mm~0.5mm.
Closer, the groove depth of described curved surface groove is 0.05mm ~ 0.1mm or 0.1mm ~ 0.2mm or 0.2mm ~ 0.3mm or 0.3mm ~ 0.4mm or 0.4mm ~ 0.5mm.
The longitudinal breaking facial contour of described curved surface groove is trapezoidal.
The beneficial effects of the utility model are: owing to having designed curved surface groove on blade, smear metal in production process has been carried out to forced chip-cutting, therefore continuous chip is wound around the generation of the situations such as blade, knife bar and workpiece in controlled working completely, also can reduce the probability that cutter heel and toe wear damages simultaneously, extend the service life of cutter.
The utility model blade is applicable to the processing of the materials such as hardened steel, high-speed steel.It is compared with common PCBN blade, and the utility model blade has that stock-removing efficiency is high, long service life, machining accuracy advantages of higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the longitudinal partial cutaway schematic of Fig. 1 curved surface groove;
Fig. 3 is the structural representation of the another kind of embodiment of the utility model;
Fig. 4 is Fig. 3 generalized section.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model is a kind of Whole PC BN blade, described blade is overall structure, the rake face of blade is provided with curved surface groove, the shape of curved surface groove matches with blade shapes, is illustrated in figure 1 T-shaped blade in iso standard, T-shaped blade curved surface groove shapes be the V-arrangement curved surface groove that is arranged on three cutting ends of blade, be R type blade in iso standard as shown in Figure 3, Figure 4, the curved surface groove shapes of R type blade is annular.The curved surface groove of described curved surface groove for being formed by laser engraving.The groove depth of described curved surface groove is 0.05mm~0.5mm, can think 0.05mm ~ 0.1mm or 0.1mm ~ 0.2mm or 0.2mm ~ 0.3mm or 0.3mm ~ 0.4mm or 0.4mm ~ 0.5mm.。The longitudinal surface profile of curved surface groove is trapezoidal.
