The cutter body material is carbide, and the tool tip material is the diamond, and tool orthogonal rake ang2 is 5~7, and nose angle ang6 is 76~81, and tool cutting edge angle kr is 93~95, and auxiliary angle kr1 is 6~9, primary clearance ang1 and is 7~10, and front clearance ang5 is 14, and cutting edge inclination ang4 is 8, knife tip fillet R0.1mm~0.3mm. Adopt the utility model discloses a tool orthogonal rake ang2 is 5~7 can strengthen cutter bending strength and toughness, improves sharp degree, effectively reduces smear metal grinding resistance, and then reduces the deformation that the cutting heat arouses, the design of primary clearance can effectively reduce the hou mian wearing and tearing of cutter, improves cutter life, tool cutting edge angle kr is 93~95 can effectively reduce the resistance to cutting, cutting edge effective length and nose angle increase, and the heat dissipation condition of cutter further improves.
Description
Technical field
The utility model relates to machine cut cutter field, particularly a kind of cutting tool for boring for aluminum-base silicon carbide material aperture.
Background technology
In machining of metals, aluminum matrix composite is the competitively novel metal based composites of development of country faster of development in science and technology in the last few years. Carborundum (SiC) pellet hardness in carborundum (SiCp/Al content 20%～60%) aluminum matrix composite is about Hv2700. And the content of SiC particle is higher, material will more firmly and become fragile, and the difficulty of processing can increase. Be easy to make alloy matrix aluminum local melting with general traditional machining process, generate built-up edge, and make tool wear rust, cause surface roughness to decline, corresponding form and position tolerance is also just difficult to ensure. Particularly in aperture processing, general tool wear is serious, it is second-rate that durability is difficult to guarantee and hole precision and aperture, easily produce and collapse the defective effect such as limit and burr Product Precision, and the following precision welding diamond of Φ 6mm boring cutter is made associated tight with handle of a knife material, diamond, cutting-tool angle. Cutter structure and cutting-tool angle schematic diagram are as shown in Figure 1 and Figure 2. The application of the multiple material of metal current base is increasingly extensive, and a difficult problem for this type of aperture processing in the urgent need to address, improves the quality of products and working (machining) efficiency, further reduces costs. The utility model has solved the processing of aluminum-base silicon carbide material Φ 3mm～Φ 6mm hole, has realized the preparation of the little spot facing cutter of aluminum-base silicon carbide composite.
Utility model content
The utility model, mainly for the problem to existence in the processing of aluminum-base silicon carbide composite aperture in background technology, provides a kind of and is applicable to this material special boring cutter as shown in Figure 1, comprises cutter head 1, cutter hub 2, smooth transition district 3. To realize aperture high accuracy processing within the scope of Φ 3mm～Φ 6mm, and stock-removing efficiency and cutter life all effectively improve.
The technical solution of the utility model is: cutter hub material is carbide alloy, tool tip material is diamond, tool orthogonal rake Ang2 is 5 °～7 °, nose angle Ang6 is 76 °～81 °, and tool cutting edge angle Kr is 93 °～95 °, and auxiliary angle Kr1 is 6 °～9 °, primary clearance Ang1 is 7 °～10 °, front clearance Ang5 is 14 °, and cutting edge inclination Ang4 is 8 °, point of a knife fillet R0.1mm～0.3mm.
Further improvement of the utility model, tapering smooth transition between described cutter handle of a knife and cutter head, improves cutter integral rigidity, and improves boring cutter structural behaviour.
Improve as another step of the present utility model, described cutter is fixed cutter head by welding manner, realizes being synchronized with the movement of cutter head and cutter hub, prevents that cutter head is in the lower mismachining tolerance causing because of centrifugal force that runs up.
Adopt tool orthogonal rake Ang2 of the present utility model to be 5 °～7 ° and can strengthen cutter bending strength and toughness, improve sharpness, effectively reduce smear metal grinding resistance, and then reduce the distortion that causes of heat in metal cutting, the design of primary clearance can effectively reduce cutter wearing and tearing below, improves cutter life; Tool cutting edge angle Kr is 93 °～95 ° can effectively reduce resistance to cutting, and cutting edge effective length and nose angle increase, and the heat radiation situation of cutter further improves.
Brief description of the drawings

Fig. 2 is for aluminum-base silicon carbide composite aperture cutting tool for boring cutter head angle schematic diagram.
Detailed description of the invention
As shown in Figure 2 for aluminum-base silicon carbide composite aperture cutting tool for boring, cutter hub material is carbide alloy, tool tip material is diamond, and tool orthogonal rake Ang2 is 6 °, and nose angle Ang6 is 80 °, tool cutting edge angle Kr is 93 °, auxiliary angle Kr1 is 8 °, and primary clearance Ang1 is 10 °, and front clearance Ang5 is 14 °, cutting edge inclination Ang4 is 8 °, point of a knife fillet R0.2mm; Tapering smooth transition between cutter handle of a knife and cutter head, improves cutter integral rigidity; Cutter is fixed by welding manner and cutter head, prevents that cutter head is in the lower mismachining tolerance causing because of centrifugal force that runs up.
Adopt this tool sharpening diameter range in the time of Φ 3mm～Φ 6mm aperture, the cutting speed v=10～30m/min of employing, amount of feeding f=20～60mm/min, orifice edge quality improves, produce without collapsing limit situation, machining accuracy improves greatly, and cutter life significantly improves simultaneously, just there are wearing and tearing in 10 holes of the general every processing of universal cutter, need reconditioning processing, and adopt this cutter can be machined to 200 holes, do not occur yet noticeable wear defect, aperture quality is intact, without burr and collapse limit phenomenon.
