Hard metal treatment uses drill cutting cutting tool to go up additional the TiAlN coating of bicron ply, can improve the efficiency of hard metal cutting. This method scope of application is wide, apply to all sorts of cutting speed and the treatment of hard metal cutting that get aperture deepness. The result that the comparative experiment of course and common drill reachs makes clear, compare with common drill, add the cutting cutting tool that has TiAlN coat, service life lengthened 20% ～ 40% , productivity rose 85% . When use drill undertakes metallic cutting is machined, it is difficult that all obstacles that in can overcoming treatment process, the coating of cutting cutting tool must appear are mixed. When undertaking transverse cutting, need calm bore center above all, determine the user demand to bore quality even, and the rate of cutting is average unchallenged, the requirement of the tall attrition force that the coating that the most important is cutting cutting tool needs when according with cutting to work, arise. When exercise the meeting when cutting tool reachs top operating speed produces high temperature, broach cut blade and blade arris must be had very tall high temperature resistant function. When having a test, workpiece is the steeliness work that uses quality to reform (42CrMo4V) , tiAlN coating is added on the cutting tool of drill, when undertaking transverse cutting, tiAlN coating still can effective protection cutting tool, cutting tool and blade of cutting tool cut wear away the requirement of cutting tool of even drill cutting asks the hardness of drill cutting cutting tool wants on one hand tall, and have good adherent capacity, and when on the other hand cutting cutting tool works, be in cutting chamfer, this asks its coating wants again very flowing, such, it is when bore is very deep, of cutting drossy and OK go out smoothly from aperture inner tube. The coating that drill cutting cutting tool adds must material has pledged, have immense adherent power, hardness is tall, high temperature resistant, and it is good to fight oxidation function. The coating of cutting cutting tool of the Blinit Pertura research and development of company of coating of German Oerlinkon Balzers can satisfy afore-mentioned requirement. Oerlinkon Balzers company applies an institute in hamburger technology (HVW) the lab undertook contrasting experimenting, sample of on the cutting tool coating that is fundamental material with the titanium aluminium alloy of this company research and development and market two common coating of drill cutting tool undertake contrasting experimenting, the result makes clear, the Blinit Pertura coating of bore cutting tool can satisfy adherent force completely, hardness is tall, high temperature resistant and it is good to fight oxidation function. Two when be used at this contrast to experiment common drill cutting tool are the diameter that sells on the market normally for 5.

The bore cutting tool with the high grade qualitative rolled steel of the cast-iron bore cutting tool of 5mm and tall hardness. When undertaking cutting machines exercise to experiment, workpiece is the steeliness workpiece with improved quality, the cutting that experiment place undertakes works even if run-of-mill cutting treatment works, minim lubricant is used in exercise. The Blinit Pertura coating of bore cutting tool is special apply to transverse cutting, can protect cutting tool. In exercise cutting cutting tool and cut blade wear away even. Contrary, the cutting cutting tool that sells on the market normally appears a side wears away, the desquamation of occurrence fission. And after using the 42m of exercise of cutting cutting tool that adds the Blinit Pertura coat that has research and development of Oerlinkon Balzers company, broach still in good condition nondestructive. Contrast experiments to make clear further, the aperture shapeliness of use cutting, and accord with dimension requirement strictly. Contrary, the common cutting cutting tool that sells on use market undertakes cutting works, cut blade occurrence fission falls off, stick together, or when transverse cutting, because wear and tear is serious, cut blade a side appears wear away. To more following than experimenting to still reach result: The common cutting cutting tool that sells on use market undertakes appearance of cutting exercise cutting is differred, the quality stand or fall of bore is differ, occurrence dig cuts accumulation. General cutting 35m or 29m need to change the cutting tool of drill. And appear in cutting tool when rupturing, still must change at any time cutting tool. In high speed cut when cast-iron workpiece, the drill of cutting tool coating that adds the titanium aluminium alloy that has Oerlinkon Balzers to be fundamental material more have advantage. After use minim lubricant completes the work of 1000 aperture, the ability on the coating cutting tool that adds aluminium alloy having titanium to be fundamental material and cut blade appears to wear away equably. Although the temperature when exercise is special tall, but the cut blade of cutting tool still is stabilized. Just be in the point of a knife of cutting tool and advocate the excessive place of the knife appears arris. The experimental result of the partner HVW lab that contrast experiments points out, the common cutting cutting tool that sells on use market undertakes cutting works, undertaking transverse cutting is opposite of cutting tool wear away when increasing, a side of blade of cutting tool cut appears wear away in cutting tool advocate the excessive place of knife and point of a knife can appear rupture or by the phenomenon of hollow. Blinit Pertura can add the comparative test that raises lab of HVW of treatment exercise economy to make clear afresh, with the drill of Blinit Pertura coating cutting tool can use the work that processes any material to pledge, in order to improve the economy that cutting treatment works, compare with photograph of common drill cutting tool, used the service life that adds the drill cutting tool that has Blinit Pertura coat to lengthen 20% ～ 40% , productivity rose 85% . In addition, add the drill cutting tool that has Blinit Pertura coat to be able to have safe operation below any cutting speed. In addition, adding after Blinit Pertura coating wears away, still can add this coating afresh, and have as same as the coating that adds first durable function. With use common cutting tool photograph to compare, repeat add coating of this kind of cutting tool 3 times, can reduce drill cutting tool of 50% purchase cost. The experiment returns a proof, this kind adds the cutting tool that has Blinit Pertura coat adherent function beautiful. When undertaking transverse cutting especially, its adhere to function still very good. In addition, still have the advantage with position good performance, ensured the aperture of drill cutting is accurate so, quality is reliable. When cutting processes work, can give drossy and very good region, ensure treatment exercise goes on wheels. CNC Milling
