Well-known, as a result of economic reason, business demand increases production ceaselessly efficiency and reduce manufacturing cost. To this, those who have conclusive effect is the quantitative class of these eigenvalue. Before a few years, the leader that produces a business is reduced to making charge 5% quite satisfactory already. But, as a result of material price rise, come from the pressure on Asian area value especially, the industry will rise productivity and the expectation cost that reduce manufacturing cost to do bigger rise, for example, industry hope improves manufacturing efficiency 30 ％ taller even, just be better cause. Most enterprise is used in the decision contemporary and efficient however before the manufacturing facilities with very high however price, going up somehow should try above all use existing device whether the task that solves them, there are a lot of possible ways in this respect. And among them a kind of possibility is to use contemporary cutting cutting tool, adopt the geometrical form of new cutting tool material, coating and cutting edge, can improve cutting efficiency significantly. And in this respect, to milling treatment, still the 4th element is in effective: Milling strategy. Belong to LMT (La Zhi) the cutting tool of member of group of metallic processing technique makes member Fette(www.

Fette.

Com) can say was to use this 4 element, the milling cutter product that makes this plant new -- Multi Edge Feed had efficient cutting property. This kind of cutting tool can be used on general accuracy machine tool. This kind of new-style cutting tool product has different structural type, and their common characteristic is: Have the geometrical figure that suits high speed feed. The feature of appearance of this kind of geometry is cutting edge have a very big circular arc radius (with the circle but photograph of dislocation razor blade is compared) , such a few restricted axial penetration of a cutting tool to measure Ap, as a result of K of lesser tool cutting edge angle, make the load of radial cutting power on milling cutter reduces effect greatly, can be without thereby scruple the ground uses very tall every tine feed. Processing steel when, every tine feed can achieve Fz=5mm at least. Raise material excision rate to adopt strategy of this kind of milling significantly, raise feed rate below the circumstance that reduces amount of axial penetration of a cutting tool namely, material excision rate can rise greatly most 500% , this conduces to reduce operating costs significantly. Measure very big rough machining to cutting especially (in be being made with the mould in the tool, this is the situation that often encounters) for, criterion profit will be more sizable. Current, be in Fette company, the milling cutter of integral hard alloy of Multi Edge series and of but the milling cutter of dislocation razor blade, have the characteristic that suits milling of high speed feed. According to the structure of cutting tool of Multi Edge series, this company can be offerred have 2, all sorts of 3 milling cutter with 4 cutting edge. Multi Edge 2Feed is a kind of whole hard alloy that has two cutting where a thing can be put to best use establishs milling cutter. This company already can offer a diameter to be in of 1mm above this kind establishs milling cutter. This milling cutter has on length particularly short, shorter with 3 longer kinds of different structures. According to the experience of Fette company, these cutting tool can satisfy the extremely high demand to machining stability, also can agree with tool with the mould the cutting tool in making often needs with bigger dangerous extend the treatment that will undertake. For example: The cutting of milling cutter of Multi Edge 2Feed that is 12mm with a diameter machines number of a kind of material for 1.

The workpiece material of 2312 is qualitative (press DIN of German industry standard, the material of this kind of number is 40CrMnMoS8.

Steel of 6 alloy tool -- interpret is noted) . Use following cutting dosage: Cutting speed Vc=237m/min, axial penetration of a cutting tool measures Ap=0.

8mm, radial penetration of a cutting tool measures Ae=8mm. To cutting tool of this kind of small diameter, every tine feed can achieve Fz=1mm at least, and feed speed achieves Vf=12.

6m/min. Suiting the milling cutter of Multi Edge 3Feed that uses high speed feed is a kind of triangle that has 3 cutting where a thing can be put to best use but dislocation razor blade, its cutting edge shows arc and have a bit raised. But the Yu Gang of application of hard alloy matrix that dislocation razor blade differs with its and cast-iron treatment. In addition, with its cubic nitrogen changes boron (CBN) change model the treatment that breed uses at workpiece of oil hard data. Here, milling cutter diameter is 32mm, of 3 but dislocation razor blade, grind on the cutting edge of razor blade of CBN Multi Edge 3Feed the protection that strengthens edge intensity pours arris. Be by treatment material number 1.

2379 (this kind of material fastens X155CrVMo12.

1, also be steel of tool of a kind of alloy -- interpret is noted) , workpiece temper by dipping in water is appeared, its hardness amounts to 63HRC. Because be in,are many apertures on workpiece, this meeting causes treatment difficulty, bring about interrupted cutting in the meeting when milling namely. Following cutting dosage uses when milling: Cutting speed Vc=322m/min, axial penetration of a cutting tool measures Ap=0.

2mm (total material excision volume is 2mm) , radial penetration of a cutting tool measures Ae=15mm, on hard work of this kind of temper by dipping in water every tine feed can amount to Fz=0 at least.

5mm, feed speed achieves Vf=4.

8m/min, use treatment doing type, the result that milling place achieves leaves deep impression to the person: Although the Multi Edge 3Feed of CBN is in below this kind of condition that is hard to machine, cutting tool life still exceeds 19m. Still have the Multi Edge 4Feed that uses 4 cutting edge but dislocation razor blade, when rough machining, use this to plant but dislocation razor blade (edge circular arc as much in a way is outward and raised) milling cutter can improve productivity significantly. This kind of razor blade and use a circle but the effect when dislocation razor blade undertakes machining compares: The workpiece material of treatment is CK45 character (the tone qualitative steel with commonly used department -- interpret is noted) , milling cutter diameter is 42mm. In same time material excision leads the result that improved 5 times milling to show: Using a circle but when dislocation razor blade undertakes milling, achieved material excision rate is 100cm3/min, and use Multi Edge 4Feed but when dislocation razor blade undertakes milling, according to the data of Fette company, in same time rate of its material excision can rise of 5 times. The cutting dosage that uses here is: Cutting speed Vc=220m/min, axial penetration of a cutting tool measures Ap=0.

6mm, radial penetration of a cutting tool measures Ae=30mm, every tine feed can achieve quite tall value Fz=3 significantly.

6mm, feed speed achieves Vf=30m/min. So tall cutting efficiency need is add use new coat -- MultiC. This kind of coating is a kind of double lubricious coating: In can besmear before dislocation razor blade Al6 (AlCrN, azotic chromium melts aluminium) and besmear at the back TiN (nitrogen changes titanium) coating. This kind of compound coating suits to be used at efficient milling particularly, in addition, this kind of compound coating can facilitate wear away with what will identify cutting tool. Conclusion: This kind can use the cutting tool of high speed feed, suit to be used particularly improve manufacturing efficiency, this kind of milling cutter is OK also use on existing machine tool.
