1. Cutting tool can divide the phyletic CNC Machining of CNC Machining cutting tool to be mixed for groovy cutting tool modular cutting tool two kinds big. Modular cutting tool is development direction. Development is modular the main good point of cutting tool: Reduce the machine down time that change a knife, increase manufacturing handling time; Accelerate change knife and installation time, improve the economy that small lot produces; Raise the rate of the standardization of cutting tool and rationalize; The management that improves cutting tool and flexible the level of treatment; Enlarge the utilization rate of cutting tool, develop the property of cutting tool adequately; Eliminate what cutting tool measures the job effectively to interrupt a phenomenon, can use the preliminary adjustments outside the line. In fact, as a result of the development of module cutting tool, numerical control cutting tool already formed 3 old systems, namely system of turning cutting tool, auger cut cutting tool system and system of boring mill cutting tool. (１ ) can divide ② of type of the whole that it is ① to enchase type to be able to be divided from the structure to solder type and machine place type. Machine clip type differs according to cutter hub structure, cent is but dislocation and not dislocation; ③ is decreased brace up type grows when the working arm of cutting tool when the comparison with the diameter is big, to reduce the vibration of cutting tool, raise treatment precision, use this kind of cutting tool more; Fluid of cold pattern cutting passes cutter hub interior inside ④ arrive by spray orifice eject the cutting blade ministry of cutting tool; If ⑤ special type is compound cutting tool, reversible attack thread tool to wait. (2) high-speed steel of cutting tool of the high-speed steel that it is ① can be being divided on the data that uses from production place is normally model base material, tenacity relatively hard alloy is good, hardness, wearability and red rigid relatively hard alloy is poor, unwell at cutting hardness more expensive stuff, unwell also at undertaking high speed cutting. Blade of generator proper motion needs to grind before high-speed steel cutting tool is used, and blade is ground convenient, comfortable at all sorts of special need nonstandard cutting tool. Performance of cutting of razor blade of hard alloy of ② hard alloy cutting tool is superior, be used extensively in CNC Turning. Hard alloy razor blade has product of standard norms series, specific technology parameter and cutting function produce manufacturer to offer by cutting tool. Hard alloy razor blade is 3 kinds big by international standard cent: P kind, m kind, k kind. P kind -- comfortable at machining steel, malleable iron length bit (the YT that is equivalent to our country kind) M kind -- comfortable wait at machining austenite stainless steel, cast-iron, tall manganese steel, alloy cast iron (the YW that is equivalent to our country kind) M-S kind -- comfortable at machining heat-resisting alloy is mixed titanium alloy K, grooving, cut end panel, cut chamfer of end panel annulus, cut off etc. The machine that numerical control lathe uses a level commonly is placed but dislocation cutting tool. Machine clip but the razor blade of dislocation cutting tool and cutter hub have a level, bit material uses hard alloy, coating hard alloy and high-speed steel. Machine of numerical control lathe is placed but type of dislocation cutting tool has outside round cutting tool, outside thread tool, inside round cutting tool, inside thread tool, cut off cutting tool of labour of cutting tool, Kong Jia (include central aperture broach, boring cutter, tap to wait) . When dislocation cutting tool places solid not to worry bit again, machine clip can use bolt, bolt normally pressing plate, bar is sold or the structure such as wedge piece. Groovy turning cutting tool is strip form square cutter hub or columnar arbor. Quadrate cutter hub uses bolt of groovy form tool carrier to tighten solid means to secure commonly. Columnar arbor is to use sleeve bolt to tighten solid means to secure. The connection between they and machine tool bit body is to pass groovy form tool carrier and sleeve extension bar to come of connection. Be in modular in turning tool system, the connection of bit body is with connection of system of rack type power much, and the connection of knife head and cutter hub is " insert change type system quickly " . It can be used at already outside round turning can be used at again inside aperture boring, what also apply to turning center is automatic the system that change a knife. The cutting tool that numerical control lathe uses is 3 kinds from the cent on cutting means: Cutting tool of cutting tool of round face cutting, end panel cutting and central aperture kind cutting tool. ② getting cuts cutting tool to divide alveolus, short aperture, deep aperture, attack aperture of whorl, bore with a reamer to wait. Auger cut cutting tool to be able to be used at center of numerical control lathe, turning, can use at milling machine of numerical control boring and machining center again. Because its structure is mixed,connection form has a variety of. Clench of snail of straight handle, straight handle is decided, connection of awl handle, whorl, module type connection (conic or columnar connection) etc a variety of. ③ boring cutting tool divides the cutting tool such as boring of thick boring, essence of life. Boring cutter can be divided from the structure mix for handle of boring cutter of type of handle of integral type boring cutter, module boring head kind. Can divide from treatment craft requirement for thick boring cutter and boring cutter of essence of life. Mill of face of cent of ④ milling cutting tool, establish the cutting tool such as mill, 3 blade mill. ● face milling cutter (also call Duan Xi the knife) there is cutting blade on the circumferential surface of face milling cutter and end panel, blade of the cutting that carry a department is deputy cutting blade. Face milling cutter makes whole set type set tine structure and bit machine clip more but dislocation structure, tooth material is high-speed steel or hard alloy, cutter hub is 40Cr. ● establishs milling cutter to establish milling cutter is a kind of milling cutter that uses at most on numerical control machine tool. The cylinder that establishs milling cutter has cutting blade on the surface and end panel, they can undertake cutting at the same time, also can undertake cutting alone. The structure has integral type and machine clip type to wait, high-speed steel and hard alloy are the commonly used material of section of milling cutter job. You Lixi knife develops milling cutter of mould of ● mould milling cutter and become, can divide the taper that it is a circle to stand milling cutter, cylindrical ball head stands milling cutter and head of round cone-shaped ball to establish milling cutter 3 kinds, its petiole has straight power, cut smooth model straight handle and Mohs awl handle. Its structural characteristic is a ball cutting blade is bestrewed on head or end panel, circumferential blade and circular arc of ball head blade join, can make radial and axial feed. Section of milling cutter job uses high-speed steel or hard alloy is made. Milling cutter of figuration of ● of milling cutter of form of beat of ● of ● keyway milling cutter (4) special model cutting tool is special model the knife is had take a handle to tighten collet, puissant pinchcock oneself head knife handle, reversible type (automatic and retrorse) attack whorl collet knife handle, add fast collet knife handle, compound. 2. The characteristic of CNC Machining cutting tool to achieve efficient, much can, change quickly, economic purpose, CNC Machining cutting tool and photograph of cutting tool of common metal cutting have the following characteristic than answering: ● razor blade reachs the generalization of knife handle height, normalization, seriation. The durability of ● razor blade or cutting tool reachs the rationality of economic life index. The standardization of ● cutting tool or bit geometry parameter and cutting parameter, model is changed. ● razor blade or cutting tool material and cutting parameter and be machined should match between material. ● cutting tool should have taller precision, the dislocation of the relative position precision to machine tool main shaft, razor blade and knife handle reachs the appearance precision that includes cutting tool, razor blade and knife handle tear open of outfit repeat precision. The intensity of ● knife handle wants tall, tigidity and wearability to be close friends. The outfit machine weight of ● knife handle or tool system has limit. The position that ● razor blade and knife handle cut and direction have a demand. The fixed position of ● razor blade, knife handle is standard reach change knife system automatically to want to optimize. The cutting tool that uses on numerical control machine tool should satisfy installation to adjust convenient, tigidity good, precision tall, durability is good wait for a requirement. CNC Milling
