Cutting tool is the main component of the machine tool, straightforward executive production machines the task, it is the main tool that the component that finish machines. From the choice of cutting tool material, arrive again to the assembly of cutting tool the use of cutting tool, mix with treatment quality treatment precision is close together and relevant. In treatment manufacturing industry develops at full speed today, all sorts of new material, new technology emerges in endlessly, the material of cutting tool and craft also are updated in constant change in. Face the treatment requirement that raises increasingly, how to use cutting tool correctly, make of cutting tool and airport match more optimize, better cooperate to finish production to machine the task, it is the serious problem that contemporary machining domain cares generally. 1.

What cutting tool uses is basic make fun of the relation that begging is mutual depend on sb or sth for existence between cutting tool and machine tool, the machine tool that does not have cutting tool is half-baked, the machine tool is the carrier of workpiece of cutting tool treatment. The main demand that cutting tool uses is to want to match with the fundamental photograph of installation not just, also want at the same time with be matched by treatment work look. Of the appearance match, of dimension matching is cutting tool can install the fundamental condition on the machine tool, but this is only most one part of the foundation, more important is a machine tool installation cutting tool is to should use cutting tool to finish specific treatment job. And in carrying out the process that machines the task, cutting tool wants those who make sure workpiece is machined to reach tall difficulty not just, should be opposite more heat of torque of cutting force, cutting, cutting can bear, deliver and derive, this is the basic function that cutting tool place should have. Cutting tool and be machined between workpiece match contain more content. Among them the substantial that point of a knife is cutting tool, the most commonly used dot that is cutting tool and workpiece contact, also be the mainest point. The cutting function of point of a knife suffers the effect of tripartite face element, namely the geometrical appearance of figure of face of base material character, point of a knife and point of a knife. 3 person between assorted degree decided them between the size of interact, decided the function of point of a knife then. Base material is bearing to machine the major cutting power in the process and heat. Cent of nowadays base material is a variety of types, apply frequency to be hard alloy highestly among them. With hard alloy is tungsten radical exemple, tungsten is cobaltic kind of hard alloy is medium, matrix contains cobaltic amount taller, fight concussion capability is stronger. And matrix contains the horniness such as carbonization tungsten Xiang Yue is much, its hardness is taller also. In also be being machined because of the character of base material just about, if impact is minor, can choose base material to contain the cutting tool of the hard alloy with less cobalt, this kind of cutting tool can have good wearability. If impact is bigger, can choose the cutting tool that cobalt contains to measure taller hard alloy in base material, hardness of this kind of cutting tool is tall, can prevent effectively to machine the state that collapse knife appears in the process. 2.

The promotion that the property that cutting tool uses promotes cutting tool property and cutting tool coating and parameter of cutting tool geometry have immediate concern. In light of the cutting cutting tool that uses from inside nowadays machining, the coating that the cutting tool of 70 % above adds. The application of cutting tool coating has protective effect to cutting tool not only, promoted the promotion of function of cutting tool base material more effectively. Cutting tool surface adds coating to basically have the following effect: Can raise cutting tool fight wear away ability, add the service life of cutting tool effectively; Can fight crescent moon to wear away depression, prevent cutting tool to produce the tumor that accumulate bits; Can improve the quality that workpiece surface machines effectively, improve the efficiency of machining. Cutting tool coating basically is divided to measure large category, reach CVD coating and PVD coating. When making formal coating to cutting tool, the besmear pre-treatment that must make good cutting tool works. Job of cutting tool finishing is accomplished, what can make coating and cutting tool appearance better is adherent, make agglutinate is spent between coating and cutting tool matrix not only stronger, and reduced the cutting flow harm to cutting tool effectively, lower the occurence rate of small collapse knife. Good coating processing can promote hard alloy the property of cutting tool substantially, same, coating also has good protective rent to cutter hub, the adherent hard coating on cutter hub can move to high speed the cutter hub that contacts with high temperature and cutting in the process decreases wear away, because,add cutter hub face the reason of coating, lubricant degree, it is the flow with the machines generation more smooth cutting inside the chamfer that hold bit. Additional, of cutting tool before horn, hind form of the horn, chamfer that break bits, still other detail structure belongs to the category of appearance of cutting tool geometry. The inadequacy of cutting tool base material and the defect that coating treats can use the geometrical appearance of point to undertake redeeming in a lot of moment. Among them with the chamfer of cutting tool geometry influence to cutting tool function most apparent, want to its special try to take seriously. 3.

The   of basic excrement La that cutting tool uses 3. 1 proper mix holds power cutting tool to be in installation process, in the process that bolt will use to undertake tightening originallying placing holding after bit dislocation, want to notice to torque the value undertakes accurate measurement, cannot pure support experience deals with at will. Pass to add the meeting that hold power smally to affect the close solid sex of bit, assure to machine precision to accord with the requirement that workpiece machines hard; Too big clip holds force to be able to make bit bears tighten pressure is overweight and cause disintegrate. Hold power to assure to bring to bear on to be added correctly, can use torque spanner to undertake tightening solid to bolt, the profit that uses tool of this kind of spanner depends on can holding force level value to have set to clip, when achieving set to be worth, can issue signal reminder. 3. 2 control and the control that remove the cutting force of the cutting tool in oscillatory machining are very significant, control and even eliminate vibration but better control cutting strength, make sure cutting tool machines the cutting property that keeps stable. Accordingly, controlling vibration is the premise condition that program of treatment of configuration of cutting tool of any machine tool optimizes. Reduce or eliminate vibration but effective extension the lifecycle of cutting tool, and also have protective effect to machine tool main shaft. 3. In the action machining of cooling fluid of 3 sufficient play, of cooling fluid reasonable use the success or failure that matters to treatment, in undertaking aperture adds the process of labour especially, cooling fluid more appear especially important. For the broach to cooling fluid can be being offerred in machine tool cutting tool, its task is to cutting blade carries cooling fluid not just, still include to cut bits eduction to what produce treatment outside aperture. Want refrigerative fluid to produce effect adequately, be about to consider cooling fluid is transmitted and cutting transmits two kinds of elements at the same time. 3. 4 use new technology, new technology to undertake actively muti_function the development of cutting tool, satisfy much axis machine tool the need to machining cutting tool, use modular knife handle, with can matching with photographs of a variety of cutting tool of hard alloy cutting. Right but dislocation cutting blade tries to be used adequately, just machine means with combination, as far as possible the amount that cutting tool requires in reducing treatment process. 3. 5 in taking power seriously to use up the process in machining, choose to use the cutting tool with little demand of machine tool power as far as possible. Use this kind of cutting tool, OK and effective economic energy resources is used up, in advocate energetically energy-saving decrease a platoon today, more advocate the treatment method that can reduce specific power consumption. Take machine tool power seriously to use up, use appropriate cutting tool, can prolong cutting tool service life, and the loss that can reduce the main shaft to the machine tool and guide effectively, the corresponding vibration that in also can reducing cutting, causes. The place on put together is narrated, the use of the cutting tool in machining wants not only mature arrive to match with what machine the task with the machine tool degree, do the safeguard of good cutting tool even, promote cutting tool property. Follow the basic principle that cutting tool uses, science uses cutting tool, decrease to wear away needlessly, prolong cutting tool service life, thereby managing cost is devoted, get bigger economic benefits.
