Cutting tool so name, instantaneous be clear at a glance! Read this text book rapidly of type name regulation!Be opposite by different cutting tool type cutting tool in group category group 1 Xxyyy (milling cutter kind) : 110 spherical milling cutter (cylinder milling cutter, ever since alphabetical Y represents milling cutter diameter, be the same as slightly below) 120 establish milling cutter 140 planar milling cutter 2 Xxyyy of group of category of knife of 150 garden Pan Xi (broach kind) 200 twist drill (ever since diameter of broach of alphabetical Y delegate, be the same as slightly below) 220 centers broach tap of 240 normal whorl (ever since alphabetical Y is OK and divisional thick tooth whorl is fine perhaps tooth whorl) 3 Xxyyy of group of 250 reamer category (boring cutter kind) 300 Shuang Ren thick boring cutter (ever since diameter of boring cutter of alphabetical Y delegate, be the same as slightly below) 4 Xxyyy of group of category of boring cutter of essence of 320 odd blade (reaming knife) 400 reaming knife (ever since diameter of knife of reaming of alphabetical Y delegate, be the same as slightly below) category group 5 Xxyyy (lathe tool) : 500 thick lathe tool (ever since the numerical value of circular arc of point of a knife of alphabetical Y delegate, be the same as slightly below) 510 essence lathe tool 520 grooving knife (ever since width of point of a knife of alphabetical Y delegate, be the same as slightly below) 530 cut off lathe tool 540 whorl lathe tool (ever since alphabetical Y can represent thick tooth the parameter such as whorl of fine perhaps tooth) special cutting tool of category group 7 Xxyyy, the meaning of alphabetical Y inspects particular case and decide citing to be as follows ever since: T110010 expresses a diameter the spherical milling cutter of 10 millimeter; T200020 expresses a diameter the twist drill of 20 millimeter; T300100 expresses a diameter the double blade thick boring cutter of 100 millimeter; T400110 expresses a diameter the reaming knife of 110 millimeter; T500008 states circular arc of point of a knife is the thick lathe tool of R0.8 millimeter. Itself of date of the cutting tool in means of this kind of number included conclusion a lot of content such as cutting tool type, specific type and dimension, make process designing member be opposite with jockey the use circumstance be clear at a glance of each cutting tool, do not have in machine tool program especially Chinese the number method that this kind uses to unite below the case that turn, the process that can machine to numerical control not only has more intuitionistic knowledge, prevent the quality accident that use cutting tool because of the mistake and causes; Reduce treatment to plan time greatly, improve manufacturing efficiency; Make the cutting tool government of the enterprise works at the same time more standardization, science is changed, raise the automation level of cutting tool management, achieved the goal that fast inquiry and cutting tool resources use effectively, in applying to machine tool of of all kinds numerical control. Nevertheless, because the numerical control machine tool of each unit and cutting tool type are endless identical, afore-mentioned methods still have inadequacy; Here puts forward a kind of train of thought of the individual only, the hope can have the effect of cast a brick to attract jade-offer a few commonplace remarks by way of introduction so that others may come up with valuable opinions, inappropriate place still asks each expert criticism, point out mistakes so that they can be corrected. When the factor that affects choice of numerical control cutting tool is choosing the type of cutting tool and norms, basically consider the impact of the following element: (1) the lot size that productivity pledges what produce property to point to here is a spare parts, basically consider the impact that chooses to cutting tool from finished cost. Be in for example mass-produced when use special cutting tool, the likelihood is economical, and in sheet or when small lot is produced, choice standard cutting tool suits more a few. (2) the numerical control machine tool that machine tool type finishs place of this working procedure to use is right the cutting tool type of the choice (get, lathe tool or milling cutter) influence. Below the condition that can make sure workpiece system and tigidity of cutting tool system are good, allow to use the cutting tool of tall productivity, for example lathe tool of high speed cutting and big feed lathe tool. (3) the cutting tool that the numerical control with different program of numerical control treatment machines plan to be able to use different type. For example the treatment of aperture can be used auger reach reamer, usable also get and boring cutter will undertake machining. (4) the choice that the dimension of the dimension of workpiece and appearance workpiece and appearance also affect cutting tool type and norms, for example special model the surface should use special cutting tool to machine. (5) the structural form that processes exterior surface roughness to machine exterior surface roughness to affect cutting tool and cutting dosage, for example when semifinished product thick mill is machined, can use thick tine milling cutter, serration milling cutter had better be used when mill of essence of life. (6) the type that processes precision to machine precision to affect finish machining cutting tool and structural appearance, for example the machines basis aperture finally precision of aperture is usable auger, reamer, reamer or boring cutter will machine. (7) the alternative that material of workpiece material workpiece will decide cutting tool material and parameter of cutting part geometry, hardness of the treatment precision of cutting tool material and workpiece, material about. The performance demand of numerical control cutting tool has treatment precision as a result of numerical control machine tool working procedure of tall, treatment centers efficiency of tall, treatment and spare parts outfit places the characteristic with little time, the numerical control cutting tool that uses to place raised taller requirement. Tell from cutting tool function, numerical control cutting tool should the cutting tool that place of prep above general accuracy machine tool uses. When choosing numerical control cutting tool, should answer above all preferential choose standard cutting tool, just can choose all sorts of efficient compound cutting tool and special special cutting tool when necessary. When choosing cutting tool of standard numerical control, should join real case, choose all sorts of advanced cutting tool as far as possible, be like but cutting tool of cutting tool of dislocation cutting tool, integral hard alloy, pottery and porcelain. When machine tool of choice numerical control machines cutting tool, return the issue that should consider the following aspects: (1) the type of numerical control cutting tool, norms and accuracy class should satisfy treatment ask quite, cutting tool material should suit with workpiece data phase. (2) cutting performance is good. Amount of large back penetration of a cutting tool and tall feed can be used when to get used to cutting tool to be in rough machining or the workpiece to difficult treatment material are machined, cutting tool should be had can bear the function of high speed cutting and puissant cutting. In the meantime, same approve cutting tool to must be stabilized in cutting function and respect of cutting tool life, so that come true,change a knife by cutting tool service life or undertake administrative to cutting tool life by numerical control system. (3) precision is tall. The high accuracy that machines to get used to numerical control and change the requirement such as the knife automatically, cutting tool must have taller precision, if some whole form of characters or letters establish the radial of milling cutter,dimension precision is as high as 0.005mm. (4) reliability is high. Cutting tool accident won't happen to injury reachs potential defect and affect the success of treatment in wanting to make sure numerical control is machined, requirement cutting tool and the accessory that combine to it must have very good dependability and stronger adaptability. (5) durability is tall. The cutting tool that numerical control machines, it is no matter in rough machining or finish machining, should have taller than treatment of general accuracy machine tool uses cutting tool durability, wear cutting tool and the number to the knife with decreasing to change or be repaired as far as possible, the treatment efficiency that improves numerical control machine tool thereby and assure to machine quality. (6) it is good to judge bits and platoon bits performance. In numerical control treatment, stop bits and treatment of general accuracy machine tool of the unlike that discharge bits in that way can seasonable by artificial processing, cut bits easy twine go up in cutting tool and workpiece, meeting attaint cutting tool and cut workpiece already machined the surface, can produce person and equipment accident even, the safety that affects treatment quality and machine tool moves, it is better to ask cutting tool is had so judge bits and platoon bits performance.
