As what ask to machining the task increasingly grow in quantity, also guide those who sent cutting tool measure to grow continuously continuously. Right now the capacity of in-house knife library is put in ultimate problem. And use exterior knife warehouse, criterion slue this kind of situation. The user of equipment of machine tool of most numerical control can encounter library of machine tool knife to cannot satisfy used issue, because the amount of cutting tool wants to be satisfied at differ and machining flow complexly,this is. The often is basis machine tool certainly investment of cutting tool amount plans the technical standards with the machine tool, perhaps say to invested a budget to decide to be able to use a certain quantity of cutting tool only. Because each position in knife library means cost. During deciding the basis of cutting tool amount is investment program, the machine tool of place control needs the workpiece sort of treatment. Rise increasingly as what ask to machining the task, requires cutting tool amount also often is met step up, perhaps be in task of big batch treatment, can use the cutting tool of a few similar, in order to realize the exercise circuit that automation operates. Here the circumstance falls, need revest to machine tool equipment or machining center, in order to increase the cutting tool amount in knife library, need to adopt a hand to move between main shaft and in-house knife library otherwise change a knife, but this kind of means often can affect manufacturing efficiency. Raise a machine tool to do not suffer model of CNC machine tool and the effect of production manufacturer produce can make exercise provides flexibility more, gelenauer company rolled out a device of new-style exterior knife library to the market (graph 1, 2) . This small and medium sized business that is located in Sa Kesen city has 100 stuff, the treatment business that basically pursues a machine tool making the component of the industry supply money business and accurate component and large part up to now. Graph 1 have 60 knives those who be used at SK-40 cutting tool is modular exterior knife library of the structure. Odd the greatest weight of a cutting tool is 12kg, the length of cutting tool but aleatoric make choice of pursues 2 set in CNC general-purpose on milling machine, have 60 knives exterior knife library. The product that the movement that change a knife carries out library of knife of exterior disk type to be set in company of Gelenauer of a side of machine tool equipment to be about to pass oneself by the robot will raise its the effectiveness of the 50 manufacturing experience that come for years and technical know-how expands its serve limits energetically. Library of designs new disk type knife can is in by the setting a side of the machine tool. Decorate to what knife library furnishs, still should depend on finally the position of library of knife of interior of the state of user workshop field, machine tool, cutting tool changes dot and cutting tool are deferent the element such as means. The flow changing a knife between in-house knife library and exterior knife library can pass a 6 axes robot or through another deferent unit (contain the linear unit that pays claw) will come true. In process of whole research and development, basically consider the investment cost of new-style knife library and current performance. Accordingly, design personnel used the principle of standard component on knife library. On the base of a whole the level set aluminous qualitative bit body, knife handle is set on bit body. Every bit body can admit 30 cutting tool at most. To enlarge the capacity of library of disk type knife, can put 5 bit body in order to overlap most, can reach the library capacity of 150 cutting tool greatly most from this. Because use integral base, because this is exterior,knife library needs only 1. The position of 21m2, and the effect that does not suffer a Chu Dao to have an amount. Cone-shaped knife handle is installed on bit body, the fibre glass that chooses capable person is tall tenacity character is strengthened model plastic. This kind of material is special wear-resisting caustic, can protect cone-shaped knife handle to escape damage bad. The cutting tool of the SK40 that designs knife library applies to those to accord with DIN69871 to set, HSK A63 that accords with DIN 69893-1 regulation and interface of Coromant Capto C6. The cutting tool put in storage of large size is unchallenged also. If not the photograph adjacent knife of plan place closedown if, diameter of the biggest cutting tool can amount to 100mm. Same, because be used between each bit body adjustable clapboard, the length because of this cutting tool not very important. The drive of bit body runner shaft is carried out through electric machinery of a servo. The device of V belt gear that servo electric machinery adopts a maintenance-free and drive axis photograph join. The servo axis of the device that change a knife and knife library carries out a respect in soft, hardware, be carried out by the control system of the machine tool. Raise user of treatment flexibility machine tool through using warehouse of new-style and exterior knife, can make to the new requirement of its client at any time answer quickly, and the cutting tool sort that machine treatment wants is more, manufacturing cost is lower, product range is wider. Because the versatility of integral equipment is stronger, because this is completely OK,bring into the user to the consideration to the special condition such as norms of knife handle model, cutting tool and cutting tool amount in.
