We see from exhibition of machine of the closest tool, tool machine already progressed to change level to high speed, especially the rotate speed coming back of main shaft is spent, 10 thousand turn above has been been very general. Use main shaft of this kind of high speed to want work, the requirement of system of cutting tool of high speed treatment is must, have the development of 2 cabined knife handle consequently, on the other hand German HSK knife handle also one of arbor that because answer,hair of this trend place exhibits. Machine tools is alleged to the requirement of cutting tool system cutting tool is not only a tool of cutting of be confined to, when processing some work however, as the function of accessorial tool machine. System of alleged cutting tool is besides cutting cutting tool, still include clip of other people of cutting tool, work to run a system, measure a system. In order to use person the requirement to tool machine nothing more than place issueing a list is shown, to amount to this purpose, outside dividing structure of body of machine a playscript with stage directions, cutting tool is chosen cooperate to also can affect integral performance.

And BIG, HMC, BTW, be grow awl handle by original 7/24, make it 2 cabined knife handle. Because the spot uses BT knife handle for long, want commutation to be knife handle of 1/10 short taper, outside dividing main shaft of tool machine itself to cannot cooperate, also need a lot of cutting tool fee, because this is very difficult. But main shaft will want henceforth more high speed is changed, must be short taper and two sides cabined for the condition, because main shaft is tectonic besides can accomplish very small-sized outside, the influence of the bearing before still can making its right falls the smallest, and because be short taper petiole itself is very so light, the stroke that trades a knife can be done very smally, apply to high speed automatic cutting tool changes. Treatment of high speed of knife handle of Capot of knife handle of HSK of BT knife handle uses knife handle technology to change an aspect in high speed, the character under knife handle requirement: 1.
Blame balance quality is small. 2.
The precision that installs main shaft is tall. 3.
Cannot reduce main shaft the union when high speed is characteristic. 4.
High speed changes function. 5.
The clip of cutting cutting tool holds precision to want tall. 6.
When high speed, the clip that cannot reduce cutting cutting tool holds power. To achieve the requirement of 1, above all knife handle is complete make it is symmetrical, and raise balance precision easily. About the requirement of 2, use two sides cabined can solve. About the requirement HSK of 3 knife handle can overcome this problem. About 4 besides the travel changing a knife that reduces cutting tool, using short taper to be able to say to be quantified gently to knife handle is advantageous. As a result of,the clip of cutting cutting tool of shrink type collet holds character knife handle make it 2 cabined, installation of reason knife handle can rise to the precision of main shaft a lot of, but precision of cutting tool of the cutting after because still be expressed finally,clip is held now, clip of cutting cutting tool holds means to side solid clip is held, collet clip is held, shrink type clamp, among them shrink type clamp rotates to main shaft the situation that creates clip to hold force to reduce is less, and because construction is simpler, the precision that installs cutting tool also is above in what carrying clip to maintain pattern highest, and its defect is, every arbor uses measure one kind only, if collet locking knife handle shares a gender,cannot reach cutting tool high to tear open outfit beard to special apparatus ability disassembles installation. The property that knife handle of type of shrink of shrink type knife handle removes plane of instrument conclusion tool heals tall, the role of cutting tool system is more and more important. Must regard cutting tool system as as tool machine manufactory machine tools partially, and try hard to develop further, can make progress by what develop machine tools at the outset and realize the value of cutting tool system so, appear then more high-powered high speed treatment uses machine tools.
