Brief introduction of HSK knife handle

One, preface already became machining to produce the segment with important technology in treatment of high speed cutting. The processability of system of traditional BT cutting tool already can satisfy the requirement of high speed cutting hard. The abbreviate of has Germany Hohl Shaft Kegel of article of HSK (heart with at present wider application of high speed cutting) the above such as system of cutting tool of the NC5 of system of cutting tool system, KM cutting tool, Japan, BIG-PLUS all belongs to two sides cabined knife handle. And cutting tool system can undertake below high speed cutting is machined, should satisfy the following postulate: 1.

Precision of taller systematic precision system includes a system to locate clip holds precision and cutting tool to repeat fixed position precision, former the join precision that points to cutting tool and knife handle, knife handle and machine tool main shaft; Latter points to the consistency of precision of system of the cutting tool after changing a knife every time. Cutting tool system has taller systematic precision, ability makes sure high speed machines the static state with due system of the cutting tool below the condition and dynamic stability. 2.

Of system of more expensive systematic stiffness cutting tool the static, main factor that moving stiffness is influence treatment precision and cutting function. Inadequacy of stiffness of cutting tool system can bring about vibration of cutting tool system, reduce treatment precision thereby, and of aggravate cutting tool wear away, lower the service life of cutting tool. 3.

Cutting of better high speed of dynamic balancing sex machines a condition to fall, the lopsided metropolis of tiny quality creates massive centrifugal force, the quick vibration of the machine tool is caused in machining a process. Accordingly, the dynamic balancing of system of high speed cutting tool is very important. 2, the formulate of level of HSK tool system begins from 1987, established special subject working group by the 30 many units such as enterprise of lab of machine tool of university of industry of German A go smoothly and manufactory of a few tool manufactories, machine tool, user, in M.

Weck teachs the research that new-style tool system began below the leader to develop the work. Pass research the first round, the working group was referred to organization of German industry standard in July 1990 " change a knife automatically hollow handle " standard proposal. Germany announced the DIN draft standard of system of HSK cutting tool in July 1991, suggest to establish relevant ISO standard to international Organization for Standardization. In May 1992, committee of technology of tool of ISOT/TC29(of international Organization for Standardization) decision of short duration not formulate changes a knife automatically the ISO standard of hollow handle. Through the 2nd round of research of the working group, germany made the DIN69893 of formal industry standard of HSK tool system 1993. May 1996, on ISO/TC29/WG33 careful parliament, formulate the ISO/DIS12164 of ISO draft standard of the system of HSK cutting tool that is a foundation with DIN69893. After the course edits for many times, published system of HSK cutting tool 2001 ISO12164 of formal ISO standard. 3, the norms of HSK cutting tool and type of knife handle of type nextpage4, HSK 5, norms of HSK knife handle distributings 6, product of machine of conclusion Taichun essence divides Vc-85B of vertical center machine, vc-X300 of machining center machine also uses the rod of new development HSK-A63 cutting tool, the advantage is as follows: 1.

Tall tigidity 2.

Precision of superexcellent axial fixed position 3.

Superexcellent and torsional transmit 4.

Repeat precision beautiful 5.

Hilt classics dynamic balancing is corrective amount to G2.
