Well-known, aperture axis cooperates is the cell that comprises mechanical product, aperture axis cooperates quality to affecting the quality of the product directly, and the quality of aperture is among them crucial, wait like car engine, gear-box, the function index such as sex of the noise that the aperture on its fastens quality to affect a car directly, driving flexibility, balance. In the light of nicety of short of of current and homebred cutting tool aperture machines the requirement of craft, accurate Kong Jia is versed in cutting tool needs the current situation that 100 ％ import, company of tool of machine tool of collate of Beijing division stone passes nearly 10 years of much effort, development went a kind of high speed inside reamer of series of cold pattern KKJ. KKJ series reamer has material qualitative tenacity the character such as good, wear-resisting, workmanship has not at traditional reamer, can be in jumpy control 0.

001 μ M is the following; The opening that bore with a reamer gives achieves the precision of aperture of 7 class, 6 class easily to ask, even the precision requirement of aperture of 5 class, 4 class; Aperture circularity is less than 1 μ M, cylinder is spent be less than 1.

5 μ M. The characteristic of cold pattern reamer inside KKJ high speed is: Precision of aperture of ● bore with a reamer is tall; ● is hard to exceeding for material, finished cost is low; ● need not is opposite in big batch production Dao Yi, reduced labor intensity, improved manufacturing efficiency; ● gets used to all sorts of cutting parameter of the machine tool; ● is average the cost of every aperture should be reduced than using entrance cutting tool multiple. The gun type reamer in KKJ series and much couplet reamer are to be aperture of nicety of cutting of high speed of numerical control machine tool, efficient tall simple treatment only and form a complete set develops. The characteristic of extraordinary of reamer of wear-resisting of NC high accuracy is an operation handy, do not need any debugging, do not need pair of costly Dao Yi to undertake iteration debugging more, realize the finish machining of aperture easily. Because this reamer does not need to debug, avoided the occurrence of the reject in debugging. Below similar cutting requirement, than the Chan Ren that uses at present the feed of boring cutter and boring reamer wants big a lot of. Cold pattern reamer uses cutting inside KKJ high speed type design flows inside fluid, stock of central edge axial one aperture is direct blade ministry each aperture, the cutting liquid that has constant pressure is in from handle end infuse each aperture develops blade department, swept all scrap iron that produces in cutting process already, cool adequately again and lubricated edge. In use equipment lack offers cutting when type unit shedding inside fluid, also but from exterior and pouring cutting fluid, but cutting rate can fall somewhat, ask exterior cutting fluid wants to assure constant pressure at the same time. Cold pattern reamer is machining quality to go up not only inside KKJ high speed can rival with entrance reamer photograph, and the characteristic that still has life to grow, can reduce the treatment cost of aperture effectively, be like: Be opposite gear-box steeliness in the precision work that moves entry, the service life of KKJ reamer is the 10 times above of high-speed steel reamer and reamer of general hard alloy; In the treatment to aperture of connecting rod bolt, the service life of KJJ reamer also is the 10 times above of general reamer. In the meantime, use KJJ reamer still can come true to take the place of with bore with a reamer top gem. CNC Milling
