No matter be the cooling water passageway of plastic pattern, barrel or hydraulic pressure crock or jet-propelled engine or the hollow axis of ship propeller, deep Kong Zuan already became serious bottleneck to restrict in too much workshop. The Kong Shi that machines high level is gotten in use gun, this kind of problem particularly apparent. When getting deepness of 4 times diameter, begin to block bits up, jump over to in worse. Broach is located in the extreme of a long and thin lever, like be just as snail to stroll slowly before row, and the circularity of aperture and position are spent bad also. These are in cutting blade begins collapse blade previously. The two class deep aperture of close research and development of Yi Si Kaxin is gotten, make these states produce above no longer. The canal of nowadays gets a system to be able to solve big diameter and big deepness completely (be as high as 300 times to grow diameter to compare) problem, exceed 5 times than efficiency with gun getting more even. Hard alloy of newest whole of small helix angle gets OK and effective ground to cover small diameter and grow diameter comparing to be as high as 22 times. In the treatment of deep oily aperture of engine crankshaft, it than soldering type gun is gotten fast 10 ％ , 6 times faster than high-speed steel broach, at the same time dependability also rises greatly. Make in the car, landing gear of turbine treatment, plane national defence and treatment, general and mechanical treatment, and the application that there is a success on oil, mine and agricultural machinery. We come to two kinds of solutions see two class deep Kong Zuan. In be in charge of type getting to cut a system, cutting head installation gets a pipe in a bit a bit smaller than bore diameter Bao Bi. Cutting fluid is entered by pump hole wall and in getting the space between the canal, cut bits from get the Kong Chong inside the canal. The macaroni look that gets with the gun is compared, this can make cutting head works on stronger base, can deliver bigger torque, bear greater cutting power, also enlarged platoon bits passageway at the same time. Final advantage is treatment faster, platoon bits is smoother. Case: Use gun is gotten, on workpiece of Ti6AL4V titanium alloy, machine 40mm of a diameter (1.

6 ″ ) , deepness 660mm (26 ″ ) aperture, the rotate speed that best workshop uses 300r/min is OK minutely treatment 12.

7mm (0.

5 ″ ) , finish 52min of a need. The hard alloy broach of use tradition has improvement a bit, but getting collapse blade begins when cutting the 2nd, bring about clutch to skid. Go up in same machine tool however, use single pipe to get, treatment efficiency is 5 times faster, a broach can finish a whole class. Tubal getting system is analytic like gun getting, this kind of single pipe gets a system (STS) need special machine tool, in orifice place need has sealed, so that maintain the cutting fluid inside. Stock deserves to direct on special machine tool set, consequently need not beforehand bore. Just need on traditional machine tool only beforehand bore. The diameter that the standard sheet canal of ISCAR gets a system to be able to be enclothed is 8 ～ 300mm (0.

315 ～ 11.

811 ″ ) , commendatory long way is compared for 10 ～ 300 times. Traditional machine tool can change his costume or dress to be gotten with Yu Shuang canal (DTS) , can reduce the demand of special machine tool. ISCAR double-barreled gets a system to be able to offer a diameter to be 18 ～ 184mm (0.

724 ～ 7.

240 ″ ) . Of ISCAR replace get and reamer head can install major main trend to get tubal system, still can choose to use but dislocation razor blade perhaps solders bit. Cover makings broach to be able to be not demarcate to make, but provide the system that is used at single pipe to get only. In running the new development that gets a system a few years of in the past, the canal got a system to had had a few new development. Above all, there were more choices to the category of bore diameter and aperture now, especially way of Xiang Xiaozhi way. Today, if use,solder the single pipe of bit gets a system, can small to 8mm (0.

315 ″ ) , if use but dislocation razor blade is OK small to 16mm (0.

630 ″ ) if be use double-barreled,get a system, corresponding diameter is OK small to 18mm (0.

724 ″ ) . The bit that the canal gets can offer material of razor blade of the IC 9025 after improving, IC520 and coating of IC908 PVD physics to pledge, such even if treatment of tall feed ground breaks bits material hard, also can prolong cutting tool life. Attention: Cut treatment as all getting, the canal is gotten when drilling the deep hole that cuts hypostatic material, also need enough main shaft power and tigidity. In the metallic purify quantity of every unit, kong Jia is versed in inherent characteristic can make it compares milling and turning to produce more clash, in cooling fluid supply and platoon bits respect waste more energy. The canal gets the situation that does not suit, with integral hard alloy the aperture to smaller diameter mixes broach to be less than a canal to get diametical aperture far, current solution is deep Kong Zuan of hard alloy of use ISCAR new-style whole. 2008 second half of the year rolls out this kind of broach, use already successfully at a lot of motivation engine to machine, include the treatment of crankshaft oily aperture. Other application circumstance has camshaft, connecting rod, crock lid, cylinder body, fluid casting die and mould. Commendatory the oldest long way compares for 22: 1. The gather of the advantage helps this kind of broach getting cut mix more quickly, more continuously, more greatly life is longer, platoon bits is safer. Nucleus of distinctive high strenth core makes auger the needle is faster, the chamfer that hold bit is deeper, the method that discharge bits is more expedite. For smooth platoon bits, helix angle design is 30 ° . The vertex angle of deep Kong Zuan that accurately air officer is much better function model only is 140 ° before horn, design quadrilateral be helpful for carrying point, reduce wallop, conduce to centering and feed. Discharging bits chamfer, the place of the brim and cutting blade did the polishing processing after coating, can reduce attrition and torque, thereby broach is OK and fast feed. To reduce attrition further, the chamfer that discharge bits has in radial degressive, getting the diameter at the back of the needle so meeting decrescent, reduced the attrition with hole wall. The design of cooling aperture can be used at various cutting fluid and treatment operating mode, also include MQL(drop lubricant) . The deep Kong Zuan with existing ISCAR can be offerred a series of standard product, diametical limits 5~10mm, grow diameter comparing to be able to amount to 20~22 times. Special dimension is OK the basis needs custom-built. The material of this kind of broach is IC908 character, this is one kind contains cobalt to measure those who be 10 ％ to exceed micron level hard alloy material is qualitative, tiAlN physics coating is contained outside. This kind of broach still can undertake weighing grinding. To more and more comprehensive treatment, the deep Kong Zuan of ISCAR brought new option for them. CNC Milling
