日本富士精工在铰削大量含硅的铝合金铸件过程中,研制成功一种具有高耐磨性的金刚石铰刀,正在申请专利.这种铰刀与以往的硬质合金铰刀相比,加工成本降低,使用寿命为硬质合金铰刀的50倍以上,并可提高工件的加工精度.该公司目前计划每月生产200—250把这种新型铰刀.高硅铝合金铸件的铰削加工,现在一般都用硬质合金铰刀,但这种铰刀加工的上限是含硅18%的铝合金铸件.而且磨损显著,使用寿命很短.富士精工研制的新型铰刀,即使加工含硅21%的铝合金铸件,也不会出现异常磨损.而且,这种新型铰刀在加工过程中不易发热,因此不会出现加工面成分变化
Japan’s Fuji Seiko in the process of reaming a large number of silicon-containing aluminum alloy castings, the successful development of a high wear resistance of the diamond reamers, is applying for a patent. This reamer compared with the previous carbide reamers, machining Cost reduction, service life of 50 times more than cemented carbide reamers, and can improve the machining accuracy of the workpiece.The company is currently planning to produce 200-250 a month of this new type of reamer .High-silicon aluminum alloy casting reaming , But now generally use carbide reamers, but the reaming of the upper limit of the alloy is 18% of silicon castings and wear significant, very short life expectancy. Fuji Seiko developed a new reamer, even if the processing of silicon 21% of the aluminum alloy castings, and will not be abnormal wear and tear. Moreover, this new reamer is not easy to heat during processing, so there will be no change in the composition of the processing surface
