The broach of new-style hard alloy of OSG company new development, can machine L/D=20 ～ the alveolus of exceeding operational depth of 26. Main characteristic: ① uses 3 chamfer special slot, core is thick bigger, groovy cut area is larger, can make sure broach has enough tigidity; Treatment of ② deep aperture must adopt section to machine, it is what generation machines every time below the look as far as possible to cut bits, groovy length is shorter, in order to ensure the tigidity of the tool; Classics of ③ cutting blade pours arris processing, can reduce axial force, rise cut function; Base material is ④ imperceptible grain hard alloy, handle via TiAlN coating, make wearability rises further. If use 1. 5mmFHL broach processes HPM38(53HRC) data, hole depth 40mm(L/D=26) , this is treatment of alveolus of a kind of exceeding operational depth, the service life of FHL broach obtains treatment more than 90 aperture, general broach cannot reach this one level.
