Get the revolution that cuts a field, unique design. Make efficiency raises 2 times, life improves the bit of 4 times! Suit cutting to process all sorts of data, can achieve every aperture the most quickly the speed broach of 1 second rotates when treatment, its external diameter is the biggest the cutting blade linear velocity of place is highest, and the linear velocity that the center plunges sharp point is equal to 0, be in static condition. If the tenacity of broach base material is insufficient, pressure of the susceptive that get a tip may cause blade of the collapse that get a tip. And wear away quickly to avoid cutting blade, requirement broach base material has taller hardness. Because common broach is made by a kind of single material, because this is when broach select material, eclectic balance must have between tenacity and hardness. And good broach stuff should be to getting sharp point to have tall tenacity, in cutting blade place criterion has tall hardness. The HardCore broach of new development of American ATIStellram company holds two kinds of property that had above concurrently. This kind of broach uses two kinds of different hard alloy names to make, the core ministry material of broach is hard alloy of a kind of imperceptible grain, the tenacity that can improve bit and when low rotate speed is machined fight concussion ability, prevent to plunge pointed collapse knife. Use the hard alloy name of tall hardness around the circumjacent share that gets core, in order to rise outside the wearability of week cutting blade. Introduce according to this company, the service life of broach of hard alloy of this kind of double material is the 4 times above of single material broach, can make cutting time shortens half. The design of the horn that get a tip of HardCore broach is 140 ° , use TiAlN coating and form of open mode chamfer to discharge bits in order to assist. Product standards is 16mm of Φ 3- Φ , the oldest long way compares for 5: 1(is used at machining steel and cast-iron) . Be about to appear on the market inside the oldest long way compares refrigeration broach can be as high as 8: 1(is used at machining stainless steel and) of hard steel of temper by dipping in water, apply to minimum to lubricate (MQL) treatment. This company can be offerred at present suit to machine cast-iron, steel and titanium alloy (a variety of HardCore broach that hardness amounts to 50HRC) . CNC Milling
