When the different type cutting tool that evaluates a specific treatment to use, normally need considers the manufacturing level of job shops. The use that the center gets is the hole that in the end of workpiece ministry getting cuts to have specific aperture, deepness and figure, use at carrying on the bearing of lathe or grinder is top. Before undertaking to all slightness workpiece turning or grinding are machined, must have central opening beforehand auger cut treatment. Type of the most popular two kinds of center getting is high-speed steel center is gotten and center of integral hard alloy is gotten. Drilling tool of high-speed steel center has taller cost effectiveness, suit production lot quite commonly not quite, old to having long way is compared (L/D) the workshop that workpiece undertakes turning or grinding machines. Every month may need this kind of job shops only use up a few center getting. Center of integral hard alloy gets the price more costly, the workshop that machines possibly to large quantities of quantities has appeal more, this kind of broach can undertake machining with higher cutting rate and feed rate, can acquire longer cutting tool life. However, the center of these two kinds of types is gotten in change when tatty broach, must undertake some kind is measured, cut appropriate deepness with making the bit that changes newly can be gotten (this kind is measured the likelihood uses instrument of cutting tool preliminary adjustments or detect in treatment device is finished) . For example, the humeral department that to ensure the emery wheel of grinder won't affect work or a few otherer feature, cause workpiece to discard as useless thereby, the central aperture deepness that carries a provision in whole treatment process is crucial. Of new development of Taiwan Nine9 company but center of type of dislocation razor blade is gotten can replace two kinds of afore-mentioned broach, because when broach changes a knife, should not need to undertake metrical, because this shortened greatly,treatment assists time, fit the manufacturing environment of efficient treatment very much. This company rolls out " I-center " broach occupies the first saying is industry pioneer but center of type of dislocation razor blade is gotten, it is successful of broach of hard alloy of ground general whole get cut function advantage and but the repeatability of high fixed position of dislocation cutting tool and change a function quickly compositive arrive one case. This kind of new-style broach suits all sorts of pair of component (like transmission, axis of control of crankshaft, sport) undertake big batch turning or grinding are machined. I-center center is gotten use can offer two to get the standard bit that cuts cutting blade. The fixed position that bit machines by the knife handle that matchs to it with two sells fixed position, undertake tightening solid through bolt of head of a wintersweet. The precision of axial fixed position between bit cutting blade and cutting blade is 0. 05mm, precision of radial fixed position is 0.
02mm, so tall fixed position precision makes bit dislocation or change need not undertake metrical afresh again after bit. I-center knife handle uses the tall alloy steel with hard temper by dipping in water to make, set inside cooling passageway, the point of a knife that can carry high-pressured cooling fluid bit is in. This kind of design conduces to raise cutting speed and prolong cutting tool life, can form in order to prevent at the same time " bird's nest " of form cut bits to coil. I-center center gets every bit get a needle to have two cutting blade, design mouth of bits having a platoon, can promote a bits. This kind of design can machine the high quality aperture with a smooth hole wall, because overheat arises to accumulate bits tumour and cause collapse damage,still conduce to the point of a knife that avoids bit (this is the failure mode with central the commonnest getting) . I-center razor blade uses the design of chamfer of 2 effective knives, offerred treatment aperture range is 2 - 10mm. The standard figure of bit includes ANSI 60 ° , DIN332 Form R and DIN332 Form A+B (also can offer special appearance bit) . Bit uses the matrix of K20F hard alloy that machines a design technically for central aperture and TiAlN coating. This kind of broach suits to get very much cut treatment steel of cast-iron, carbon / alloy steel, aluminous / aluminium alloy and copper / copper alloy. CNC Milling
