据Barber—Colman 公司发言人指出,应用氮化钛(TiN)涂层新工艺制造齿轮刀具,可使插齿刀使用寿命增加2～3倍,齿轮滚刀寿命增加高达6倍.在相同条件下,齿轮刀具的齿顶、转角及齿侧磨损量仅为无涂层刀具的三分之一.切削试验也表明,涂层立铣刀的切削速度和耐用度较普通铣刀都有显著提高.芝加哥Latrobe 公司试验结果表明:TiN 涂层钻头两次刃磨间的使用寿命比普通刀具延长百分之五十左右。佛蒙特丝锥板牙公司在钻头钻削寿命对比试验中,对4340合金钢分别采用了三种不同的切削速度。在56呎/分的正常速度下,涂层刀寿命为普通刀的330%;速度增加60%时,普通刀寿命急剧下
According to a spokesman for Barber-Colman, gear tooth cutting tools are manufactured using a new process for titanium nitride (TiN) coating, which increases the service life of gear hobs by two to three times and increases the gear hob life by up to six times. Under the same conditions , Gear tooth tips, corners and flanks wear only one-third of the number of uncoated tools.Cutting tests also show that the coating end mill cutting speed and durability than the average milling cutter has significantly improved. Test results of Latrobe Company in Chicago show that the service life of TiN coated drill between two sharpening mills is about 50% longer than that of ordinary tools. Vermont Taps Company drill bit life comparison test, the 4340 alloy steel were used in three different cutting speeds. At a normal speed of 56 feet / minute, the coated knife life is 330% of the normal knife; when the speed is increased by 60%, the average knife life is sharp
