特点:
1、滚刀用优质硬质合金刀片焊接制成,采用径向负30°前角,直槽,渐开线基本蜗焊,切削刃为平面曲线,结构可靠,切削稳定。
2、可滚切硬度为HRC45-64的各种淬硬齿轮。*用于高精度齿轮磨前的半精加工和低精度齿轮的精滚加工,A*可直接滚刀GB10095-88七、八级精度的淬硬齿轮。被加工齿轮的表面粗糙度达Ra0.63-1.25微米。一次刃磨后的滚切长度为50-100米。
FEATURES:
1、 The blades of hobs are made of excellent carbide alloy and welded on rake surfaces.Hobs are designed of 30° negative rake angle, straight flute,involute base worm and plane curve for cutting edge,They are reliable on structre and steady in process.
2、 Various hardened gears of HRC 45-64 can be hobbed.Class A hobs are suitable for semifinish of pregrinding high precision gears and finish hobbing of low accuracy gears.Class AA hobs can hob the hardened gears of class 7 and 8(GB 10095-88(.The surface roughness Ra 0.63-1.25um can be obtained for tooth suface of gear.The tool life for one sharpening is 50-100m.
