A Research on Development of Fine Ceramics Shaving Hob

1. 制作了m2.5、OD130mm三把规格相同的细陶瓷剃须滚刀，但采用不同厂家的三种不同的陶瓷片进行试验。重新研磨附着在主体上的仪式芯片。用金刚石砂轮，是可能的，已经做到了。汽车传动差动环齿在试制剃齿刀和切削条件下的精加工v = 450米/分钟。f = 1毫米/牧师。5毫米/牧师。结果表明，齿轮的滚齿精度和表面粗糙度均较好。众所周知，选择专用切削油是非常重要的，因为它与切削速度、刀片边缘和边缘部分的切削作用有关。5 .数控精加工机床主轴采用交流主轴电机，可将切削速度提高到2200m/min。用CBN芯片设计并试制了剃须滚刀，取得了成功。7 .在滚刀主体螺杆表面成功制备了多层CBN切屑，并在此基础上成功研制了螺旋形CBN砂轮形状的陶瓷剃齿滚刀。车组形CBN砂轮精加工汽车传动差动环齿，切削工况v=2000m/min。f = 1毫米/牧师。5毫米/牧师。他成功了。通过对m8、OD150mm硬质合金剃须滚刀在大模数淬火齿轮上的切削特性、切削油等进行不同试验，使大模数陶瓷剃须滚刀在实际应用中的前景成为可能。

1. Three pieces of fine-ceramic shaving hobs with the same specifications: m2.5, OD130mm, but three different ceramic chips which were applied by different maker, were made for trial.2. Regrinding of ceremic chips which were attached on the main body. with diamond grinding wheel, is possible and already be done.3. Finishing of differential drive ring-gear for automobil's transmission with trial-made shaving hob, and with cutting conditions; v=450m/min. f=1mm/rev., 5mm/rev., shows that both hobbing precision and surface roughness of gear are good.4. It is known that selection of cutting oil for exclusive use, which has to be concerned with cutting speed, cutting action of blade's edge and margin part, is very important.5. Using of AC spindle motor for main spindle of NC gear finishing machine made it possible to rise cutting speed up to 2200m/min..6. Design and trial-manufacture of shaving hob with CBN chips were done, successfully.7. Multi-layer on screw surface of hob's main body with CBN chips was succeeded, and then development of ceramic shaving hob in the shape of screw shape CBN grinding wheel was done successfully, too.8. Finishing of differential drive ring-gear for automobile's transmission with crew shape CBN grinding wheel, and with cutting conditions: v=2000m/min., f=1mm/rev., 5mm/rev., was succeeded.9. The prospect of large module ceramic shaving hob to be used in practice be come possible, after different experiments about cutting characters, cutting oil, etc. with using of m8, OD150mm carbide shaving hob on large module hardened gear.
