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.

1、制作三块相同规格的精细陶瓷剃须刀：m2.5，OD130mm，但使用不同厂家的三种不同的陶瓷片进行试验。 2．对附着在主体上的陶瓷碎片进行重新研磨。使用金刚石砂轮，是可能的并且已经做到了。3。汽车变速器差速器传动齿圈的精加工试制剃齿滚刀及切削条件； v=450m/分钟。 f=1mm/rev.、5mm/rev.，表明齿轮的滚齿精度和表面粗糙度均良好。 4．据了解，专用切削油的选择非常重要，必须考虑到切削速度、刀刃及边缘部分的切削作用。 5．数控齿轮精加工机主轴采用交流主轴电机，切削速度可达2200m/min..6．成功完成了CBN刀片剃须刀的设计和试制。 7．成功地在滚刀主体螺纹表面多层CBN切屑，并成功研制出螺纹形CBN砂轮形状的陶瓷剃刀滚刀。 8．采用螺旋形CBN砂轮精加工汽车变速器差速器传动齿圈，切削条件v=2000m/min.，f=1mm/rev.，5mm/rev.，取得成功。 9．利用m8、OD150mm硬质合金剃齿刀在大模数硬齿面齿轮上进行切削性能、切削油等方面的不同实验，使大模数陶瓷剃齿滚刀的实际应用前景成为可能。
