GEAR SHAPING METHOD AND DEVICE AND SPIRAL BEVEL GEAR CUTTER |
| 摘要 |
<p>Bevel gear cutting is to be effected in high efficiency and at low cost. To this end, when a bevel gear is generated using an annular milling cutter 21 having a blade material 23 made of a high-speed tool steel mounted to a main body 22, the blade material 23 is coated with at least one layer of a film of a composition substantially comprising (Ti(1-x)Alx)(NyC(1-y)) (where, 0.2 </= x </= 0.85, 0.2 </= y </= 1.0), and dry cutting is performed at a cutting speed in the range from 20 to 400m/min without using a cutting oil. With this method, teeth can be generated at a greatly improved cutting speed without using any expensive tool such as cemented carbide, thereby realizing efficient production of a bevel gear at a reduced cost. <IMAGE></p> |
