PROCESS FOR PRODUCING CAMSHAFT AND APPARATUS FOR MAKING THE SAME |
| 摘要 |
<p>In order to be able economically to produce longitudinal hollow body components, especially camshafts, not only with a saving in tooling and working steps but also with increased efficiency, projections or cams (6) from a hollow shaft (5) are made by high internal pressure forming in such a way that the form and/or position of the projections (6) can be shaped in several steps.</p> |
