Application of Semi-hydraulic Unloading and Composite Guide Technology in Large CNC Hobbing Machine |
| |
| Abstract: | Aimed at the problem that large CNC hobbing machine encounter creeping at low speed, a semi-hydraulic unloading and composite guide technology was put forward.The working principle of the column hydraulic unloading introduced, and the mobile location factors of CNC hobbing machine ( X axis) was analyzed.The result shows that the mechanism can reduce the difference be-tween static and dynamic friction when machine tool column moves, which provides an effective method to solve the problem of low ve-locity crawling in large machine tool. |
