Multi-axis NC Machining Process Improvement of High Precision U-shaped Thin-wall Aluminum Bearing Parts

The thin-wall part processing characteristics were analyzed. Taking a low-volume high-precision U-shaped thin-wall aluminum bearing part as example, special fixture was designed to achieve partial five-axis machining transferring three-axis machining technology, so cost was saved and technical direction was provided for the enterprises to rational use of high-end equipment. A special tool was designed. And shock absorption and vibration measures were provided to improve the five-axis machining technology, so pro-duction efficiency was improved and scrap rate was reduced. The practice has proved that process improvement measures are practical and efficient in dealing with thin-wall parts processing.
