Abstract:
A highly efficient precision grinding method was proposed for the development of typical freeform surfaces such as turbine blades. A sixaxis simultaneous grinding and polishing machine was created. The machine can polish freeform surfaces with abrasive belt grinding technology by computer numberical control(CNC). The key techniques to develop this new grinding machine are presented in detail, including multiple axes rotary spindle grinding head, NC grinding computer aided software, cooling, a scrap removal device, and other features. The experiments of grinding and polishing turbine blades were performed based on different parameters. This research provided sufficient data to confirm reasonable belt grinding and polishing parameters.
