Chongqing Extreme Grinding Processing Technology Seminar

On July 30th, the highly anticipated “2020 Extreme Grinding Processing Technology Seminar” ushered in the registration day. This meeting is the first large-scale event held in my country’s superhard materials industry since the epidemic. In response to the current domestic and international epidemic situation and Chongqing’s local prevention and control requirements, the organizers of the conference will ensure the health of the delegates during the conference in accordance with the basic principle of “internal control and external prevention”.

Research on the deformation behavior of CNC abrasive belt grinding of integral blade disc

In the grinding of the blade surface of the whole blade disc, the thickness of the thinnest part of the blade is less than 1 mm, which is a typical thin-walled weak rigid part. At the same time, due to the narrow channel between the blades of the whole blade disc, it is difficult to design a tooling fixture that balances the grinding positive pressure for the grinding object, so that the workpiece undergoes weak rigid bending deformation of the ground part under the action of the grinding positive pressure.

Grinding process analysis of integral blade disc CNC abrasive belt

The grinding process of the abrasive belt on the blade surface of the integral blade disk is shown in Figure 2: The contact rod of the grinding head forms a constant angle φ with the surface of the workpiece, and the contact wheel supports the abrasive belt and clings to the integral blade under the action of the grinding contact pressure Fa The disc blade profile; the belt drive roller drives the belt at a constant linear speed vs. at the same time, the grinding head performs a feed motion at a speed vf to realize the grinding of the belt on the blade surface.
