[0004] The existing turbine blade grinding processing device has the following disadvantages. Since the adjustment process of the existing turbine blades during processing and grinding is relatively cumbersome, after processing one turbine blade, the staff needs to disassemble the entire turbine blade, rotate the direction and install it, and then process and grind the next turbine blade. This processing method is relatively cumbersome, which makes the equipment have certain limitations. Therefore, we propose a new type of turbine blade grinding processing device.
