Sand blasting handling method:
On last experiment we had decided to use 3.0 bars as it shown better result. Now we had to investigate the sand blasting handling method. Instead of trying sand blasting horizontally we decided to go on with blade rod stand firm vertically and the sand blast nozzle moving up and down vertically to perform sand blasting.
No Blade Rod
Table: Test result on vertical method
The result of the experiment shown that vertical handling method had able to de-burrs all burrs on blade tips.
