When a major fortune 500 aerospace company, who had built their reputation on being “dependable ,“ selected Guyson to design and build a custom grit blaster for batch processing gas turbine blades; its engineering team realized that this was something truly unique. The customer was involved throughout the design of the system and was impressed with how Guyson was able to completely blast the blades in one operation.
Guyson developed a “SP-10” semiautomatic Grit blast system using its precision 150/16 reclaim system with vibrator and heater installed on the media hopper to keep the fine 240-grit alumina oxide flowing. The six Guyson guns are mounted to the gun oscillator that moves at a programmed rpm, adjustable on the HMI. The table speed is also adjustable through the HMI and can easily handle the large 34”-dia. basket and its 100-lb. load.
Guyson’s new vertical door design provides the protection required to comply with the maximum 80-dBA noise level requirement while also making the loading and unloading of the basket segments a breeze.
The secret to being able to completely blast the blades is the segmented polyurethane coated basket, according to the company. This basket was custom engineering to prevent part on part impingement and masking .
