SAT7 2SP satellite machine for single and double shot peening of gears
This video shows a CYM SAT7 2SP satellite machine, designed for single and double shot peening of automotive gears, pinions, shafts and crown wheels. The shot is projected by compressed-air nozzles. The machine in the video works at the Scania Argentina plant.
A servo gear motor turns the table and carries the parts through four blasting stations, with two nozzles per station. A laser sensor confirms the right part is loaded, and masked clamps ensure each part rotates and protect the ground surfaces. Parts can be up to 400 mm (15.7 in) in diameter and 600 mm (23.6 in) high. The cabinet has partitions between satellites and a high-chrome steel lining above 64 HRC.
The nozzles move on the X-Z axes with servo-driven electric cylinders. Each nozzle has independent flow and pressure regulation, and the double-chamber blast pots have shot level sensors. Everything is controlled and monitored from the HMI, with alarms for any process deviation.
The machine runs two shot sizes, with a dual recirculation and classification system, and has an Almen fixture with a dual strip holder. Process stability exceeds a CMK of 1.7.
