The equipment features 10 part stations (5-index turntable), with 4 stations designated for blasting. Springs are loaded into 2 loading stations, where servo motors compress them with controllable stroke, then transferred to waiting stations. Upon indexing to the blasting stations, pre-stress blasting is performed in the compressed state. The machine is equipped with 4 high-performance 30kW blast wheels, each aligned with one blasting station, achieving a cycle time of 10 seconds per spring. The equipment offers high process control precision and a comprehensive monitoring and alarm system, and can be integrated with robotic loading/unloading for automated production lines.
