Robot type PTR-S-R

Compressed air / Shot peening

The shotblasting machines with rotating satellites type PTR-S-R are designed to peen sensitive parts in singularly mode with any kind of shots (steel shots, cut wire, corundum, glass beads, ceramic beads…).

The machine is equipped with a main indexed table that permit the entrance/exit of the parts into/outo the blasting chamber. The main table is equipped with 2 or 4 satellites; each partition is divided by a wall to prevent media lekage and noise escape in the operator area. One satellite is dedicated for loading/unloading, while another one (opposite to the loading area) is dedicated to the peening process. The nozzles are driven by a robot. The number of nozzle is defined according the loading volume, the production rate and the complexity of the piece geometry. This machine is usefully for manual loading/unloading operation but it can be also equipped with an automatic handling devices according the process line request (2-axis gantry, robot…). Pressure technology is installed on such equipment with a double pressure vessel in order to guarantee the shot flow without interruptions. Each pressure vessel exit is equipped with Magnetic Valves for shot flow check. This machine is used for surface shot-peening. The machine can be equipped with up to three robots for peening
