Process-Safe, Fully Automatic Shot Peening
Small metal workpieces can be shot peened in bulk on tumblast machines, however, this method does not provide complete process safety. RDS Mini shot peening systems are designed to handle single springs - which is a prerequisite for process-safe shot peening - in a continuous operation (longitudinal, rotary through-feed principle).
Blasting in through-feed operation is simple and safe; it allows part tracking and is ideally suited for automatic production lines. Adjustable parameters ensure defined processing in uniform and repeatable quality. With suitably adapted loading and unloading devices, the shot peening process can be integrated into continuous production lines.
The springs are fed to the machine individually on a straight-line conveyor and then move through the blasting zone. Axial movements are effected by cams attached to chains.
Inside the blasting zone the springs are properly guided by adjustable baffle plates which also serve to focus the blast stream on the workpieces for optimal exposure within the “hot spot” of the blast pattern. The parameters of the shot peening process, such as shot quantity, blast wheel speed/throwing velocity, the speed at which the workpieces rotate and the dwell time, can all be regulated to suit the specific workpiece. It is this definition of all treatment parameters that ensures process-safety at all times.Peripheral equipment for automatic loading and unloading of workpieces can be adapted to suit specific needs, i.e. separation of bulk loads / single workpiece transport or straight linear travel of single workpieces.

The blast wheel is the heart of the blasting machine, as the choice of blast wheel determines the power output and the economics.
This machine is fitted with U70x380 Universal (direct drive) shot blast wheels as standard. The Wheels are highly flexible, compact and have rotation in both directions.They provide perfect blast cleaning results and highly convenient servicing features for all heavy duty and foundry applications.
The U Blast Wheels are high capacity blast wheels with maximum energy efficiency. Their rugged design means that maintenance is easy, and the special and highly wear resistant cast alloy liners ensure minimum wear and maximum service life of the blast wheel.
