Rösler’s compact RWK 6/12-2 swing chamber shot blast machine is equipped with automated workpiece handling and can easily be integrated into linked manufacturing lines, requiring very little space. In addition, the furnished digitization software package from Rösler Smart Solutions provides complete process and cost transparency and minimizes the overall personnel requirements.
The swing chamber shot blast machine can be used for all kinds of shot blast applications such as surface cleaning, de-sanding and descaling, surface homogenization and sophisticated shot peening operations. The workpieces treated in this machine include all kinds of castings and forgings, machined components, welded sheet metal parts and technical springs.
With its surprisingly small footprint, the compact shot blast machine requires little space when integrated into linked manufacturing lines. Specially prepared interfaces in the machine controls facilitate the quick connection to higher-level production control systems. A standard industrial robot handles the workpieces by placing them into the blast chamber and removing them after completion of the blast cycle. This task requires very little programming effort. A special clamping mechanism in the blast chamber holds the workpieces in place during the shot blast process.
In its standard version, the RWK 6/12-2 can handle workpieces with diameters of up to 600 mm and lengths of up to 1,200 mm. The clever dual chamber design enables the workpiece loading/unloading in one chamber, while the shot blast process takes place in the second chamber. This can almost eliminate unproductive times. The machine is equipped with two Gamma G turbines, which guarantee short cycle times and energy-saving operation. The installed power of the turbines and their placement on the blast chamber is always adapted to the respective shot blasting task. These turbines are equipped with curved throwing blades in “Y” design.
Compared to conventional turbines, the special blade form produces a significantly higher media throwing speed. This results in a 20% higher shot blast performance with a significantly lower energy consumption. Overall, cost savings of up to 25% can be achieved producing overall excellent efficiency of the entire shot blasting operation.
Another benefit of the “Y” shaped blade design is that both sides of the throwing blades can be used. This practically doubles their usable life. With a quick-change system, the throwing blades can be easily replaced without having to remove the turbine from its housing. Idle equipment times are, therefore, minimized.
The machine also has a wear-resistant design: The blast chamber is made from manganese steel and is additionally lined with easily replaceable wear plates made from a low-wearing material.
Digitization modules from Rösler Smart Solutions software package is designed to lower the operational costs and personnel requirements through intelligent process and equipment controls. At its center is the active monitoring and analysis of various machine components and process parameters.
Industries such as automotive, aerospace and medical engineering frequently demand complete documentation of the operational data to control the compliance with precisely defined and validated process parameters. With the Smart Solutions modules Rösler also helps optimize the preventive maintenance of the equipment by keeping track of the operating hours, recorded uptime statistics and the automatic release of spare parts orders.
