SUCCESS STORY AUTOMOTIVE State of emergency in the cell
Task Depending on the material, the machines can Customer benefits : deburr aluminium at pressures of 300 bar ■■ Short process times Deburring and cleaning vehicle precision and stainless steel parts at up to 2,000 bar. ■■ Easy deburring of hard-to-reach areas components ■■ Highly reliable under extreme conditions Solution ■■ Deburring and cleaning in one step Innovative robotic deburring cells use waterjets at up to 2,000 bar to simultaneously Parts handling by robots under extreme debur and clean vehicle components. Plants conditions rely on Stäubli six-axis HE robots, which are perfectly designed to handle the tough The job of the robot is to handle the parts. conditions in the cell. The six-axis model picks up the waiting components, moves them along a precisely Maschinenbau Silberhorn has made a predetermined path to facilitate deburring name for itself in the development, design and cleaning by the high-pressure waterjet, and production of systems used in high- and then returns them to the production line. pressure waterjet deburring, cleaning and Working in the cells is a tough job for the electroplating. Silberhorn’s most popular robots. At water pressures of up to 2,000 products include the REZ automated bar, the conditions in the cell are extreme. deburring cells, which are mainly used in the The amount of kinetic energy just in the automotive industry for deburring workpieces waterjet that bounces off the deburring with a technically complex geometry. part is phenomenal. When programming the course, you must always ensure that reach locations such as deep drill-holes and overpressure unit.

All parts of the system are made of stainless steel. Depending on the For the robots, it is and remains a real size of the system, either a Stäubli TX90 HE endurance test. The machines are often or the larger RX160 is used. The suffix HE expected to function perfectly for years in stands for Humid Environment and refers their stainless steel cells, working to a 3-shift to Stäubli models extensively modified cycle under 100% humidity and constant for applications exposed to spray water. exposure to spray water. The HE robots from Stäubli are the only way to guarantee Customer benefits high availability and process reliability under these conditions. Deburring and cleaning in one step The HE models are designated protection Deburring with a high-pressure waterjet has class IP65 as standard, which can be two key advantages: even in difficult-to- further enhanced by the use of a Stäubli
