Deburring and cleaning vehicle precision components
Innovative robotic deburring cells use waterjets at up to 2,000 bar to simultaneously deburr and clean vehicle components. Plants rely on Stäubli six-axis HE robots, which are perfectly designed to handle the tough conditions in the cell.
Maschinenbau Silberhorn has made a name for itself in the development, design and production of systems used in high-pressure waterjet deburring, cleaning and electroplating. Silberhorn's most popular products include the REZ automated deburring cells, which are mainly used in the automotive industry for deburring workpieces with a technically complex geometry.
Depending on the material, the machines can debur aluminum at pressures of 300 bar and stainless steel parts at up to 2,000 bar.
Parts handling by robots under extreme conditions
The job of the robot is to handle the parts. The six-axis model picks up the waiting components, moves them along a precisely predetermined path to facilitate deburring and cleaning by the high-pressure waterjet, and then returns them to the production line. Working in the cells is a tough job for the robots. At water pressures of up to 2,000 bar, the conditions in the cell are extreme. The amount of kinetic energy just in the waterjet that bounces off the deburring part is phenomenal. When programming the course, you must always ensure that the robot's wrist never crosses the waterjet and is largely protected from side impacts.
To ensure maximum flexibility of the cells, several deburring tools can be installed in the deburring chamber, so that the only setup needed is to select the program in the control panel. All parts of the system are made of stainless steel. Depending on the size of the system, either a Stäubli TX90 HE or the larger RX160 is used. The suffix HE stands for Humid Environment and refers to Stäubli models extensively modified for applications exposed to spray water.
