Robotic deburring station
RSP/3S: Machining of pressure casting / steel casting
The robotic deburring of die parts can be achieved with a variety of tools. Above all, rotating power tools such as milling burrs and grinding pencils, grinding flap discs or brushes are used.
Tools are selected depending on the requirements of precision, the materials, the surface and the amount of material which has to be removed. Either the tool or the workpiece can be guided during machining.
- integration of different tools in three pneumatically powered milling spindles and a brush spindle using a turret
- tool changing time: 0,4 s
- machining of the programmed curves in the geometrical order
- very short processing paths
- integration of up to four tools
- integration of a 3D measuring sensor for the calibration of complete workpieces or individual contour elements checking the position of the workpiece during processing
- increase of the lifetime of tools and improvement of the surface when deburring due to a spray nozzle installed on the tool turret
Precise and defined deburring is decisive e. g. for the machining of cylinder heads as die cast parts. The deburred edges should be 0.3 to 0.5 mm (0.01″ to 0.02″) wide to guarantee a maximum size of the sealing surfaces.
Special milling tools were developed to realize with aluminum these uniform and narrow trimmed edges reliably. The milling tools have a long lifetime and are designed in that way that the penetration into the workpiece is limited.
For the programming of the robot, offline software is included in the scope of delivery. It selects the drawing data and assembles the curves which have to be deburred as radii and lines.
