International Trade Fair for Die Casting: Technology, Processes, Products
16 - 18 January 2024 // Nuremberg, Germany
The robot deburring of aluminium castings can be realized with the help of various tools. The main tools used are rotationally driven tools such as milling and grinding pins, abrasive flap discs or brushes.
The selection of the tools depends on the accuracy requirements, the material, the surface and the amount of material to be removed. During machining, either the tool or the workpiece can be guided.
When machining die-cast cylinder heads, for example, precise, defined and secondary burr-free deburring is crucial.
The deburred edges should be 0.2 to 0.4 mm wide to ensure maximum size of the sealing surfaces.
Special milling tools have been developed to reliably produce these uniform and narrow deburring edges for aluminium. The milling tools guarantee a long service life and are designed to limit penetration into the workpiece.
Offline software is supplied for programming the robot, with which drawing data is tapped and the curves to be deburred are assembled as radius and line elements.
- Mounting of different tools in three pneumatically driven milling spindles and one brushing spindle via tool turret head
- Tool changing time: 0,4 s
- Execution of programmed curves in geometric order
- Shortest machining paths
- Integration of up to four tools
- Calibration of complete workpieces or individual contour elements for programming and checking the workpiece position in the process via integrated 3D measuring probes
- Increased tool life and improved surface finish during deburring by wetting with liquid from a spray can attached to the tool turret
