If the workpiece is too large or difficult to move, the robot cells are designed so that the workpiece is fixed or fixed on a rotary table with CNC axis and machined with one or more robot-guided tools.

The standard robot cell shown here is designed for the machining of gravity die castings.

The workpieces supplied by the customer are picked up via a CNC rotary table with a machining position and a loading and unloading position. Loading, unloading and machining can thus be carried out in parallel.
An additional rotary axis integrated into the robot control repositions the workpiece during machining.

Five tools are mounted on a multi-tool head and are selected depending on the machining operation.
Programming is done offline, e.g. using
RobotStudio. Measurement of the workpiece is integrated into the system.

The robotic cell of the series RSP/5F/3R shown here is composed of:

• 2 robots for loading and unloading
• Positioning of the workpieces by a processing robot via CNC rotary table
• Multi-tool head for holding five tools equipped with five pneumatically driven precision spindles

The robot cell of the RSP/5F series shown here is designed for deburring and milling cast and forged parts.

The workpiece positioned on the loading table is gripped by the robot.

The workpiece is aligned and measured with the aid of a camera measuring station and demo 3D measuring probe.

After that, the workpiece is machined at a milling station with a fixed milling spindle.

The robotic cell consists of:

• Rotary table for loading and unloading workpieces with a diameter of 2,000 mm, holds up to 30 workpieces
• Milling station with pneumatic spindles for the use of burrs
• Camera measuring system with illumination and lens
• 3D probe

The fully automated robot cell is designed for deburring large-volume workpieces.

The feeding is carried out by the customer via a loading and unloading position. From then on, the workpiece is machined fully automatically.

The workpiece is positioned on a CNC rotary table for machining within the production center. The rotary table axis is fully integrated into the robot control system.

The workpiece is machined with various rotating tools such as grinding wheels or milling cutters.

Depending on the machining task, a tool change is carried out and takes place from a change magazine.

The machining is prepared by means of offline programming – e.g. via RobotStudio.

The robot is equipped with a force-torque sensor, so that an almost seamless machining of contours is possible.

Thanks to additional measurement technology, this robot cell can be offered as a turn-key solution.

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
