Robot chamfering machine for tube industry PROVEA, which specialises in designing and manufacturing machines for the tube industry, has introduced its latest project – a robot chamfering machine. The robotic unit was first shown during the recent 2016 Tube Düsseldorf fair. The RU series is made to process external and internal chamfer or deburring (after a cutting process, for instance). TheRUseries is able to provide homogeneous chamfering despite a lack of roundness and co-axiality of the tube. High accuracy, repeatability and productivity are the main advantages of the RU series. The robot trajectory is adapted to the product (shape and size), so there is no need to change tool when changing the product shape. The range of product is large with the same machine and the same tool (from 10mm up to 300mm overall). The RU series also provides multiple integration opportunities: straight the same time and can be square, rectangular or oval. The operator enters the data on the touch control panel (inside and outside tube diameters and shape, number of rotations, step, depth, mill size and speed). Rotation speed of the mandrel is pneumatically controlled. The tube is taken by the pliers and brought to the removable stop as a reference position. After being detected against the stop, the jaws are closed in order to centre and hold the tube during the process. Once the tube is clamped, its position is guaranteed in the working axis. The stop moves down and the robot starts its cycle. During the process, the tube remains still thanks to the pliers. The mandrel starts a few milimetres away from the tube and smoothly penetrates into the tube during the process. This provides a clean, regu- lar and repeatable chamfer.
