used machine

KUKA KR16 L6 ARC-C robotic welding machine together with the PO-2t6m-01 rotary positioner was commissioned in 2017 and its purpose was to very precisely weld gates and fence spans, but it can also weld various types of structures that fit within the range of the rotary positioner. The welding station includes a robotic arm built in 2009, which was previously only used for testing. The whole thing has only worked for 50 hours.

The KUKA KR 16 L6 ARC-C robotic welding system is equipped with:
– welding robot: KUKA KR16 L6 ARC-C
– controller: KUKA KR C2
– rotary manipulator: PO-2t6m-01
– current power source: FRONIUS TransPuls Synergic 4000 CMT R
– software: KUKA System Software (KKS)
– torch cleaning device: TBi BRG-2-ES-DAE
– wire feeder: FRONIUS ROBACTA DRIVE CMT
– track

The rail-moving KUKA KR16 ARC industrial robot with a reach of 6 m allows excellent precision and superior weld quality to be achieved, even in hard-to-reach areas. All 6 axes of the machine are driven by an electromechanical system with brushless AC servomotors to guarantee the user excellent dynamics combined with process reliability. The robot is operated using a KUKA KR C2 controller with many useful functions, significantly increasing the productivity and efficiency of the machine.

During automated welding, dynamic and accurate feeding of the welding wire is very important. For this purpose, a FRONIUS ROBACTA DRIVE CMT feeder is placed directly on the welding torch body, which supports all machining processes and ensures precise feeding of the electrode wire. When the torch becomes contaminated, a special cleaning device TBi BRG-2-ES-DAE cuts off the wire tip, sprays the torch head in an enclosed spray chamber with anti-splinter fluid and removes the spatter through the rotating reamer.

In order to perform welded joints, the KUKA robotic welding station is equipped with a PO-2t6m-01 manipulator capable of rotating parts with a maximum weight of 2 tonnes and a length of 7 metres. The device consists of a coupler, a geared motor, a reaction arm, a control cabinet, a sensor mounting unit and two bodies made of welded sheet metal in which positioner shafts with bolted discs have been placed. Attached to the discs is a rotary table centred by means of pins inserted directly into holes in the positioned shafts.
