The home of the company Gräff industrial automation is in Hennef near Cologne. The geographical location nearly the Airport Cologne/Bonn is very good however not decisive, because we deal with automatisation and programme from special machines over the hole world. We have 14 industrial- robot programers, who also work as commissionars.


Our services...
  1. Programming and commissioning of industrial robots of the companies ABB (S2, S3, S4 and S4c plus), Kuka (KR C32, KR C1, and VKR C1) and FANUC (RJ 2/3).

    We offer this for the following applications:
    • Spotwelding in Resistancewelding
    • Arcwelding with prodectiongas CO² and mixturegas (Admixture of Argon or other noble gases)
    • Arcwelding with oscillating
    • Arcwelding with seamtracking
    • Boltwelding
    • Glue
    • Seamsealing
    • Cosmetic Sealer
    • appling bitumen (for avoiding of clappering of plates and doors)
    • Applying windowsealingmass
    • Stampduffering
    • Handling
    • Pick and Place
    • Welding with all itemized welding-applications
    • duffering
    • Deburring
    • Labeling
    • Stumping
    • Messuring
    • Waterjetcutting



  2. Realizing of customerwishes and Software-installations within the KUKA KR C1, and V KR C1, FANUC RJ2 and ABB S4 systems. On these systems we are familiar with the robots downto the systemarea. We are experts and User-Tech-Programmers on the KRC 1 (VKRC 1).



  3. Realizing of Robotprogramming

    • Generation of operatingpointorders (Spotwelding, Cleaving, etc.) for "Teaching"

    • Assigning of operations to tools

    • Creation of weldingparameters and their optimization

    • Attaching of tools, guns, gripper, boltwelder, cleaveguns, burnertube

    • Monitoring and tracing of dates

    • Planing and dokumentation of all work to make

    • Creation of schedulingdata from time/way Diagrams


  4. Offlineprograming (OLP und SOP),
    Working with RobCAD,
    ABB RobotStudio and
    KUKA KR Sim Offline Programingsystem
    • Testing of reachability offline and online

    • Cellsimulation (incl. partmoving, pointassigning, Cellchoice etc.)

    • Testing of ticktime-optimization and reachability

    • calibration

    • Offlineprograming


  5. Softwaredevelopment and -installation

    • C ++, VB, Pascal Programing
    • KRL (Kuka Robot Language)
    • Creation and integration of userinterfaces and input masks
    • Realizing and programing of OPC connection with visualizationsystems
    • Softwareenhancement
      • Integration of Spot, Handling...- Pacets
      • Userinterfaces for the PHG for simplified work (Stacking, Errordisplay)
    • Parameterization of programs
    • Calibration of the systems (Messuringsystems too)
    • Interbus and Profibus integration and configuration
    • Integration of functions, that are not supplied in the seriescontroller by the manufactor
    • Hardwareinstallation
      • Hosepackets

      • Guncare

      • Organizing grippers


  6. Linesupplying and productioncontrol




  7. Optimization

    • A robot's ticktime-optimization and Productionquality-optimization belongs to our fortitude. Here we are very well able to bring our experience into the project.Jede Sekunde zählt.

    • We also support optimization of the robots or the whole line in the night or on weekends.


  8. Schooling of lines and userpersonnel

    • trainingmethodes for:
      • Robotprograming with the application mentioned above espeacially with

      • Resistance- and weldingcontrol of i.e. the companies Serra, Fase, Bosch, British Federal
      • Seam- / Weldingcontrol of i.e. the companies Nimak und Kemmpi
      • Lineleading individually for your mashine
Our customers are espeacially working in the automobileindustry and their suppliers. We do these jobs by workorders and in directionwork (based on hours).
