Advanced 3D scanner robot for Danfoss joystick manufacturing

Danfoss Power Solutions has invested in an advanced 3D scanner robot for its joystick manufacturing lines in Nordborg, Denmark. The new device is boosting inspection routines by measuring component dimensions to micron-level precision, providing customers with higher product quality.

Danfoss Power Solutions’ Nordborg facility manufactures thousands of joystick variants for off-highway vehicles, such as forestry machines, harvesters, cranes, tractors and more. With the new 3D scanner robot, operators can tell immediately if a joystick component is within specifications. This capability has eliminated the need to outsource time-critical metrology requirements to a third-party coordinate measuring machine technology provider. The investment is thus saving considerable time and providing greater in-house control over the manufacturing process.

Abel Dukai, mechanical engineer in the company’s Connect & Controls Solutions business unit in Nordborg, is leading the 3D scanner project alongside his colleague, production technician Grzegorz Leonhard. “The scanner is so fast and easy to use that we can literally verify component dimensions while we manufacture, which is not possible with CMM technology – states Dukai -. We now know immediately whether part dimensions are 100% identical to the computer-generated design files, so the 3D scanner has taken our quality testing capability to a new level“.

Dukai adds that he was not dissatisfied with the third-party metrology specialist and will continue to use the company for tasks where speed is less critical. The GOM 3D scanner robot uses narrow-band blue light to measure up to 12 million points on the component surface within a few seconds, subsequently creating a 3D image. Colleagues at Danfoss Power Solutions then compare this image to the original CAD file.

According to Leonhard, the scanner offers micron-level precision, down to 0.007mm: “We are talking extreme accuracy. And it can even scan highly complex shapes and forms. It’s an incredible technology that’s already gaining prevalence in the automotive industry. I’m glad we now have it on board, too”.
