Task
Replace a servo driven linear module with a more robust and reliable, cheaper maintainable system without modifying any adjacent mechanical or electrical components.
Solution
After reverse engineering the affected parts of the machine we created a synchronous belt driven carriage with robust linear guidance. We kept the original servo drive and controller and choose the pulley size to have the same displacement as with the original spindle. We also remanufactured the chutes and affected guards. Checking the load of the servo drive was certainly part of this project and led to slight optimization of moving components.
We preassembled the module in our workshop and replaced it on site in a day. After successful test production we rebuilt additional 2 machines.
