The adjustment procedure of this machine was complex and difficult to understand. Together with local engineers we found out how to improve the adjustment procedure.
The adjustment time was reduced from 12 times 3 hours, off-line, till only 20 minutes in-line.
Average product disalignment errors were reduced from 0.5 till 0.0 mm. Standard deviation on disalignment errors were reduced from 0.3 till 0.05 mm.
- Downtime during adjustment and readjustment reduce by 36 hours.
- Yield increase by 4%.
