ROI<2 years
75% lower personnel costs
30% abrasive material saving
24/7 industrial grinding cell
PROBLEM & DEFINITION
SHORTAGE OF SPECIALIST PERSONNEL
- grinding welding spots
smoothen surface to the micrometer range - generate structure-free surface pattern
- large variety of parts
Material: Steel
SOLUTION
ACTIVE ORBITAL KIT 201
A complete package that has a variety of uses, based on Active Compliant Technology combined with a robot-friendly eccentric sander, which delivers the following benefits:
- consistent high quality
- tolerance compensation
- easy jobmodulation
INITIAL SITUATION
Both, HASE and the customers greatly value the perfect and high-quality look of the stoves. The grinding process during production is vital for the end quality. A large order book and a serious shortage of qualified grinding personnel on the labor market were critical for choosing automation.
THE PROCESS
In order to achieve the perfect stove, the steel parts have to be grinded perfectly. Even the smallest defects are visible in the 25-micrometer high-temperature paint that is later applied. The rough grinding and finesse sanding therefore have to deliver the desired result.
THE AUTOMATION
The process was automated using a grinding cell together with the integrator SHL AG. The cell contains a robot which grips the manually provided parts. First, they are passed to a belt grinder for basic processing in order to nally get the perfect nish and the required structure-free surface pattern from the FerRobotics AOK eccentric sander. The cycle time is 6 minutes.
THE RESULT
-
solution for the shortage of specialists by saving personnel
- high-quality surfaces and reproducible quality
- optimization of the abrasive used
