Autonomous production
Race Modular
The future of the rolling bearing industry lies in the autonomous use of production machines. In very close cooperation with our customers, the Supfina Race Modular system solution has been systematically developed for the autonomous and unmanned superfinishing of rolling bearings.
All key production processes are automated and run 24/7 without an operator:
- Batch change
- Mechanical set-up process
- Tool change
- Finishing stone change in production
- Component handling
- Control through production line
The Supfina Race Modular offers all the advantages of autonomous 24/7 production without an operator:
- Higher production capacity utilization
- Faster order processing and therefore cost and time savings
- Precision and flexibility
- Increased productivity
- Work safety
- Scalability
Thanks to its integration into the IT infrastructure, the Supfina Race Modular offers flexible adaptability to the dynamic processes of the entire production line.
