At Greenfield, we operate a comprehensive preventative tooling management program designed to maintain turret tooling at optimal sharpness. This ensures maximum performance and consistent production of high-quality components.
Optimizing Tool Life
There is no fixed lifespan for tooling — performance depends on several key factors, including:
-
Material type and thickness
-
Punch size and geometry
-
Type of punching (full hits or nibbling)
-
Machine setup, tool lubrication, and die clearance condition
To manage these variables, every tool is regularly checked and monitored by our experienced engineers.
Predictive Maintenance
Our predictive maintenance strategy is built around precision and reliability:
-
Tracking punch and die usage (hit rate) through dedicated software
-
Conducting scheduled inspections of all production tooling
-
Monitoring burr formation on materials
-
Applying a preset sharpening threshold of 0.2 mm before burrs occur
-
Using collected data to tailor sharpening schedules to specific materials and environments
This method ensures maximum tool life, consistent part quality, and minimal unplanned downtime.
Precision Re-Grinding
Greenfield’s automatic Amada Togu-EU grinding machines on each site eliminate the risk of inconsistent grinding. Each machine precisely removes the prescribed amount of material, ensuring every re-grind is consistent, accurate, and repeatable.
