PVD coating failures don't happen at the coater. They happen at the prep stage, or the lack of it.
Before a PVD coating bonds properly to a solid round tool, the substrate needs to be clean, activated, and consistent. Dry processes can't reliably deliver that without introducing micro-cracking.
The Vapormatt Oncilla automatic wet blasting machine was built for exactly this problem.
Fine aluminium oxide in a water cushion cleans, activates, and conditions the surface in one controlled pass. The gantry robot picks each tool by the base, lowers it into the blast stream, and processes it without touching the cutting edges. Every variable is locked. Every tool in the batch reaches the coater in the same defined condition. Not approximately. Repeatably.
The Oncilla even follows helical profiles with patented micro nozzles, delivering targeted blast streams to exactly where the coating needs to bond.
