B3 Tool durability

Increasing life time of micro deep drawing tools

A combined blanking and deep drawing process with and without lubricant was used to produce several 100,000 cups (Al99.5, E-Cu58, 1.4301). For the process a follow-on toll was used, which runs with a stroke rate of 200 cups per minute. The tool was measured with digital comparative holography inside the machine.
