Blanks for indexable inserts are hardened in sintering furnaces under high temperatures. This is not possible without complex cooling circuits whose flow rate must be continuously monitored, for example, to prevent thermal damage to furnaces. Reason enough to rely on equally robust and reliable flow monitors for this task. One tool manufacturer specializes in the production of indexable inserts that can be screwed or clamped into tool holders as cutting material carriers for machining metals or wood, for example. "Our production of indexable inserts runs continuously throughout the year, producing several million of these per year," explains the company's maintenance manager.
