Monitoring metalworking fluids is a critical process in optimizing performance and extending fluid life. The necessity and methodology for analyzing fluids has remained virtually unchanged for years, yet there was still no way to easily record the data, share it with other departments or suppliers, and measure fluid concentration. Though new solutions enabled by digital technologies are emerging on the shop floor to help with tooling, machine tools or CAD/CAM services, this was not the case for monitoring metalworking fluid performance. Quaker Chemical Corp. recognized the need for innovation to help its customers monitor fluid performance. As a response, the Quaker team developed CoolanTool, a mobile app that addresses the needs of technicians that use metalworking fluids in their machining processes.
