Quaker metalworking fluidProper set-up of a padded reamer presents particular challenges for the metalworking fluid, says Quaker. The fluid is required to deliver the necessary lubrication in a sufficient film thickness and also emulsion properties that will carry away the fines produced in the cutting process. The company says it has developed a semi-synthetic fluid technology, Quakercool 7450, designed for reaming applications, that provides the required tapping performance in heavy-duty machining operations such as on automotive aluminium alloys.

Quaker claims the formulation of this metalworking fluid provides the necessary lubrication at the pad/metal interface for surface finish requirements while also maintaining efficient fines handling. It is free from formaldehyde and boron and meets HSE compliance says the company, and offers foam, emulsion and bio stability.
