Mapal MQL Cutting Tools Are Automatically Tested and Inspected Away from the Machine

Author / Editor: Eric Culp / Jürgen Schreier

The Unitest-MQL automatic tester for cutting tools used in MQL (minimum-quantity lubrication) applications, introduced by Mapal Präzisionswerkzeuge Dr. Kress KG, is believed to be the world’s first such test system. Users of MQL technology can fully test tools away from their machines on this instrument, meaning that tool inspection need not effectively put a machine tool out of service.

During its fully automatic test cycle, the Unitest-MQL sprays an oil-and-air mixture suited for the intended machining process onto a test surface for a fixed duration. The spray pattern for each of the cooling-duct bores for the tool under test is then examined, and compared with predetermined evaluation criteria. If the criteria are not met, corrective action, such as cleaning or adjusting the tool, can be taken before returning the cutter to service.

The Unitest-MQL is a very new development, but the first production version is in service now, being used to verify the performance of MQL tools employed in engine block manufacture. The Ford facility has reported that it considers that its specifications regarding tool design, production quality and machining times can be achieved now only with the aid of the Unitest-MQL.
