Mapal introduces world's first MQL tool inspection system
1 min read
Mapal has introduced what it believes to be the world's first automatic tester for cutting tools used in MQL (minimum quantity lubrication) applications. This means that users of MQL technology, which Mapal says typically reduces machining costs by 10% or more, can now test tools away from their machines.
Currently most users of MQL technology inspect tools directly on the machine before each use, effectively putting the machine out of service for the duration of the inspection. With the Mapal Unitest-MQL, the tools can be fully tested and inspected away from the machine greatly reducing machine downtime.
During its fully automatic test cycle, the Unitest-MQL sprays an oil and air mixture suitable for the intended machining process onto a test surface for a fixed time. 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 it is returned to service.
The first production version of Mapal's Unitest, at Ford-Werke in Cologne-Niehl, is being used to verify the performance of the MQL tools used for engine block manufacture. Mapal says its customer reports that its specifications relating to tool design, production quality and machining times can now only be achieved with the aid of the Unitest-MQL.
