External influences and chip removal can cause the loss of certain ingredients. Thus, for the best use of Oemeta’s cooling lubricants, we recommend to use a specific additive if required. Control additives maintain an optimum level of the emulsion’s or the machining oil’s property parameters. Consequently, the performance and the machining result are ensured and the service life of the cooling lubricant is extended. Oemeta provides a range of control additives named ADDI-PROX for the maintenance and specific adjustment of properties. These are perfectly matching Oemeta’s cooling lubricants.
