Abstract

Abstract
Emulsifying metalworking fluids are subject to continuous development, with the purpose of meeting increasingly stringent human health and environmental protection requirements, as well as cost efectiveness advancement.
Most of the usual concentrate components are being replaced by new ones - less harmful for human health and the environment. A modern working emulsion is required to have as long a service life as possible, with as simple and as cost effective maintenance as possible. Prolongation of the emulsion's service life reduces the total quantity of waste emulsion, the need to use auxiliary means, promotes industrial hygiene, cuts down management costs, as well as overall costs, and finally advances fluid management in general. Lubricant manufacturers play an important role here: From the generation of modern fluids, to providing recommendations for the choice, system cleaning, emulsion maintenance at application, human care, and also for the used emulsion management.
The selection of a biostable fluid considerably prolongs the emulsion's service life with regard to conventional emulsions. At application, biostable emulsions do not require special maintenance, although it is well-known that improved care extends emulsion service life.
The paper provides results of testing a less human health and environmentally harmful biostable emulsion at application in various metalworking operations at several metalworking plants.
