With virtually all machine shops scrutinising costs in the current economic difficulties, the effective filtration and recycling of cutting fluids is today a much greater priority. Unfortunately the very nature of cutting metal on machine tools leads to the ingress of contaminants such as chips, tramp oil, grease, dirt and dust into the cutting fluid. If left, this situation can lead to the formation of bacteria and fungus, which is not good for the ongoing health of the coolant, or the operator. In order to reuse the cutting fluid it needs to be cleansed of impurities using filters and separators. Today, there are a number of new innovations designed to automate the task and provide ongoing savings for the end user.

For instance, the basis of Accustrip coolant filtration products (available in the UK from MacInnes Tooling) is a patented oil separation system - essentially a mechanical system with no moving parts that requires no external energy to operate. The system extracts 99% of all tramp oil from the coolant in a process that requires no more than 30-40 minutes sedimentation time to draw the tramp oil to the surface ready to skim.
