While there are many factors that affect the life of a cutting fluid, such as dilution control, tramp oil, top up rates etc. the key to ensuring maximum sump life from any fresh fill is machine cleanliness.

Why Clean?

During use, machine tool fluid systems become contaminated with tramp oil machining debris, hard water soaps etc. which can be found on the sides and bottoms of tanks. These deposits are ideal breeding grounds for both bacterial and fungal infections and eventually become “biomasses” that can shorten fluid life.

It is therefore essential that when any particular fill of cutting fluid has been identified as reaching the end of its effective life, that the system is thoroughly cleaned and disinfected. Simply pumping out and re-filling is not a cost effective alternative to this recommendation.

Even where cutting fluid condition appears to be good, with no oblivious symptoms of degradation, good working practice dictates that fluid systems benefit from annual maintenance which minimises the risk of unplanned downtime and ensures safe working conditions for operators.


As with most jobs preparation is paramount when cleaning a machine tool. Prio...

All cutting fluids have, to a greater or lesser extent, the potential to cause health issues for machine operators. These risks are based on the external (skin) or internal contact involved in machining work; including the touching of parts and tooling, being splashed by the fluid, having mist settle on the skin or via the inhalation of mist.

The key to minimising this risk is the full evaluation of the machining operation; this process starts with the selection of the most suitable cutting fluid.

Considerations when choosing an operator friendly cutting fluid are:

  • Does the fluid contain skin sensitisers?
  • Does the fluid contain formaldehyde release biocides?
  • Is the fluid labelled as a skin irritant?

If the answer was yes to any of the above, you may wish to consider an alternative.

Whilst there are many other factors that affect overall safety, the selection of an operator friendly cutting fluid is a good starting point.

It must be remembered however, that a cutting fluid must be able to cope with the challenges of operating in an environment where micro-biologic contamination is the norm. Operator friendly cutting fluids must therefore be capable of resist...

A glossary of common terms used in the lubricants industry, we hope you all find it informative. Bookmark it, you’ll probably need it someday.

ABRASIVE WEAR : Wear between two surfaces in relative motion due to particles (three bodies) or
surface roughness (two bodies).

ABSOLUTE VISCOSITY : Term used interchangeably with dynamic viscosity to distinguish it from kinematic viscosity. The SI unit of absolute viscosity is the poise, however, is generally reported as centipoises (cP).

ABSORPTION : The process by which one substance draws another substance into itself, i.e. sponge absorbing water.

ACCUMULATOR (HYDRAULICS) : A device in which hydraulic fluid is stored under pressure in a system to be used as source of fluid power.

ACID : A compound containing Hydrogen, which can be replaced by a metal, forming a salt. In grease manufacture, Fatty Acids are used, which form a specific type of salt, known as soap. (See Definition of Soap).

ACID AND BASE NUMBER : An indication of the amount of free acidic or alkaline materials in a petroleum product. These materials may be either inorganic or organic. The acid number is the weight in milligrams of potassium hydroxide (KOH) re...

Electronics manufacturers and maintenance specialists have a simple new way to reduce their environmental footprint with the launch of innovative air duster and freezer spray products by UK firm ROCOL®.

ROCOL’s ECO-LOGIC® Air Duster and Freezer Spray products provide the assurance of low global warming potential (GWP). Until now, non-flammable air dusters and freezer sprays based on hydrofluorocarbon (HFC134a) technology have been manufactured to offer zero ozone depletion potential (ODP) but their effect on global warming has been ignored.

By utilising a new patent-pending propellant ECO-LOGIC offers both low GWP and an ODP of zero to offer enormous advantages compared with HFC134a based products. Using data from the Intergovernmental Panel on Climate Change, HFC134a has a GWP which is a staggering 1430 times higher than CO2 – the GWP for ECO-LOGIC Air Duster and Freezer Spray is just 6 times greater than CO2.

“The environmental benefits brought through our innovation with ECO-LOGIC products are outstanding when you put the GWP figures into perspective,” says ROCOL UK sales director Brendan Kendrick. “Replacing four cans of traditional non-flammable freezer spray or seve...
