John Neale Ltd is a specialist formulator and supplier of highly advanced cutting fluids.

Here is a planned way to decide what water-mix metal-working fluid would be best for you:-

1) Find out the following information:-

1. Water Hardness

2. Metals being machined

3. Existing problems - bacteria, fungi, tramp-oil, corrosion, staining, foam, scum.

4. Pressure

5. Filtration

6. After process actions - degreasing, rust preventive.

7. Irritation issues, sensitization.

8. Environmental issues, chlorine-free cutting fluid, renewable-based cutting fluid.

2) Depending on the findings specific recommendations can be made:-

1. Hard water stable soluble metal working fluid or soft water suitable cutting fluid.

2. Specific or multi application choice for cast iron, steel, aluminium, copper, brass, titanium, stainless and nickel alloys etc. Special consideration for hard metal grinding where cobalt leaching can occur.

3. Highly resistant to degradation products, tramp-oil splitting, corrosion inhibiting, low foam, low scum. The optimum balance of properties will depend on the actual operation.

4. Low foam products for high pressure, through drill, or creep-feed grinding applications.

5. Cutting fluid which will filter easily and drop fines efficiently.

6. Products which will allow for water degreasing processes, clean anneal, give inter-operation rust prevention.

7. Low irritancy products, amine-free coolant, boron-free coolant, formaldehyde-free coolant, no R43 labelling, MIT BIT and CMIT free cutting fluid.

8. Biodegradable based cutting fluid, renewable base-stocks, chlorine-free cutting fluid, ester-based cutting fluids.

3) At this stage you can see the selection of fluid is complex and customer specific. It really is worth getting in touch with John Neale Ltd to ask for advice to get optimum selection.
