Which Of Excision's Water Soluble Coolants Should I Use?

This is part of a series on Lubricants and Coolants. 

Excision is the leading supplier of coolants for the metal working industry in Australia, focusing on innovative synthetic coolants to reduce our reliance on mineral oils. The coolants they offer covers a wide range of uses, so how can we differentiate based on our requirements? This quick and nifty guide can help you navigate the slippery world of water soluble coolants.

What’s The Difference Between XDP1000, XDP2000 and XDP3000?

Fun fact: BST Group has sold over 35,000 litres of XDP1000 and XDP2000, contributing to their titles as best-selling coolants from Excision. Selecting between the two comes down to the material you’re working with, how you machine it, and how you apply it.

XDP1000

A soluble oil, made mostly from mineral oil with a soluble package that allows it to emulsify with water. When mixed with water, it goes milky white due to its high oil content. Its high lubrication properties allows for machining aluminium and yellow metals such as copper and brass and their alloys. It must be diluted in water with hardness between 50 to 500 ppm of CaCO3. Concentrate must be added to water and not vice versa. The application concentration could be between 5% to 6% for light duty operations and between 8% to 10% for heavy-duty ones. 

XDP2000

 A semi-synthetic oil consisting of a small amount of mineral oil, the XDP2000 is a cleaner alternative to the mineral heavy XDP1000. When mixed with water (between 4-12%), the XDP2000 will appear opaque and slightly yellowish as it only has a smaller content of oil. The ideal concentration must be determined according to the complexity of the operation and water hardness. It can be used for machining aluminium and ferrous alloys to minimise the drag of coolant per piece.

We have covered a more detailed comparison between the XDP1000 and XDP2000 in our previous blog here.

How Do I Decide Which Coolant Suits My Application?

Choosing the right coolant depends on your specific application needs. Here’s a quick breakdown:

Neat Oils

• Best for severe applications like tapping, broaching, deep drilling, and gear cutting.
• Offers high lubrication with minimal cooling.
• Provides excellent corrosion protection.
• XDP120 is a neat cutting free mineral oil used especially in the area of minimum quantity lubrication (MQL), used primarily in machining aluminium and aluminium alloys and non-ferrous metals in general.
• XDP900 is a high-performance neat oil for medium and severe cutting applications, such as for middle to high alloyed steel, aluminium, copper and brass.

Soluble Cutting Fluids

• Most common on the Australian market.
• Good lubrication and corrosion protection with decent cooling power.
• Ideal for aluminium and metals needing strong lubrication.
• XDP1000 is a refined mineral based cutting fluid suitable for machining materials like steel, copper, brass and their alloys.
• XDP2000 is a semi-synthetic cutting fluid for ferrous metals, aluminium and aluminium alloys.

Semi-Synthetic Cutting Fluids

• Combines oil and synthetic esters for lubrication.
• Cleaner with excellent lubrication and cooling efficiency.
• Reduced drag-out lowers consumption and increased resistance to foaming.

Neo-Synthetic Cutting Fluids

• Emerging trend in metalworking.
• Based on highly refined synthetic polymers.
• Clear like water, with excellent lubrication and cooling power.
• Very high stability, no smell or bacteria risk, and fewer additives.
• You can preorder XDP3000, a fully synthetic water soluble coolant here.
