Their Way: Traditional Flood Coolant

  • Fluid is cheap, but costly to recirculate, filter, clean up and dispose of
  • Fluid application makes a mess
  • Low lubricity = heat generation

Our Way: Cutting/Machining Oil with MQL

  • Quantity requires is in millilitres, not litres
  • Machining oil fluid is consumed in the process – no mess!
  • Quality lubricant decreases heat, improves tool life
  • Produces clean, dry chips with no fluid disposal/handling costs

Stop getting machining coolant all over your machine, tools, and floors.

Since 1957, Unist has been producing world-leading revolutionary solutions for metal cutting. Our MQL spray technology means you use less machining coolant which not only leaves your shop cleaner, but helps your tools cut cooler, last longer, and produce more good parts. By precisely metering and dispensing Unist Coolube® machining oil at the cutting tool/work piece interface, you greatly reduce friction at the cut and ultimately save money.

There is the OLD way which uses flood Coolants—using mineral oils mixed with water. Unist Australia eliminates the use of flood coolants and replaces it with a cost-effective alternative. We use a metal working fluid, specifically Unist Coolube®, which we refer to as an "Advanced Metal Working Fluid" or Advanced Metal Working Lubricant which is specially formulated by Unist for use with all minimum quantity lubrication systems (MQL). Our solution not only eliminates the safety hazard created due to coolant spilling over your machine tools and floor areas but also eliminates the skin condition dermatitis which operators frequently suffer from when handling coolants.

Using an advanced metal working machining oil which is applied neat (without dilution) reduces friction and therefore reduces heat. When we apply this lubricant to the cutting area, we achieve a significant reduction in tool wear. This is because our machining oil is 100% oil as opposed to being a coolant, which is 98% water and just 2% oil.
