A coolant is a mineral based cutting fluid which is mixed with water. For decades, people have been using coolants to remove heat for various metal cutting operations with amazing benefits as explained below.
Improving part quality
Using cutting fluids reduces heat and friction. Removing the heat ensures that the work piece does not expand when carrying out machining operations. Such expansions could result to size variation and could damage the microstructure of the material as well.
Reduces the Tooling Costs
The proper use of cutting fluids improves the lifespan of tools which reduces the tools’ maintenance costs. In turn, the increased tool life reduces the need for tool replacements and downtime and decreases the labor costs. By using coolants, you will spend less on labor and tool maintenance.
Increases the cutting speeds and feeds
During a machining operation there is usually friction and heating, coolants reduce this. Their use allows high feeds and speeds that help to attain optimal cutting conditions.
Improve surface finishes
When you use cutting fluids you help to remove chips. This ensures that the chip isn’t caught between the work piece and tool where it can cause scratches or a poor surface finish.
Reduction of bacterial growth
Bacteria affect cutting oils and it is essential to put in place measures that will reduce their growth. The growth of bacteria can turn your metal cutting fluid into a rancid one. While use of additives in coolants will reduce the bacteria’s effect, it is very important that you use pure water for coolant mixing.
Prevention of rust and corrosion
Cutting fluids protect the work piece, machines and tooling against corrosion and rust. These fluids usually leave a residual film long after the water evaporates. Prevention of corrosion increases the lifespan of your tools.
