How many types of coolant delivery are there?

Now that you already have coolant, you can use it in different ways. Using the wrong pressure may damage the tool.

1. Compressed Air

Air coolant removes chips and cools CNC milling tools. As one of the most cost-effective cooling methods, it is the preferred choice for sensitive materials. However, the disadvantage of this method is that it has no lubricating effect and is therefore not suitable for machining with high friction.

2. Flood cooling

In CNC aluminum projects, this method can be used to relieve heat. It involves spraying coolant between the tool and the milled aluminum. As a low-pressure method, it is also great for lubricating and removing chips from milling tools.

Using this liquid CNC coolant means spending a lot of time cleaning up the liquid around the machine at the end of the milling process.

3. Minimum Quantity Lubrication (MQL)

This process focuses on efficiency as opposed to the flooding method, which uses large amounts of CNC coolant. With MQL technology, machine operators and technicians can use the least amount of coolant on the machine. The amount used is based on the specific needs of the milling process.

This coolant is used in the form of an aerosol or fine mist, which reduces costs and environmental damage by accurately calculating the amount needed. However, errors can have a significant impact on machine operation.

4. Solid applications

To prevent water and soil contamination, machine operators can use solid lubricants such as industrial grease. However, regular application may require more effort while saving costs and protecting the environment. In addition, this is not an effective tool chip removal technique.
