Which CNC coolant should be selected for aluminum alloy cnc machining?
Cooling is essential in CNC machining. The coolant has many uses to ensure the efficient and accurate operation of the machine. Using the correct type of CNC coolant during milling, grinding, or turning can prevent overheating and extend tool life.
Milling technology is one of the most commonly used NC processes in the industry. It is very suitable for producing custom designed parts on a range of materials. However, companies specializing in machining CNC aluminum alloy parts must use coolant to limit and control the overheating of milling cutters.

Cnc machining of aluminum alloy
What is the importance of CNC processing coolant and what should you choose? Let's discuss it.
Effect of Coolant on Aluminum Alloy CNC Machining
In the cutting process, high temperature is very harmful to the workpiece, chips and tools. Thermal energy may permanently damage the milling cutter or cause physical injury to technicians. This is why CNC coolant is indispensable during machining.

·Lubrication
Coolants and lubricants can sometimes be used interchangeably. However, they are not the same. Coolant is used during milling to reduce friction between the tool and chip removal.
Aluminum, as a material, can be very sticky and tends to the tool. The coolant makes things slippery and makes chips stick to them.

·For cooling
The accumulation of heat is dangerous for both the tool and the machine operator. CNC machining coolant can be used to reduce the temperature of the workpiece and tool. The heavy cutting operation takes a long time and generates heat faster.
·Reduce corrosion
CNC coolant is essential to protect tools and manufactured parts from corrosion. By providing the necessary lubrication, the machining process is seamless with minimal surface damage.
Type of coolant used by Cnc when machining aluminum alloy
The choice of CNC coolant is entirely based on the performance of the product and the materials used. Some types of coolants are better than others and have different uses. You should choose the coolant depending on whether you only need cooling, as a lubricant, chip removal, or all functions.

There are different types of coolants, including liquids, gel and aerosols. Liquid coolants are the most common, including soluble oils, pure oils, synthetic and semi synthetic fluids.
In the CNC aluminum project, you need a coolant with high oil content, such as pure oil. This is the best choice, because aluminum is often very sticky; Therefore, you need a lot of lubrication to prevent chips from moving away from the milling cutter. Straight oil has a base mineral oil or petroleum composition that functions in an undiluted form. Lubricants (such as vegetable oils, esters and fats) are essential in CNC milling.

Aluminum alloy processing
What to consider when using CNC coolant
The concentration level needs to be carefully considered when using CNC coolant. Deficits or surpluses affect machines and increase manufacturing and maintenance costs.

·Low coolant concentration
If the quantity is small, the manufacturer will incur costs due to overheating and friction. In addition, the milling cutter will reduce its life and cause corrosion of the workpiece and the machine. In addition, the tool may breed bacteria, thereby reducing its performance level.
·High coolant concentration
On the other hand, if technicians use too much CNC coolant in the milling process, there will be a lot of concentrate waste. Excess will form residues on the machining tools, thus reducing the working life.
In addition, such a large amount of coolant may contaminate the workpiece and tools. For operators, they may cause skin irritation due to chemicals.

generalization
CNC coolant is a necessity in aluminum processing. The proper selection of coolant and application method can ensure that the tools and aluminum customized parts are lubricated during the milling process and prevent overheating. During application, check the coolant concentration to prevent further damage to the machine.
