Preface
Cooling is essential in the CNC machining process. Coolant is used for a variety of purposes to ensure that the machine operates efficiently and accurately. Using the right type of CNC machining coolant during milling, grinding, or turning can prevent overheating and extend tool life.
Milling technology is one of the most commonly used CNC processes in the industry. It is ideal for producing custom-designed parts on a range of materials. However, companies that specialize in CNC machining aluminum alloy parts must use coolant to limit and control milling cutter overheating.
What is the importance of CNC machining coolant?
The effect of aluminum alloy CNC machining coolant In the cutting process, high temperature is very harmful to the workpiece, chips and tools. Heat energy can permanently damage the cutter or cause physical injury to the technician. That's why CNC coolant is essential in the machining process.
1. Lubrication
Coolant and lubricant are sometimes used interchangeably. However, they are not the same. Coolant is used during the milling process to reduce friction between the tool and the removal of chips. Aluminum as a material can be very sticky and will tend to knives. Coolant can make things slippery and make chips stick to it.
2. For cooling
Heat build-up is dangerous for both tool and machine operators. CNC machining coolant can be used to reduce the temperature of the workpiece and tool. Heavy cutting operations take a long time and generate heat faster.
3. Reduce corrosion
CNC machining coolant is essential for protecting tools and fabrication parts from corrosion. By providing the necessary lubrication, the machining process is seamless with minimal surface damage.
What types of coolants can be used for CNC machining aluminum alloys?
The choice of CNC machining coolant is based solely on the properties of the product and the materials used. Some types of coolants work better than others and also have different uses. You should choose your coolant based on whether you just need cooling, as a lubricant, chip removal, or all the functions. There are different types of coolants, including liquids, gels, and aerosols. Liquid coolants are the most common and come in soluble oils, pure oils, synthetic and semi-synthetic fluids.
In CNC aluminum projects, you need a coolant with a high oil content, such as pure oil. This is the best option because aluminum tends to be very sticky; Therefore, you need a lot of lubrication to keep the chips away from the milling cutter. Straight oils have a base mineral oil or petroleum composition that works in an undiluted form. Lubricants such as vegetable oils, esters, and fats are essential in the CNC milling process.
What to consider when using CNC machining coolant?
During the use of CNC coolant, the concentration level needs to be carefully considered. Deficits or surpluses can affect machines and increase manufacturing and repair costs.
1. Low coolant concentration
If the quantity is small, the manufacturer will incur costs due to overheating and friction. In addition, milling cutters can reduce life and cause corrosion of workpieces and machines. In addition, the tool may harbor bacteria, which can reduce its performance level.
2. High coolant concentration
On the other hand, if a technician uses too much CNC coolant during the milling process, there will be a lot of concentrate waste. Excess can form residues on the machining tool, which can shorten the working life. In addition, this large amount of coolant can contaminate the workpiece and tool. For operators, they can cause skin irritation due to chemicals.
Summary:
CNC coolant is a necessity in the aluminum machining process. Choosing the right coolant and application method ensures that the tool and the aluminium parts are lubricated and prevent overheating during the milling process. During application, the coolant concentration is checked to prevent further damage to the machine. These coolants can extend the life of your machines and make your company more cost-effective.
