It is possible to use the term computer numerical control (CNC) machining to refer to any computer-automated tool control, such as spark cutting, water jet cutting, or plasma cutting. It is the purpose of this article to summarize the most significant advancements in overheating mitigation for CNC milling.

Cooling by flooding
Flood cooling, also known as wet cooling, is one of the most commonly used cooling techniques. One disadvantage is the high cost of cooling fluid, as well as the way it spreads inside and outside the machine, necessitating more cleanup. Furthermore, synthetic cooling fluid is frequently toxic and can generate particles that are hazardous to the environment and human health.

Solid lubrication is used in a variety of applications.
Strong metalworking liquids, such as industrial ointments, can be used to replace less viscous liquids in a variety of applications. It is also more cost-effective than flood cooling in many cases. Unfortunately, lubricant delivery is less efficient and less frictionless than a constant spray system, necessitating the application of lubricant to the contact area on a regular basis. Furthermore, solid lubrication is not recommended for applications that require the removal of material chips in a short period of time.

Minimum quantity lubrication (MQL) is a machining technique that aims to use the smallest amount of cutting liquid possible during the machining process.
As a result of the high volume of coolant required for flood cooling, which increases both the cost and environmental impact of the machining process, MQL seeks to reduce these factors by tailoring the coolant requirements to the specific requirements of a process. As a result, MQL processes must be designed with greater precision, because a calculation error could have catastrophic consequences for the machine or its operators.

Compressed air is used in many applications.
It is possible to completely eliminate the need for lubricant, alleviating the problems associated with disposal and variable costs. Using compressed air to cool and clear chips from a CNC machining process may very well be the most cost-effective and time-efficient method of doing so. Unfortunately, because compressed air cooling lacks lubricating properties, it is inapplicable to processes that involve a great deal of friction and heat transfer.

The use of cryogenic cooling
To keep the milling surface cool while cnc milling part is being used, liquid nitrogen can be injected into the tool during the process. Evidence has shown that this method produces a more even finished surface than flood cooling, and that the injected tools have a longer life cycle than their more conventional counterparts, both of which are beneficial. In light of the fact that it has relatively low variable costs due to the fact that Precision CNC Machining does not require a large quantity of flood coolant, it is a viable option for applications in which the application of exterior coolants is not practical.

Which method is the most effective?
According to the specific context in which Swiss CNC Machining is required, each method has advantages and disadvantages that can add value to a process depending on the specifics of the situation. It is critical to remember that selecting the most appropriate method for preventing overheating must be done first and foremost with the safety of the operators in mind. Many jurisdictions have regulations for machining processes, which undoubtedly has an impact on the decision on which cooling method to use.
