When using metalworking machines, it is common to use a coolant to lubricate and cool the cutting tools, as well as to remove the chips and swarf produced during machining. In some cases, it is also beneficial to use the SmartJet™ to disperse the chips more efficiently. However, when using the SmartJet™ to disperse chips, it is essential to choose the right coolant to avoid the formation of fog when the air pressure is merged with the coolant.

When it comes to choosing an oil coolant for metalworking machines that are using SmartJet™, there are several factors to consider. One of the most important considerations is whether to use synthetic or mineral oil. Another critical factor is the viscosity of the oil.

Synthetic oil is often preferred over mineral oil when using the SmartJet™ because it has better cooling properties and is less likely to oxidize or break down when exposed to high temperatures. This can be especially important when using the SmartJet™, as the chips can generate a significant amount of heat that must be dissipated quickly to avoid damage to the machine or the workpiece.

Another advantage of using synthetic oil with the SmartJet™ is that it is less likely to produce fog than mineral oil. This is because synthetic oil typically has a lower vapor pressure than mineral oil, which means that it is less likely to evaporate and form a mist or fog when exposed to air pressure.

However, synthetic oil can be more expensive than mineral oil, which can make it less cost-effective for some metalworking applications. If cost is a significant consideration, it may be more appropriate to use mineral oil, which can provide adequate lubrication and cooling properties at a lower cost.

When it comes to viscosity, a low viscosity oil is generally preferred when using the SmartJet™. This is because a low viscosity oil can flow more easily and effectively through the machine and can better remove the chips and swarf produced during machining. A low viscosity oil can also help to prevent the formation of fog when using the SmartJet because it is less likely to create droplets that can evaporate and form a mist or fog.

However, it is important to note that the ideal viscosity of the oil will depend on the specific application and the requirements of the machine. In some cases, a higher viscosity oil may be necessary to provide adequate lubrication and cooling properties or to meet other performance requirements.

In addition to the choice of coolant and viscosity, there are several other factors to consider when using SmartJet™ in metalworking machines. One of the most important considerations is the design of the machine and the coolant delivery system. The coolant delivery system must be designed to deliver the coolant evenly and effectively to the cutting area, while also minimizing the formation of mist or fog.

 

 

The specific gravity of the oil used as a coolant can also have an effect on the formation of fog when using the SmartJet™ in metalworking machines.

When the coolant is atomized and dispersed by air pressure, it can form a fine mist or fog that can create a hazy environment in the workspace. This can be a safety hazard for workers and can also cause problems with visibility and machine maintenance.

The specific gravity of the coolant can affect the size of the droplets in the coolant mist. A higher specific gravity coolant will tend to produce larger droplets, which are less likely to form a fog. However, larger droplets can also reduce the effectiveness of the coolant in lubricating and cooling the tool.

A lower specific gravity coolant will tend to produce smaller droplets, which are more likely to form a fog. However, smaller droplets can also provide more effective cooling and lubrication, especially in high-speed machining applications.

Another critical factor to consider is the operating conditions of the machine, including the cutting speed, the type of material being machined, the temperature and humidity of the environment. These factors can affect the performance of the coolant and the effectiveness of the SmartJet™.

The choice of coolant and viscosity when using the SmartJet™ in metalworking machines will depend on the specific application and the requirements of the machine. In general, synthetic oil is preferred over mineral oil because it has better cooling properties and is less likely to produce fog. A low viscosity oil is also generally preferred because it can flow more easily and effectively through the machine and can better remove the chips and swarf produced during machining.

However, it is important to consider all factors carefully when selecting a coolant for metalworking machines, including the cost, performance requirements, and operating conditions of the machine. By choosing the right coolant and viscosity and designing an effective coolant delivery system, metalworking machines can operate efficiently and accurately, while also ensuring the safety of the operator and the quality of the finished product.
