CNC machines allow manufacturers to produce highly uniform parts very quickly with tools controlled by a central computer. As with any machining tools, these devices produce a great deal of heat, which can distort or destroy the parts during production. Professional machining technicians will be familiar with the types of coolants available and know which delivery methods to use to increase your profitability and reduce waste. Take a look at more information on this critical aspect of machining below. 

A Guide to Coolants in CNC Machines

Lubricants Vs. Coolants

Lubricants and coolants have some overlapping functions, but they aren’t interchangeable. For instance, some coolants don’t lubricate the surfaces being worked, making them ideal for reactive materials that can be damaged by commercial lubricants. Compressed air, for example, cools surfaces and clears away chips without interacting directly with the surface of the part.

Coolant Delivery Methods

Mist coolants, for instance, disperse a fine mist oil over the surface as the tool is working, reducing friction and heat. For highly detailed projects or materials that produce higher amounts of debris, a flood technique is often a better choice. This technique completely submerges the part in coolant, instantly reducing heat and washing away chips before they can damage the tool.

Minimum Quantity Lubricant Technology

Many CNC machines will effectively calculate the minimum amount of coolant required for a project, which is usually applied as a mist or fine aerosol spray. Having the machine monitor coolant application can dramatically improve a machine shop’s efficiency and avoid wasting valuable materials.
