Machining is a complex line of work. Knowing the specifics of what system to choose and which coolant to use to maintain it is key to your ongoing success. What kind of coolant should you be using for HSS cutting tools? What about carbide cutting tools? The answer is here and it’s likely simpler than you think!
Tips to Remember
Before you get to the business of sorting out which type of coolant you will need for your machinery, it’s important to know some general tips for using coolant properly.
- Always maintain adequate levels of coolant in your machinery. This ensures pressure will be sufficient and protects your machinery from rust.
- Mixing different types of coolants together or using the wrong type of coolant in a machine with strict requirements can cause damage to both machine and part and is not advised.
Putting Coolants to Work
Match your coolant to the cutting action you are performing. While some actions can make do with either mist or flood coolants, high-intensity or high-friction actions will require flood coolant every time.
Flood coolants are also often referred to as lubricants, as they are typically used both for flushing out tiny shards or chips or metal after cutting and for keeping machines that are not prone to overheat moving smoothly. Carbide cutting tools are prone to overheat but are also temperature-sensitive. This means that using a flood coolant might shock the metal and cause splintering or fracturing. Mist coolants are the best choice for these cutters.
Materials Matter
Coolants may be created from pure oils or may be mixed with water. The water mixture is typically the case with full synthetics. Some machines call for one or the other, so be aware of which is required by your machinery. Oil-based coolants are slicker and are great for aluminum surfaces that can become sticky. Synthetics are better for steel.
A Lot to Remember!
This information may leave your head spinning if you’re still new to purchasing your own coolant. When in doubt, trust your machinery supply merchant for expert advice and guidance on the best coolants to buy for your company’s machines.
