Has MQL proven to extend tool life as well as the top rated water soluble flood coolants, in turning operations with carbide inserts on steel?

Yes, MQL can work well in turning applications.  However there are some special considerations that need to be addressed.  Since the cuttingedge of the tool is continuously in the cut, nozzle position is critical and more difficult.  Carbide tools can work well, but it is largely determined by the relative size of the parts and the length of […]

I am getting a mist and it is bothering my employees. What do I do?

Machining with minimum quantity lubrication has been shown to produce fewer emissions than flood cooling. It is, in fact, a low-emission process. Unfortunately, when starting with MQL, many shops think that more is better so they blast as far too much air through the MQLnozzles and literally create a fog or mist of lubricant in the air. This is not MQL! A […]

Is MQL the same as traditional flood coolant?

Minimum Quantity Lubrication (MQL) is not the same as traditional flood coolant.  In fact, it is very different.  Many people new to MQL are used to a flood coolant mindset and have trouble making the distinctions: MQL does not use a coolant. Traditional flood coolant uses a circulated liquid designed for heat transmission to carry heat away from the interface of the cutting tool and the work piece.
