Oil mist from oli holes of the tool lubricates the cutting edge and remove chips. Oil mist from the collet holes lubricates the side edge and prolongs the tool life. Semi-dry machining, also known as MQL (Minimum Quantity Lubrication), is a machining method in which a small amount of cutting lubricant is nebulized with compressed air. Prevent environmental pollution by minimized use of cutting oil. Minimum quantity lubrication helps to restrain contamination such as oil leak in the plant. What's semi-dry machining?
