MQL" is an abbreviation for Minimum Quantity Lubrication, which means "minimum quantity lubrication" in Japanese. This is a new machining method that performs cutting by continuously supplying a small amount of lubricating fluid, mainly made of highly biodegradable and environmentally friendly vegetable oil or ester oil, to the tip of the tool at a pinpoint point. It is sometimes expressed as semi-dry processing, near-dry processing, or MMKS.
With "MQL", it is now possible to reduce the amount of cutting fluid (coolant) used as close to "zero" as possible. Hocos was one of the first to engage in research and development and established its own method, iMQL® (spindle internal mixing).
iMQL® (spindle internal mixing) is a method in which air is mixed with a small amount of cutting fluid supplied separately in the spindle just before the tool shank, and the mixture is injected from the tip of the cutting tool. This method allows for frequent ATC, high-speed spindle rotation, and high-speed feed without time lag.
■Main features
・Improving the factory environment and reducing environmental impact.
・Achieved approximately 60% cost reduction compared to medium pressure coolant through.
・Achieves high efficiency machining in conventional neck processes. High efficiency can be achieved with a machine that combines high speed and high rigidity.
- Machining accuracy for the 1,800th hole.
・Achieved drilling over 10,000 holes.
