MQL is a microlubrication technique that delivers a precise air-oil aerosol directly to the cutting edge — no tanks, no sumps, no wastewater. Cleaner machining, longer tool life, faster cycles, and a fraction of the operating cost.
MQL stands for Minimum Quantity Lubrication. Instead of flooding the cutting zone with hundreds of litres of water-based coolant, MQL produces a fine aerosol of compressed air and a few ounces of vegetable-based ester lubricant — and delivers it directly to the cutting edge.
The result is near-dry machining. Lubrication exactly where it's needed, in exactly the right amount. No flooding. No mess. No waste. The chip leaves the cutting zone dry, the tool stays at consistent temperature, and the workshop floor stays clean.
This isn't a cost-cutting compromise. MQL has been the European and Japanese standard for high-performance machining for decades — particularly for exotic alloys, high-speed cutting, and any operation where flood coolant is a liability as ESG guidelines need to be met across international supply chains.
ESG is international now. If your customers export, report sustainability metrics, or supply regulated sectors, coolant-heavy machining quickly becomes a question on audits, disclosures, and vendor approval.
Ogale MQL removes water usage, hazardous coolant disposal, and biocide handling from the process. That means cleaner environmental metrics, safer operator exposure, and a machining line that is easier to defend in procurement reviews and ESG reporting.
Eleven points of comparison that matter on the shop floor — operating cost, maintenance, environment, and worker safety.
Every advantage of MQL traces back to one principle: lubricate exactly where you need to, exactly as much as you need to. Here's how that translates into shop-floor outcomes.
The single biggest cause of premature tool failure isn't wear — it's thermal shock. Flood coolant rapidly cools the tool when it touches the workpiece, then lets it heat back up when the cut breaks. Repeat this cycle thousands of times and you get micro-fractures in the cutting edge.
MQL keeps the tool at a consistent temperature throughout the cut. No thermal cycling. No micro-fractures. Just longer tool life.
Once thermal limits are removed, you can run the cut harder. Higher feed rates, higher cutting speeds, higher RPM — without sacrificing surface finish or tool life. That's the operational advantage MQL unlocks.
Shops that switch from flood coolant to MQL routinely see 20–30% reductions in cycle time on the same machine, with the same operator, on the same parts.
A flood coolant system needs water, 7-15 litres of coolant oil charge per day, biocide, filtration media, sump cleaning, and waste disposal. The recurring cost is significant — and that's before you count maintenance time.
MQL needs compressed air and a small amount of oil. Ogale MQL typically uses 2-2.5 litres per day. No water. No biocide. No disposal cost.
The lubricant matters as much as the system. KwikKut® OMSecolube is more than 99.7% vegetable-based, food-grade (FSSAI), biodegradable, and non-toxic. HMIS health rating: 0. Flammability: 0. Physical hazard: 0. Not listed as a carcinogen.
For workers on the shop floor, this means clean air and no skin irritation. For your facility, it means no hazardous waste, no wastewater treatment, easier dry-chip disposal, and a cleaner path to ESG compliance.
MQL is suitable for almost every metal-cutting and forming process. Through-spindle delivery for internal lubrication. Open-cast nozzles for external. Both work on all major CNC brands.
Through-spindle and open-cast delivery. Increases cutting speed without thermal damage. Particularly effective for high-speed machining of aluminium and exotic alloys.
Through-spindle MQL delivers lubricant straight to the drill point, even in deep-hole applications. Eliminates chip evacuation problems associated with flood coolant.
Precise lubrication at the tap engagement zone — fewer broken taps, cleaner threads, better surface finish on internal threads.
Open-cast aerosol delivery for external turning. Dry, corrosion-free chips that fall away cleanly. No chip recutting.
Continuous lubrication throughout the broach pass. Better tool life on broaches and cleaner finish on internal splines and keyways.
Reduces friction at the die-workpiece interface. Cleaner formed parts, longer die life, no flood coolant cleanup.
