In the high-stakes world of CNC machining, every drop of coolant saved translates to direct improvements in both profitability and sustainability. Unist’s Minimum Quantity Lubrication (MQL) technology is rewriting the rules of metal cutting by slashing coolant costs by up to 90% while delivering superior machining performance. Let’s explore how this innovative system is transforming shop floors and balance sheets alike.
The Hidden Costs of Traditional Coolant Systems
For decades, flood coolant systems dominated machining operations, but their true costs often go unnoticed. Beyond the obvious expense of purchasing gallons of coolant, manufacturers face:
- Energy-intensive fluid circulation systems
- Costly wastewater treatment and disposal
- Increased tool wear from thermal shock
- Labour hours lost to cleaning and maintenance
Unist’s MQL technology addresses these pain points head-on by replacing wasteful flood systems with precision lubrication.
Breaking Down the 90% Savings
1. Fluid Consumption Revolution
Traditional flood systems consume significant amounts of coolant per hour, while MQL uses dramatically less. This substantial reduction in fluid usage forms the foundation of cost savings. For a midsize machine shop running three shifts, this translates to:
- Thousands of gallons saved annually per machine
- Significant yearly savings on coolant purchases
2. Ancillary Cost Reductions
The savings extend far beyond lubricant purchases:
- Energy: Eliminating coolant pumps reduces power consumption substantially.
- Waste Management: Reduced or eliminated disposal fees.
- Tooling: Longer tool life through reduced thermal stress.
