Metalworking fluid (MWF) is used to:

Cool and Lubricate: Reduces heat and friction during machining processes.
Protect Tools and Workpieces: Minimizes wear and prevents corrosion.
Improve Surface Finish: Enhances the quality of the finished product.
Assist in Chip Removal: Helps in clearing debris from the cutting area.
MWFs are essential in operations like milling, turning, drilling, and grinding across various industries, including automotive, aerospace, and metal fabrication.
