content = """
Cutting fluids (coolants) serve critical functions in machining: heat dissipation,
chip evacuation, lubrication to reduce friction, and corrosion protection.
Proper fluid selection and management directly impact tool life and part quality.

**Types of Cutting Fluids:**
- **Soluble Oils (Emulsions):** Oil droplets suspended in water (1-10% concentration).
Good cooling and lubrication balance. Most common general-purpose coolant.
Require monitoring for bacterial growth and rancidity.
- **Semi-Synthetics:** Combine synthetic lubricants with small amounts of oil.
Clear appearance, good bio-stability, excellent heat transfer. Popular for CNC
machining centers.
- **Synthetics:** Water-based solutions with no petroleum oil. Superior cooling,
transparent for visibility, low foam. Best for grinding and high-heat operations.
Lubrication may be insufficient for heavy-duty cutting.
- **Straight Oils (Neat Oils):** Undiluted petroleum or vegetable oils. Maximum
lubrication for difficult materials (titanium, Inconel, tough stainless). Used
in mist form or flood application for heavy-forming operations.

**Delivery Methods:**
- **Flood Coolant:** High-volume flow (5-20 gallons/minute) through tool or
external nozzles. Effective for heat removal and chip flushing in milling.
- **Through-Spindle Coolant (TSC):** Pressurized coolant (300-1000+ PSI) delivered
through internal tool channels to the cutting edge. Essential for deep-hole
drilling, high-feed milling, and chip breaking in blind holes.
- **MQL (Minimum Quantity Lubrication):** Micro-doses of lubricant (aerosolized)
applied directly to the cut. Reduces fluid consumption and cleanup; ideal for
near-dry machining and environmentally sensitive applications.
- **Air Blast:** Compressed air clears chips without lubrication. Used for
temperature-sensitive materials or when coolant contamination must be avoided.

**Coolant Management:**
Maintain proper concentration (refractometer checks), pH balance (8.5-9.5
typical), and cleanliness (tramp oil removal, filtration). Skimmers, coalescers,
and centrifuges remove contamination. Regular system cleaning prevents bacterial
growth that causes odors and skin irritation.

**Health and Safety:**
Provide adequate ventilation and mist collection. Use PPE (gloves, safety glasses)
when handling concentrates. Follow disposal regulations for spent coolant,
typically as hazardous waste depending on contamination levels.
