CARE & HANDLING OF CUTTING FLUIDS

COOL

• Employ regular checks and proper maintenance of machinery.

• Use care when lubricating or filling up hydraulic systems.

• Use of oil wheel and belt skimmers is advisable.

)ebris and Di

• In machine tools, basic industrial sieves and traps are usually sufficient, larger swarf separate: out by gravity.

• Special systems may be required for cleaning grinding debris, dirt, and suspended materials from high finish applications.

• It is crucial to fully comply with federal, state and local regulations.

• Methods used to treat waste fluids depend on the type of product.

• In water dilutable coolants, the water (90-95% of volume) can be removed and the remaining solids disposed of.

• Wastewater treatment is divided into three tiers: Primary, Secondary, and Tertiary stages

- Primary: removing free oil (skimming) and suspended solids (filtration and settling)

- Secondary: ultrafiltration (cross-flow to remove oil and solids), chemical

treatment (most common way to split fluids - aluminum sulfate)

- Tertiary (carbon filtration and reverse osmosis)



	• Proper fluid flow is 2.5 - 3.0 gal.	- Accurate delivery to the cutting zone
	per min. per H.P.	- Machining speed
	• Trouble spots to check include:	- Condition of the cutting tool
	- State of the cutting fluid	- Sump size
	- Flow rate

• Turbulence

• Over-vigorous pumps

• Restrictions in the feed intake or coolant returns

• Mixing incompatible fluids

• Cleaner contamination

• Incorrect mixing or invert mixing

• Rich concentrations

• Sump too small

• Store cutting fluids indoors in sealed containers.

• Oil concentrate is added to water. (OIL = Oil In Last)

• Bacteria causes problems, instability in emulsions.

• Tramp oil causes emulsion overload, and promotes growth of bacteria.

• Used cutting fluids must be disposed of correctly.

• A heavy flow of fluid gives maximum value.
