Metalworking ranges from tempering to metal forming to metal removing fluids. The TOTAL range includes oil-based and water-based lubricants.
Cutting and grinding are the most commonly encountered metal removing fluid operations. The machining fluids are diverse due to the wide range of possible machining operations and metals that are encountered. Common metals include ferrous (iron), aluminum, yellow metals and aerospace alloys. The cutting and grinding fluids are divided into oilbased (Scilia and Valona) and water-based (Lactuca, Spirit and Vulsol) families.
Metal forming operations range from stamping to drawing/ironing and forging. The metallurgy and the difficulty of the operation vary. Martol is the family for forming oils while Lubrilam is our rolling oil family.
Tempering of metals often uses quenching oils. Quenching operations depend upon the metal and the size and geometry of the part. Drasta is the family of quenching oils.
- Always add fresh concentrate to water
- Never add water into concentrate
- Always use an accurate proportioner
Length" x Height" x Width" X 7.48 1728 (cu-in / cu-ft)
Chlorine: activates between 100˚C & 130˚C
Phosphorus: activates between 210˚C & 250˚C
Sulfur: activates between 510˚C & 600˚C
- Be certain the refractometer sight glass is clean
- Zero out the refractometer with the water used to mix the coolant
- Add a few drops of water to the glass and fold the flap down
- Read through the sight hole and adjust to zero
- Reading will be where the blue and white areas meet
- Add coolant from the sump to the clean glass
- Reading occurs where the blue and white areas meet
- If the line is very blurred, you may have picked up a sample with tramp oil
- Clean glass again
- Take a clean sample from a tramp oil free area of the sump and re-read
- Use this value as the reading
- Take the reading from the refractometer and multiply it by the RI multiplier above to determine concentration
- To ensure accuracy calibrate the refractometer before use
- Soluble oils read at a 1-1 ratio. 1% = 1 on the refractometer
- We recommend the Atago 1-32 refractometer for most coolants
- Check concentration daily
- Check pH weekly
- Check pH every 2-3 days for soluble oils
