Metalworking and Machining


Metal machining s involves high friction, high temperatures and high stresses, resulting in tool wear. A lubricant or a metalworking fluid is used to minimize these effects. Metalworking fluids accomplish this by providing cooling, lubrication and corrosion resistance. Over time, cutting fluids can become contaminated by chips and fines, tramp oil, bacteria and dissolved salts. Therefore, monitoring the pH, water hardness and fluid concentration is essential in preventing failure of the fluid.

Water evaporation should be monitored to ensure the coolant-to-water ratio is correctly maintained. Vaisala K-PATENTS® Process Refractometer provides accurate and continuous measurement of the coolant-to-water ratio.

The Process Refractometer applications can be divided into four areas:

  1. Quenching/Tempering Process
  2. Cooling/Cutting
  3. Washing
  4. Rinsing

Vaisala K-PATENTS® Sanitary Probe Refractometer PR-43-AP is ideal for installation in larger pipes or vessels. The Sanitary Compact Refractometer PR-43-AC with a flow-cell is suitable for smaller pipes.
