No Room to Cut Corners

Cutting fluid may be one of the smallest expenses in a finishing operation, but it's one of the most crucial. Weak cutting fluid can cause several imperfections that lead to rejected parts and lost productivity. Even slight decreases in cycle time or abrasive consumption over time will repay the cost of dedicated cutting fluid-several times over.

Proper cutting fluid prevents complications like:

  • Higher surface roughness on workpieces
  • Unnecessary welding of metal chips to workpieces
  • Ruined honing tools and abrasives
