What Should Pay Attention to When Using Metal Cutting Fluids?

Foaming Issues:

• Cutting fluids may produce foam during use, often related to dilution ratio, fluid temperature, and other factors.

• Solutions include increasing fluid temperature, adding foam inhibitors, and adjusting dilution properly.

Odor Problems:

• Cutting fluids may emit unpleasant or foul odors during use, which can be harmful to humans.

• The solution is to use high-quality raw materials to minimize odor and harmful substance generation.

Workpiece Rusting:

• Corrosion may occur due to the decomposition of extreme pressure (EP) additives in the cutting fluid, inadequate workpiece cleaning, improper handling, or poor storage conditions.

• Solutions include switching to environmentally friendly cutting fluids, cleaning workpiece surfaces promptly, and ensuring proper storage conditions.

Reduced Machining Accuracy:

• Insufficient or uneven cooling can lead to poor machining precision.

• Solutions include adjusting coolant nozzles, increasing supply pressure and flow rate.

• If the cutting fluid is unsuitable or degraded, replacement may be necessary.

Machine Tool or Workpiece Rusting:

• Rust may occur due to decreased cutting fluid concentration or a drop in pH.

• Solutions include regularly monitoring concentration changes and supplementing with alkaline additives to maintain proper pH levels.

• If the cutting fluid deteriorates, adding bactericides or replacing the fluid may be required.
