Aerospace | Q-COOL 355D


Q-COOL 355D exceeded expectations by quadrupling the runtime per tap on titanium parts, eliminating scrap, reducing usage rates, and improving surface finishes.

The Challenge

This premier manufacturer of energetic components and complex integrated systems supports the defense, space, and commercial markets. Their state-of-the-art facility has over 110,000 square feet for engineering and analysis, prototype development, testing, qualification and production.

They were running a leading competitor’s clear, full synthetic product with deionized water (DI), and having tapping issues – oversized threads, poor thread quality, chip buildup, trouble holding tolerances, and tap breakage. All these issues resulted in bad parts and increased scrap rates. In addition to experiencing higher usage rates, they noticed heavy residues and deterioration of the paint and seals on the machines.

They contacted the local QualiChem distributor for help. The distributor recommended Q-COOL 355D, which increased tool life, improved surface finishes, reduced usage rates, and eliminated all scrap. The manufacturer was also able to save up to $500 per drum.

The Solution

Neutral pH Heavy Duty Synthetic

Q-COOL 355D is an oil-rejecting water clear coolant that provides excellent in-process corrosion protection for parts and machine tools. It has a neutral pH to prevent staining on sensitive aluminum and aerospace alloys. It runs clean, has excellent bioresistance, and is non-foaming. This product has state-of-the-art additive technology to improve tool life and part quality in severe machining operations.
