GRINDING BEARING RINGS & ROLLER HEADSQUAKERCOOL® 3532 BFF

THE SOLUTIONCHALLENGESA leading global manufacturer of industrial and automotive ball and roller bearings to OEMs was encountering a number of difficulties grinding bearing rings and roller heads. The customer was looking to replace the competitive coolants for both grinding operations due to residue inside the machine and on machined rings, and corrosion on roller heads after a year old fresh system fill. The customer was specifically look-ing for Quaker to: » Improve overall cleanliness

machining rings

» Eliminate corrosion on roller heads

» Move to a modern boron-free, biocide-free technology

Quaker was first brought in to analyze the ring cleanliness issue while grinding the internal diameter and face of steel rings. Quaker worked with the customer to understand the problem and developed QUAKERCOOL® 3532 BFF, a new, semi-synthetic coolant to replace the competitive fluid. This boron, formaldehyde and biocide free coolant was chosen as a solution because of its effective fines handling and good detergency characteristics providing excellent cleanliness on tools and machines. The customer was pleased with the cleanliness, ring surface quality, and also observed the anti-corrosion properties of the coolant and agreed to evaluate the same fluid in their roller head grinding operation to solve their corrosion issues. Grinding and finishing of the head rollers was done in a two-step process on the same machine and grinding wheel. Over the course of the second trial, the customer evaluated surface quality, found no corrosion on parts, and was satisfied with the results. QUAKERCOOL® 3532 BFF outperformed the competition in both trials and by utilizing this product in both bearing ring and roller head grinding applications, the customer realized the following:

» Improved cleanliness with elimination of residue on machined rings and inside the machine

» 25% Lower top ups and a decrease in working concentration grinding rings

» Lower amount of grinding burn on roller heads

» Improved corrosion protection

» Good operator acceptance with no smell and no skin irritation

» No foam issues and good biostability

GRINDING BEARING RINGS & ROLLER HEADSQUAKERCOOL® 3532 BFF

THE PRODUCT QUAKERCOOL® 3532 BFF is a low oil containing, machining and grinding fluid suitable for machining operations on most engineering materials. This technology combines the cleanliness and detergency of a synthetic product with the unique properties of oil containing emulsions and is recommended for general machining and grinding operations on steel and cast iron.

THE EXPERTISE

Metalworking lubricants represent a very minor part of the costs in a metalworking process, typically less than 1%. This case illustrates the importance of correct fluid selection. The impact of the fluid can be a multiple of its costs, making the price of a metalworking fluid insignificant. That is why Quaker focuses on developing fluids with the highest performance without compromise, fluids that sharpen your competitive edge.
