Straight Grinding Oil | Straight Oil Based Lubricants

Stay Productive Throughout Grinding

High value machines, tools and parts intersect at a single point – a thin film of lubricant. The Benz commitment to Tribology, the science of interacting surfaces in motion, has guided over one hundred years of innovative grinding oil based lubricant development.

Our extensive line of oil based grinding lubricants are designed to maintain that essential film strength through an optimized combination of viscosity, hydrodynamic lubrication and extreme pressure film technology. Scores of Benz fluids utilizing hundreds of materials keep thousands of grinding applications productive while improving the overall quality and life of the equipment.

Globally recognized high performance grinding technology optimized for grinding productivity.

Innovation Backed by Research

Benz has engaged with research agencies and institutions, including the University of Wisconsin, the Defense Logistics Agency and Marquette University, in pioneering research that has expanded the understanding of grinding oil dynamics at the molecular level.

Our researchers have played a key role in establishing the mechanisms of extreme pressure film formation and the vital role polar oil based lubrications and fluid viscosity plays in grinding. We continue to participate and sponsor research to optimize fluid performance and sump life. Our team has utilized these findings in developing our straight grinding oil products.
