Shell Tonna S3 M 32
Shell Tonna S3 M 32 is a premium machine tool slideway oil developed to provide reliable lubrication, precise friction control and strong protection for machine tool slideways, tables and feed mechanisms. Formulated using carefully selected base oils and advanced additive technology, Shell Tonna S3 M 32 delivers excellent stick-slip control and strong adhesion to slideway surfaces. The formulation is designed to support accurate machine movement and consistent lubrication in demanding machining environments where exposure to metalworking fluids is common.
One of the key advantages of Shell Tonna S3 M 32 is its excellent frictional performance. The lubricant is specifically designed to overcome stick-slip behaviour that can occur during slow or intermittent movement of machine slideways. By minimising stick-slip effects, Shell Tonna S3 M 32 allows smoother and more controlled slide movement. This improved motion control supports more accurate positioning of machine tool components, helping improve surface finish quality and dimensional accuracy of manufactured parts.
Shell Tonna S3 M 32 also provides strong adhesion to slideway surfaces. The formulation contains tackiness additives that help the oil remain attached to metal surfaces even when exposed to water-based cutting fluids. This strong adhesion helps resist wash-off from metalworking fluids and ensures consistent lubrication across the slideway surfaces. As a result, Shell Tonna S3 M 32 helps reduce oil consumption and maintain stable operating conditions for machine tools during production.
Another important benefit of Shell Tonna S3 M 32 is its excellent separation from water-miscible cutting fluids. The oil separates readily from soluble metalworking fluids, allowing contaminants to be easily removed through skimming. This separation capability helps maintain coolant cleanliness, extend coolant service life and support improved cutting performance while reducing potential health and safety concerns associated with contaminated coolant systems.
Shell Tonna S3 M 32 also provides excellent anti-wear and corrosion protection for machine tool components. The advanced additive system forms a durable lubricating film between metal surfaces, helping protect slideways, gears, bearings and hydraulic components from wear. In addition, the formulation provides effective corrosion protection for machine tool surfaces and components when exposed to moisture or water-miscible cutting fluids.
Shell Tonna S3 M 32 is particularly suited for horizontal machine tool slideways where lower viscosity oils are required for efficient lubrication and smooth operation. It is compatible with a wide range of slideway materials including cast iron and synthetic materials and can also be used in machine tool hydraulic systems, gearboxes and headstocks, particularly where combined lubrication systems are present.
Physical characteristics include a kinematic viscosity of approximately 32 mm²/s at 40°C and 5.4 mm²/s at 100°C with a viscosity index of approximately 100. Shell Tonna S3 M 32 has a density of approximately 870 kg/m³ at 15°C, a flash point of around 215°C and a pour point of approximately −30°C, supporting reliable lubrication performance in precision machine tool applications.
