Shell Tonna S2 M68  oils are specially designed for the lubrication of machine tool slides, tables and feed mechanisms. Their enhanced tackiness and stick-slip characteristics combine to offer superior frictional performance on slideways. They are specially recommended in cases where high exposure to soluble cutting fluids exist. 

 • Ready separation from water-miscible cutting fluids Separates completely and immediately from water-misciblemetalworking fluids allowing easy removal by skimming. This helps to achieve longer coolant life, better cutting performance and to reduce Health & Safety issues.• Good slideway adhesionProvides very effective adhesion to slideway surfaces, resistingwash-off by metalworking fluids and thus reducing oil consumption and giving more uniform working condition for the machine.• Good frictional properties“Stick-slip” problems are overcome allowing more accuratepositioning. This provides benefits of improved finished surface quality and dimensional accuracy of work pieces.• Good anti-wear performanceProvides anti-wear protection for slideways, gears, bearingsand hydraulic system components.• Excellent corrosion prevention characteristicsProvides effective prevention of machine tool surfaces andcomponents in the presence of water-miscible cutting fluids

 • Machine tool slideways, tables and feed mechanisms Developed for use on a wide range of materials used formachine tool slideway surfaces, including cast iron and synthetic materials.Shell Tonna S2 M oils can be used also in the hydraulic and gearboxes system although in such applications Shell Tonna S3 M oils are generally preferable.The lower viscosity grades are intended for horizontal slide lubrication (Shell Tonna S2 M 32 or 68).  For vertical slides use Shell Tonna S2 M 220.Specifications, Approvals & Recommendations• Fives Cincinnati P-50 (ISO 220), P-47 (ISO 68), P-53 (ISO 32)• ISO 19378 / ISO 6743-13 GA and GB DIN CGLP• CGLP Slideway Oils against DIN 51502For a full listing of equipment approvals and recommendations, please consult your local Shell Technical Helpdesk.
