  • Enhances surface finish quality and machining accuracy

  • Excellent tackiness for strong slideway adhesion

  • Effectively separates from water-miscible cutting fluids

  • Anti-wear properties extend component life in combined systems

  • Protects against corrosion, even in wet environments

  • Suitable for both horizontal and vertical slideway lubrication

  • Former name: Shell Tonna S

Global Product Code: 001D7774



Application:

Shell Tonna S3 M 68 is a high-performance slideway lubricant developed for use in machine tool slideways, tables, and feed mechanisms—particularly in high-precision and slow-moving machinery. It is also suitable for combined systems involving hydraulics, gearboxes, and headstocks. Formerly marketed as Shell Tonna S.

Performance Features & Benefits:

  • Excellent Stick-Slip Control: Reduces frictional instability in slow-speed machine slideways, improving dimensional accuracy and surface finish.
  • OEM-Developed: Engineered in collaboration with advanced machine tool manufacturers for compatibility with diverse materials.
  • High Adhesion: Resists wash-off by cutting fluids, providing longer-lasting lubrication and stable performance.
  • Coolant Compatibility: Quickly separates from water-miscible metalworking fluids, allowing clean skimming and maintenance.
  • Multi-System Protection: Delivers anti-wear benefits to slideways, gears, bearings, and hydraulic systems.
  • Corrosion Resistance: Shields components exposed to cutting fluids and moisture.

Main Application Areas:

  • Machine tool slideways, tables, and feed mechanisms
  • Hydraulic systems in machine tools with shared lubrication
  • Gearboxes, headstock spindles, and vertical slides
  • Suitable for slideway surfaces made of cast iron and synthetic materials
