Description
SHELL TONNA S3 M 68
Premium Slideway Lubricant (ISO VG 68) for Machine Tool Guides, Slides, Tables, Feed Mechanisms & Precision Machining Equipment
Product Description
Shell Tonna S3 M 68 is a premium mineral-based slideway lubricant specially formulated for the lubrication of machine tool slideways, guide rails, tables, and feed mechanisms. It is designed to provide excellent stick-slip control, friction reduction, adhesion, wear protection, and corrosion resistance in precision machining applications.
The formulation contains highly refined mineral oils with specialised additives that improve lubricant adhesion to vertical and horizontal slide surfaces and provide reliable performance where accurate movement and smooth positioning are critical.
Features and Benefits
Excellent Stick-Slip Control
Shell Tonna S3 M 68 provides:
- Reduced stick-slip movement
- Smooth slideway motion
- Improved machining accuracy
- Better surface finish quality
This is especially important for low-speed and high-precision machine tools.
Excellent Adhesion to Slideways
The special additive technology provides:
- Strong oil film adhesion
- Reduced lubricant drain-off
- Reliable lubrication on vertical and horizontal surfaces
- Improved protection during intermittent operation
Superior Wear Protection
Provides protection against:
- Slideway wear
- Metal-to-metal contact
- Surface damage
- Mechanical friction
helping extend machine tool service life.
Good Water and Coolant Resistance
Designed for machine tool environments where contact with water-based coolants may occur:
- Good resistance to wash-off
- Improved coolant separation
- Reduced contamination of lubricant systems
Excellent Corrosion Protection
Protects machine surfaces against:
- Rust formation
- Corrosion during operation
- Moisture-related damage
