Specifications and Approvals
Tonna S meets the following specifications:
- ISO 11158 / ISO 6743-4 HM and HG
- ISO 12925-1 / ISO 6743-6 CKC
- ISO 19378 / ISO 6743-13 GA and GB DIN CGLP
- Cincinnati Machine P-50 (ISO 220), P-47 (ISO 68)
Applications
- Machine tool slideways, tables and feed mechanisms
Developed for use on a wide range of materials used for machine tool slideway surfaces, including cast iron and synthetic materials.
- Machine tool hydraulic systems
Particularly recommended for machines which have a combined hydraulic and slideway lubrication system.
- Machine tool gearboxes and spindles
Also suitable for gear and headstock lubrication.
The lower viscosity grades are intended for horizontal slide lubrication (Tonna S 32 or 68): For vertical slides use Tonna S 220.
