Product Description
Coomcool GDW MG 68 is a lubricant specially developed for machine tool guideways. The formulation contains selected oleophilic agents, extreme pressure additives and additives with special adhesion properties, which can prevent the crawling phenomenon caused by low-speed movement of the guideway. At the same time, this product can also effectively reduce the vibration of machine movement, good adhesion can prevent the lubricant from being extruded.
Advantages
- Outstanding demulsifying properties – helps prevent soluble oil emulsions on plastic slideway surfaces.
- Avoids downtime and expensive slideway repair or replacement.
- Exceptional resistance to stick slip – helps to ensure highly accurate and repeatable machining.
- High quality output is maintained.
- Protects metals against staining and corrosion.
- Oil-wetted surfaces remain in good condition.
- Highly filterable – filters in oil supply remain unblocked.
Applications
Coomcool GDW MG 68 is suitable for all horizontal and vertical guideways, its excellent anti-emulsification properties extend the service life of the coolant; good friction characteristics prevent creeping phenomenon, improve the surface finish of machined parts and reduce the rework rate.
