Product description:
Gaoke spark oil is manufactured by refined hydrotreated mineral oil through precision cutting. It can be divided into three models.
Performance features:
Low viscosity, good cooling property.
High flash point and boiling point.
Good insulating property
Low odor, the decomposed gas during processing is non-toxic, thus it is safe to operator.
No pollution to machined part, non-corrosive
Good oxidation security, long service life
Uses:
Suitable for various spark machine tools as working solution.
