DH EDM Dielectric Electric Sparks Machining Fluid Coolant Oil


SPECIAL PROPERTIES AND APPLICATION

DH is one of the “8.5”national key scientific & technology breakthrough project Won the Third grade prize of science & technology advancement from the Ministry of Machinery, and it is deeply refined & produced by adopting mine oil and cutting off narrow contents. It has many properties, such as low viscosity, high flash point, good anti-oxidation performance, excellent cooling and driving away metal chips performance, and non-irritation & non-toxicity. Comparing to common kerosene used in the electric sparks machining, DH has following advantages:

 1.High flash point, safety and low fire risks and low consumption and evaporation.

  2. Low aromatic content, non-toxicity and non-irritation. Improving working condition and      especial suitable for using on NC electric sparks machine with air condition environment.

  3. Highly improving machining speed, and reducing consumption of electric pole.
