Water soluble cutting oil

Metal working fluids
Improved machinability
- · Reduction of cutting resistance
- · Suppression of B.U.E
- · Improved dimensional accuracy
- · Enlargement of tool lifetime
- · Improved roughness of cut surface
Improved workability
- · Cooling efficiency
- · Chip dischargeability (filter, pipe clogging prevention)
- · Adds anti-rust properties on workpiece materials (Especially the iron series) or machine tools
- · Excellent rot resistance → Increase of oil lifetime and reduction of rot smell
- · Highly vesicular → Reduction of bubble problems in processes
- · Exclusion of harmful substances → Eco-friendly cutting oil maximum suppression of environment contamination
Advantage of metal working fluids of Dong Sung Oil

- · Excellent oil stability in soft/hard water
- · Excellent lubricity, very good surface roughness, tool lifetime enlargement
- · Excellent anti-corrosiveness and no toxicity to skin through careful selection of preservatives.
- · Low bubbles and easy to treat waste water
- · Low harm to human because of being eco-friendly through production by removing all the internationally environmentally regulated substances.
