There are two types of cutting fluids used in CNC machining in Dongguan: one is oil-based cutting fluid and the other is water-based cutting fluid;

The cutting fluid used in cnc machining is divided into four types: cutting oil, emulsion, semi-synthetic fluid, and synthetic fluid; for the above four cnc machining cutting fluids,

You may commonly use cutting oil, emulsion (called soapy water in some places), synthetic fluid (many people call it environmentally friendly fluid), and you may know less about semi-synthetic nights;

How do you choose cutting fluid during machining? Let’s take a look at the advantages and disadvantages of each cutting fluid:

1. Cutting oil for CNC machining in Dongguan:

advantage:

  • a. Very high physical lubrication
  • b. Suitable for low speed, less cutting allowance
  • c. Provide very good surface finish
  • Disadvantages:
  • a. Poor heat transfer
  • b. Fire hazards
  • c. High usage cost
  • d. Smoke/fog

2. Emulsion used in Dongguan CNC machining:

advantage:

Better lubrication

  • a. Safe for multiple metals
  • b. It has better cooling compared with cutting oil
  • c. Better scouring ability of iron filings
  • d. Lower cost than cutting oil
  • e. Better anti-rust
  • f. Easy to treat sewage

Disadvantages:

  • a. Increase in dosage
  • b. Emulsify dirty oil
  • c. Poor odor control
  • d. Dirty equipment
  • e. Poor stability against hard water
  • f. Poor filtering
  • g. Poor mixing

3. Semi-synthetic fluid used in Dongguan CNC machining:

advantage;

  • a. Better cooling than emulsion
  • b. Better anti-rust
  • c. Use cleaner than emulsion
  • d. Better filterability
  • e. More suitable for hard water and dirty oil
  • f. More suitable for hard water and dirty oil
  • g. It has better antibacterial properties than emulsion

Disadvantages:

  • a. There is a tendency to foam in soft water
  • b. Oil repellency is worse than synthetic fluid
  • c. When used in high concentrations, there may be skin allergies
  • 4. Synthetic fluid used in Dongguan CNC machining:

advantage:

  • a. Very good cleanliness
  • b. Will not smell
  • c. High operator acceptance
  • d. Low consumption turnover rate (12-20 weeks)
  • e. Very good cooling
  • f. Repellent oil completely
  • g. Low foam
  • h. Long service life
  • i. Very good filtration/fast settling performance

Disadvantages:

  • a. Low physical lubrication
  • b. Difficulty in sewage treatment
  • c. Sticky residue, especially in hard water
  • d. Not compatible with emulsion
  • e. React with some polycarbonate
  • f. Paint that may damage the machine tool
