A cutting fluid’s main tasks
Cutting fluid is used to cool, lubricate and remove metal particles, swarf and dirt from the machine, which can otherwise increase wear on the machine and tools.
Desirable characteristics
Technical primary characteristics: A cutting fluid has to cool and lubricate effectively in the metalworking process. It also has to keep machines and tools clean and free of mess.
- Effective cooling and lubrication
- Good cleaning of machines and tools
- Effective removal of swarf
- Good cleaning of the grinding disc
Technical secondary characteristics: There are also secondary considerations with regard to technical properties. Here are some examples:
- Good corrosion/rust protection
- Low foaming tendency
- Low tendency to emulsify in leaked oil
- Must not damage machines or components
- Simple preparation
- Simple control methods
- Biostability
An optimal cutting fluid increases productivity and contributes to:
- higher cutting speeds
- fewer rejects
- longer tool life
- excellent surface finish
- better dimensional accuracy
- controlled swarf management
- lower energy consumption
Choosing a cutting fluid can be complicated, especially if you have several different processes and types of material to machine. If you need any help or advice, please contact us.
