Lube Additives for Metal Removal Fluids (Cutting/Grinding)
Overview:
Severe boundary conditions at the tool–workpiece interface generate heat and adhesive wear; lubricity and EP chemistry are needed to prevent welding and extend tool life.
Why an additive package is required:
- Reduce friction and cutting forces to improve surface finish and dimensional control.
- Provide EP chemistry to prevent seizure/welding under high contact stresses.
- Control foam and corrosion (especially for ferrous and yellow metals) and maintain cleanliness with tramp oil/coolant systems.
Typical additive families employed:
Friction modifiers/ester lubricity agents, sulfurized/phosphorus EP chemistries (chlorinated chemistries are often restricted), corrosion inhibitors, defoamers, biocide packages for waterborne systems.
Indicative performance tests:
Falex pin & vee block (ASTM D3233), 4-ball EP (ASTM D2783), tapping torque, foam (ASTM D892), copper strip corrosion (ASTM D130), staining tests per OEM/customer methods.
