Lube Additives for Slideway/Way Oils
Overview:
Machine tool slideways require low stick–slip and predictable friction to preserve positioning accuracy under mixed lubrication with coolant contamination.
Why an additive package is required:
- Adjust friction to eliminate chatter and stick–slip at low speeds.
- Provide AW/EP film strength under boundary contact and stop–start motion.
- Resist emulsification with water-based coolants while protecting against rust and staining.
Typical additive families employed:
Friction modifiers (boundary-layer control), AW/EP, tackifiers for adhesion, corrosion inhibitors, demulsifiers and anti-foam tailored for coolant environments.
Indicative performance tests:
OEM slideway friction/stick–slip evaluations (e.g., Cincinnati Machine), demulsibility (ASTM D1401), rust (ASTM D665), foam (ASTM D892).
