Water based Synthetic Grinding Coolant SW-5000

If your roll grinding workshop is troubled by persistent foam overflow, floating tramp oil mixing into coolant, hard-to-filter metal swarf and frequent rust on finished rolls, ROLITOM SW-5000 water-based synthetic grinding coolant delivers a stable, low-maintenance machining solution tailor-made for ferrous metal roll grinding processes.

Unlike ordinary synthetic grinding fluids blended with mineral oil, sulfur, chlorine or phosphorus additives, SW-5000 adopts a fully clean, hazard-free formula. The concentrated stock liquid is light-colored with faint odor; once diluted with deionized water, the solution turns completely transparent, letting operators observe wheel contact, swarf sediment and oil contamination at a glance during continuous roll grinding production.

Its most unmatched competitive edge is naturally ultra-low foaming performance—we never add extra anti-foam agents in the formula. This avoids secondary pollution caused by defoamer degradation, keeps smooth fluid circulation under slow feed abrasive machining and shaving grinding, and greatly cuts down daily tank cleaning work for roll manufacturers.

Key Advantages of SW-5000 Roll Grinding Synthetic Coolant

• Powerful cooling performance for roll grindingFast heat transfer absorbs high temperature generated at the grinding contact zone instantly, prevents thermal deformation of steel rolls, stabilizes dimensional precision and reduces abrasive wheel wear frequency in long-hour batch roll processing.

• Rapid swarf settling for cast iron & carbon steel grindingFine metal debris from roll grinding sinks rapidly to the bottom of circulation tanks instead of suspending in liquid, reduces filter clogging, lowers filter replacement cost and keeps machine work surfaces clean.

• Full anti-corrosion protection for all ferrous workpiecesForms a uniform protective film on carbon steel, nodular iron and cast iron surfaces, providing reliable inter-process anti-rust storage for semi-finished and finished rolls as well as machine internal metal parts.

• Natural low foaming, no extra defoamer requiredNo artificial foam suppressors added in the formulation. Even under continuous high-flow circulation for roll shaving grinding, foam volume stays minimal to prevent liquid overflow and sensor misreading.

• Excellent tramp oil separation & rejectionGearbox leakage oil floats separately on the coolant surface without emulsification, easy to skim off manually. This core feature extends fluid service cycle by nearly 40% compared with general grinding coolants for roll processing.

• Stable bio-stability for long-term productionBalanced pH value inhibits bacteria and mold reproduction inside coolant tanks, reduces unpleasant odor and frequent fluid replacement for 24h non-stop roll grinding workshops.

• Eco-friendly zero-hazard formula100% mineral oil-free, without sulfur, chlorine and phosphorus additives; low-concentration odor reduces workshop air irritation and meets mainstream industrial wastewater discharge standards for overseas metal processing factories.

Typical Physical & Chemical Properties

Application Range

Suitable Workpiece Materials

Cast iron, nodular iron, plain carbon steel (all ferrous roll blanks and structural steel parts)

Matching Grinding Operations

Slow feed abrasive machining, roll shaving grinding, general cylindrical grinding, light & medium load precision roll grinding

Target End Users

Steel roll manufacturing plants, metal foundries, precision grinding job shops, general machinery processing factories

Standard Operation Instructions

1. Full system cleaning before initial useThoroughly wash grinding machine circulation tank, pipelines and filters to remove residual old coolant, sludge and floating tramp oil, preventing interference to SW-5000’s grinding performance.

2. Adjustable dilution ratioMix concentrate with clean water at 1:15 ~ 1:40 ratio; adopt higher concentration for heavy-load roll grinding tasks, lower ratio for light precision grinding.

3. Recommended dilution mediumDeionized water is the optimal choice to maximize anti-rust property and fluid service life; clean soft tap water can be used temporarily for small-batch roll production.
