The system focuses on gas-assisted processing to blow away chips, potentially improving visibility and cleanliness during machining. It emphasizes safety, reduced water-related cleanup, and potential time savings by increasing cutting speeds and reducing tool wear. The value proposition centers on process efficiency and chip management in demanding workflows.
Fusion Cool 2255 – Premium Synthetic Coolant
Fusion Cool 2255 is a premium synthetic coolant designed for bandsaw cutting, CNC lubrication, plasma table fluid, and other metalworking tasks. It aims to provide enhanced lubricity under tougher machining conditions, protecting cutting edges where tool pressure is high or materials are abrasive. The product supports general-purpose coolant use and positions itself as a cross-over or replacement option for Kool Mist 77, offering strong lubrication and reliable performance across a range of operations.
Premium Synthetic Machining Coolant (1 Gallon)
This premium synthetic machining coolant is designed to extend coolant cycles, protect tooling and sumps, and reject tramp oil. The formulation emphasizes clean machine environments, improved tool life, and stable performance across a variety of machining operations. It is positioned for users seeking high-quality synthetic chemistry to sustain demanding workloads with consistent results.
Premium Soluble Machining Fluid – 1 Gallon
Premium Soluble Machining Fluid is a non-chlorinated coolant featuring excellent solubility in both soft and hard water. Its light viscosity base oils help maintain a cleaner machine environment, reducing buildup and maintenance. This solvent-friendly formula aims to provide reliable lubrication and cooling while avoiding chlorinated compounds, aligning with safer, more environmentally conscious machining practices.
Buying Guide: Key Purchase Considerations
- Mix ratio and concentration: Many mist coolants require dilution with water. Verify recommended ratios (for example, 5-10% coolant to 90-95% water) to balance lubrication, heat transfer, and tool life. Adjust for water hardness and ambient conditions to prevent residues or bacteria growth.
- Lubricity and cooling performance: Consider the machining operations you perform. Higher lubricity supports aggressive cutting and heavy chip loads, while effective cooling helps minimize thermal distortion and tool wear during long cycles.
- Material compatibility: Ensure the coolant is compatible with the alloys you work with (steel, aluminum, titanium, etc.). Some formulas perform better with aluminum or stainless steel and may require different concentrations.
- Health, safety, and environmental impact: Low-odor and low-mist options improve worker comfort and air quality. Look for formulations that are biodegradable or recyclable and free of harmful chlorinated compounds when possible.
- Maintenance and equipment compatibility: Some products are designed for misting systems, while others are better suited for flood or flood-mlood configurations. Consider nozzle types, suction, and the ability to prevent tramp oil buildup in sumps.
- Tool wear and maintenance: Evaluate claims about extended tool life, reduced tool wear, and smoother chip evacuation. Reviews or supplier data can help assess real-world performance.
- Cost and usage rate: Concentrated formulas often offer cost advantages. Estimate annual usage based on your machining hours and intended dilution to gauge long-term value.
- Environmental and disposal considerations: Select fluids that align with your shop’s waste management policies and local regulations for disposal and recycling.
