Oemeta Novamet: The "Universal" Coolant for Aerospace & Medical
The Oemeta Novamet Series is the premier choice for high-mix job shops and precision manufacturers requiring a single fluid to machine every metal. While the formulation is German-engineered by Oemeta Chemische Werke GmbH, the fluid is manufactured in Salt Lake City, Utah and stocked in US Distribution Centers. This hybrid approach provides American facilities with advanced "multi-metal" technology without the risk of import delays.
Why Shops Choose the Novamet Series
The Novamet platform (featuring flagships like Novamet 910 B and Novamet 875) is engineered to solve the critical challenges of machining sensitive alloys: part staining, high-pressure foaming, and short tool life in exotic metals.
1. True Multi-Metal Compatibility
The Problem: Standard coolants are often aggressive, causing "staining" or "pitting" on sensitive Aluminum (7000 series) and Yellow Metals (Brass, Bronze, Copper). The Novamet Solution: Novamet is engineered with specialized non-ferrous inhibitors. It allows you to machine Steel, Titanium, Inconel, Aluminum, and Brass in the same sump without fear of galvanic corrosion or staining expensive finished parts.
2. High-Pressure (Through-Spindle) Performance
The Problem: Modern CNCs run "Through-Spindle Coolant" at 1,000+ PSI. Standard fluids turn into a foam bath under this pressure, triggering sensors to shut down the machine. The Novamet Solution: Novamet utilizes Low-Foam Technology. It remains stable and liquid even under extreme high-pressure delivery, ensuring consistent cooling at the cutting edge without cavitating pumps or overflowing tanks.
3. Extreme Lubricity for Exotics
The Problem: Titanium and Inconel generate immense heat, welding chips to the tool and destroying inserts. The Novamet Solution: Novamet features a high content of Advanced Ester Lubricity. Unlike mineral oil alone, these esters provide a "polar bond" to the metal surface, dramatically extending tool life in aerospace alloys and medical-grade stainless steel (304/316).
Technical Insights: The Real Cost & Conversion
What to expect when switching to Novamet.
The "Real" Cost of Ownership
Novamet is a premium fluid, but it pays for itself in tool savings and makeup rates. Because of its high stability, most shops run a lean 1% to 2% makeup rate. Furthermore, by eliminating the need for "Process Cleaners" (to wash off sticky residues) and reducing tool changes on titanium, the cost-per-part drops significantly.
Machine Compatibility
Novamet is designed to be universally safe for modern machine tools.
- Seal Safe: Compatible with all standard CNC seals and way cover wipers.
- Glass & Paint: The advanced chemistry prevents the etching of safety glass and preserves the epoxy paint on machine enclosures.
The "Zero-Downtime" Conversion Protocol
Switching to Oemeta does not require days of downtime.
- Clean While You Run: Add Oemeta System Cleaner to your old coolant 24 hours before draining.
- Drain & Rinse: Remove chips and rinse with a 1% Novamet solution.
- Charge: Fill with fresh Novamet. (Contact our Fluid Lab for a dedicated step-by-step conversion guide for your specific central system.)
Tech Tool Support & Availability
When you source Oemeta products through Tech Tool, you gain a national fluid management partner:
- Rapid Deployment: Inventory is stocked in US Distribution Centers (Pails, Drums, and Totes) for immediate dispatch to facilities nationwide.
- Fluid Lab Access: Get free access to our Fluid Maintenance Lab for routine testing to track concentration and pH.
- Compliance Ready: We provide dedicated SDS compliance support and "Aerospace Approval" documentation (where applicable) for quality managers.
Recommended Equipment
To maintain the high-performance characteristics of Novamet, precise concentration is key.
- Mixing: Use the Dosatron D14MZ10 (1–10%) for accurate initial charging.
- Verification: Check daily with an Industrial Refractometer (0–18% Scale).
- Maintenance: Remove tramp oil with a Nimatic Belt Skimmer to keep the emulsion oxygenated.
Frequently Asked Questions
Will Novamet stain Aluminum or Brass?
A: No. Novamet is specifically formulated as a "Non-Staining" universal fluid. It is safe for use on sensitive aerospace aluminum (7000 series), copper, brass, and bronze, making it the ideal choice for "High-Mix" job shops.
Is Novamet safe for operators?
A: Yes. Like the Unimet series, Novamet is formulated with operator safety in mind. Many formulas (like Novamet 910) are Free of Bactericides, Boron, and Formaldehyde, reducing the risk of dermatitis even in high-production environments.
What is the mix ratio for Novamet?
A: Because Novamet is used on tougher metals, we recommend a slightly richer mix.
- General Aluminum/Steel: 6% to 8%
- Titanium/Inconel: 8% to 12% (for maximum tool life). Always verify with a refractometer (Refractive Index typically 1.0 – 1.2 for Novamet series).
