Master serial production in difficult alloys. Minnexon Multi-Form Thread Mills eliminate work hardening in Titanium and ensure consistent gauging in Kovar and Nickel alloys.
- Internal and External: Safely machine both internal and external threads.
- Left and Right Hand: You can create right-hand or left-hand threads simply by changing the CNC program.
The Challenge: Scaling Up Production in “Sticky” Metals
Prototyping in Titanium or Kovar is one thing; running thousands of parts is another. When you move from testing to serial production threading, standard tools often fail due to the unique properties of these materials:
- Titanium Work Hardening: Repeated passes with single-point tools generate heat, causing Titanium surfaces to harden instantly, destroying the tool’s edge.
- Galling in Nickel Alloys: The material welds itself to the cutter, leading to poor thread finish and thread gauging failures.
- Kovar Abrasiveness: Machining Kovar glass-to-metal seal components requires tools that can withstand high abrasion while cutting gummy material.
You need a tool that cuts cleanly, quickly, and stays cool. You need the Minnexon Multi-Form solution.
The Minnexon Solution: One-Pass Stability
Our Solid Carbide Multi-Form Thread Mills are engineered to solve the specific behaviors of these aerospace and electronic alloys.
1. Eliminate Work Hardening (The “One-Pass” Strategy)
The biggest enemy in machining Titanium Gr5 is heat buildup.
- How we solve it: Our multi-form design cuts the full thread depth along the entire axis simultaneously.
- The Benefit: By utilizing a single-pass helical interpolation, we minimize the contact time between the tool and the part. This prevents the material from hardening, ensuring a clean cut and dramatically extending tool life.
2. The “Golden Coating” for Kovar & Nickel
Kovar and Nickel-based alloys are notoriously “gummy” yet abrasive.
- Anti-Adhesion Barrier: Our strategic Golden Coating prevents the material from welding to the cutting flutes (built-up edge). This is critical for maintaining thread tolerance in Kovar.
- Thermal Shock Resistance: The coating protects the carbide substrate from the thermal shock of entering and exiting the cut, which is common in interrupted cutting of superalloys.
3. Rigid Design for Consistent Gauging
When machining thousands of connectors or implants, every thread must pass the Go/No-Go gauge.
- Reduced Deflection: Unlike single-point tools, our multi-form cutters have a larger core diameter. This rigidity eliminates the “tapered thread” issue often seen when thread milling deep holes in alloy steel.
