A Deep Dive into Normantherm’s CUT200 Vacuum Brazing Furnace

In the modern world of advanced materials and ultra-precise tooling, the need for reliable, consistent, and high-quality brazing is greater than ever. Enter Normantherm’s CUT200 Vacuum Brazing Furnace—a precision-engineered solution tailored for manufacturing and repairing diamond tools, PCD/PCBN inserts, CNC cutting tools, and metal alloys used in high-performance industries. Built for efficiency and repeatability, the CUT200 is more than just a furnace; it's a tool for innovation. 

 

Overview of the CUT200 Vacuum Brazing Furnace 
Normantherm’s CUT200 is purpose-built for vacuum brazing of high-performance components, offering technical parameters that support both prototyping and industrial-scale production.

Key Features That Make the CUT200 Stand Out 

1. Ultra-High Vacuum Capability 

With an ultimate vacuum of 6.0×10⁻⁴ Pa, the CUT200 eliminates the presence of air and reactive gases during the brazing cycle. This ensures: 

 

• Zero oxidation
• Clean brazing interfaces
• Enhanced mechanical bonding

This vacuum level is especially critical for brazing carbide or diamond tools, which are sensitive to contamination at high temperatures. 

2. Uniform Heating 

The cylindrical heating zone (200 mm diameter x 400 mm length) ensures a homogeneous thermal profile, reducing the risk of thermal distortion and ensuring joint consistency across complex geometries. 

3. Temperature Precision up to 1000°C 

 

• Stepwise ramp-up and soak cycles
• Rapid or slow cool-downs depending on materials
• EPrecise melting of brazing alloys (like Ag-Cu, Ni-Cr, or Au-based fillers)

 

Our systems provide:
1.High vacuum levels to prevent oxidation and eliminate the need for flux. 2.Precise temperature control to manage narrow brazing windows.
3.Uniform heat distribution for consistent quality across all components.
4.Fully automated cycles for process repeatability and reduced labor.
5.Customizable configurations to meet specific part sizes, volumes, and production needs. 

4. Touchscreen Operation and Automation
The built-in control system includes: 

 

• PLC-based programmable cycles
• Real-time temperature and vacuum display
• Error detection and user-friendly interface

What Materials Can Be Brazed with CUT200

1. Diamond Tools: 
 

Used in drilling, cutting, and grinding—diamond tools require careful brazing to ensure retention without damaging the diamond structure. Vacuum brazing offers superior wetting and adhesion.

2. PCD (Polycrystalline Diamond) and PCBN (Cubic Boron Nitride) Tools:h 

These tools are highly durable and used in high-speed machining. The CUT200 ensures strong joints between inserts and shanks without causing phase degradation. 

3. Carbide Inserts and CNC Tools: 

Brazing carbide inserts into tool holders with precision is crucial in CNC operations. The CUT200's vacuum chamber avoids thermal cracks and ensures seamless bonding.. 

4. Metal Alloys: 

Joining dissimilar alloys like titanium, stainless steel, or Inconel is a common requirement in aerospace and energy sectors. CUT200 allows such combinations without flux residues or porosity.. 

Brazing Filler Metals: Compatibility with CUT200 

The CUT200 supports a range of brazing filler metals including: 

 
All these materials behave best under vacuum, allowing their wetting characteristics and capillary action to perform at optimal levels. 

Customization Options and Flexibility Normantherm understands that each industrial application is unique. That’s why the CUT200 can be customized in: 

 

• Chamber dimensions
• Heating elements (Mo, graphite, or alloy-based)
• Control systems (touchscreen PLC or PC-based HMI)
• Cooling systems (air, water, or oil-assisted)

You can also request multi-zone heating, data logging, or automatic venting features for process automation. 
The CUT200 is designed with energy-saving insulation, high-quality vacuum seals, and a maintenance-friendly architecture. The system minimizes power wastage during long brazing cycles and ensures stable performance across thousands of operational hours.
