Before Brazing Tungsten Carbide Saw Blades — The Foundation of Precision Cutting Tools

In the tool and die manufacturing industry, the performance of a saw blade is defined by the strength and precision of its joints. Tungsten carbide saw blades, widely used in metal cutting, wood processing, and machining applications, require flawless bonding between carbide tips and steel bases to ensure durability and sharpness.

At Normantherm, we understand that every precise cut begins with an exacting process — starting before brazing even begins.

The Role of Pre-Brazing Preparation

The pre-brazing stage is critical to achieving high-quality bonding. This phase involves:

• Cleaning and aligning tungsten carbide tips.
• Removing surface contaminants for optimal wetting.
• Ensuring proper fitment between steel base and carbide segments.

Even a minor imperfection in this stage can lead to uneven bonding, joint failure, or reduced tool life. Normantherm’s vacuum furnace systems are designed to control these variables with accuracy, guaranteeing consistency at every production stage.

Vacuum Brazing: Redefining Quality for Cutting Tools

Once prepared, the saw blades undergo vacuum brazing — a process that bonds the tungsten carbide to steel without oxidation or flux contamination. The benefits include:

- Oxidation-free joints ensuring material purity.
- Uniform temperature control preventing deformation.
- High bond strength, essential for high-speed cutting.
- Enhanced tool durability and performance.

Normantherm’s precision furnaces maintain exact temperature profiles and vacuum levels, ensuring a strong metallurgical bond between materials — vital for saw blades used in heavy-duty cutting environments.
