Detailed Introduction to Carbide Brazed Tip Geometry and Design
What is Carbide Brazed Tip Geometry?
La géométrie des pointes brasées en carbure se réfère à la forme, aux angles et aux dimensions de l'arête de coupe et des surfaces de la pointe. Les paramètres géométriques clés sont les suivants
- Angle d'inclinaison : L'angle entre l'arête de coupe et la surface de la pièce. Il influence la formation de copeaux et la force de coupe.
- Angle de décharge : L'angle entre le flanc de l'outil et la surface de la pièce, empêchant le frottement et réduisant la friction.
- Angle du bord de coupe : L'angle formé par l'intersection des faces du râteau et du flanc, qui affecte la solidité et la résistance à l'usure de l'outil.
- Rayon de l'angle : L'arête arrondie à la pointe de l'outil, qui a un impact sur la finition de la surface et la durée de vie de l'outil.
How Does Design Influence Cutting Performance?
The design of a carbide brazed tip encompasses its overall structure, including the placement of the cutting edges, the distribution of material, and any additional features such as chip breakers or coatings. These design elements work in harmony with the geometry to optimize cutting performance. Key design aspects include:
