Tungsten steel ball cutting tool (cemented carbide ball head milling cutter) is a cutting tool commonly used for precision processing. Due to its high hardness, wear resistance and special geometric shape, it is widely used in complex surface processing, mold manufacturing, 3C product processing and other fields. The following is a detailed introduction to the tungsten steel ball cutting knife:
**1. Structure and Materials**
- **Material**:
- The main body is cemented carbide (tungsten steel), the main components are tungsten carbide (WC) and cobalt (Co), the hardness can reach HRA above 90 and excellent wear resistance.
- Some high-end tools are coated (such as TiAlN, DLC, etc.) on the surface to further improve high temperature resistance and life.
- **Geometric Shapes**:
- **Spherical cutter head**: The blade is hemispherical, suitable for processing complex curved surfaces, grooves, 3D contours, etc.
- **Number of blades**: Common 2-edge, 3-edge or 4-edge designs. The more blades, the higher the processing efficiency, but the chip removal capability may be reduced.
**2. Application Areas**
- **Mold processing**: Precision injection molds, die-casting mold cavity and parting surface processing.
- **Aerospace**: Curved surface processing of titanium alloy and high-temperature alloy components.
- **3C Electronics**: Fine carving and processing of mobile phone/computer shells and precision structural parts.
- **Medical Devices**: Complex surface processing of artificial joints and surgical instruments.
- **Automotive manufacturing**: Precision trimming of engine parts and gearboxes.
**3. Core Advantages**
- **High precision**: The ball head design reduces cutting vibration and is suitable for micron-level finishing.
- **Strong wear resistance**: Tungsten steel material can keep the edge sharp for a long time and extend the service life.
- **Adapting to complex curved surfaces**: The spherical blade can contact the workpiece at multiple angles, reducing the number of tool changes.
- **Efficient machining**: Supports high-speed cutting (HSM) and improves efficiency with high-speed machine tools.
**4. Key parameters for selection**
- **Diameter range**: Commonly 0.1mm~20mm, small diameter (such as below 0.5mm) is used for ultra-precision processing.
- **Blade length and handle diameter**: It must be selected according to the processing depth and machine tool clamping ability.
- **Coating Type**:
- **No coating**: Universal processing.
- **TiN/TiAlN**: High temperature resistance, suitable for high-speed cutting.
- **Diamond Coating**: Used for high-gloss processing of non-ferrous metals (such as aluminum alloys, copper).
- **Helix angle**: affects chip removal and cutting force, usually 30°~45°.
