How to Choose the Right Size for Carbide Reversible Knives

Selecting the correct size for Carbide Reversible Knives is crucial to achieving optimal performance in various machining applications. The choice depends on the specific requirements of the task, the material being processed, and the capabilities of the machine. Below are the key factors to consider when determining the right size for carbide reversible knives.

1. Length of the Knife

Carbide reversible knives come in various lengths, typically ranging from 12mm to 50mm. The length you choose depends on the type of operation:

• 12mm - 20mm: Best suited for precision tasks and smaller workpieces where high accuracy is required.
• 30mm - 50mm: More suitable for larger cuts or roughing operations where material removal is the priority.

2. Width of the Knife

The width of the knives generally falls between 12mm and 15mm. This dimension influences the depth of cut:

• Narrower Knives (12mm): These are ideal for finishing tasks, providing a smooth surface and finer cuts.
• Wider Knives (15mm): These are designed for more aggressive material removal in roughing operations.

3. Thickness of the Knife

Knife thickness is another critical consideration, with common options ranging from 1.5mm to 2.5mm:

• 1.5mm: Thin knives are ideal for light-duty operations and soft materials, such as softwood, where precision and surface finish are priorities.
• 2.0mm - 2.5mm: Thicker knives are more robust, offering better durability for heavy-duty tasks involving harder materials like hardwoods or composite materials.

4. Cutting Edge Angle

The cutting edge angle of carbide reversible knives is generally between 35° and 55°. This angle affects the cutting force and chip formation:

• Smaller Angles: Provide a sharper edge, ideal for softer materials and detailed cutting.
• Larger Angles: Offer more strength and durability, suited for harder materials but may result in a rougher finish.

5. Compatibility with Equipment

It's important to ensure that the knife size is compatible with the machine and cutting tool holder. Many machine manufacturers specify the recommended knife dimensions, so always refer to the equipment manual for guidance.

Conclusion

Choosing the right size for carbide reversible knives is a balance between the machining operation, the material being processed, and the machine's capacity. In general:

• Smaller knives are ideal for finishing and precision tasks.
• Larger knives are better suited for roughing and high-volume material removal.
