How to choose CNC blade?

When choosing a CNC blade, it is usually necessary to consider the following key factors:

1. Processing materials

Different materials require different CNC blade materials and geometric shapes. For example, processing steel parts usually uses carbide blades, while processing aluminum alloys may be more suitable for diamond-coated blades. The hardness, toughness and thermal conductivity of the material will affect the choice of blade.

2. Processing technology

Different processing processes such as turning, milling and drilling require the corresponding blade type, rough processing requires a blade with strong cutting ability and wear resistance, while finishing requires better surface quality and precision.

3. Cutting parameters

Cutting speed, feed rate and cutting depth, these parameters will affect the load and wear of the CNC blade, thus determining the material and geometry of the blade, high cutting speed usually requires a high temperature resistant blade material.

4. Blade geometry

Tip radius: affects cutting force, surface quality and tool life. Small radius is suitable for finishing, large radius is suitable for roughing. Front and back angles: A large front Angle is suitable for cutting soft materials, while a large back Angle helps reduce friction and improve surface quality.

5. Blade coating

Common coatings such as TiN (titanium nitride), TiCN (titanium carbonitride), Al2O3 (alumina), etc., can improve the wear resistance, anti-viscosity and cutting performance of the blade.

6. Cutter brand and quality

Well-known brands are usually more guaranteed in terms of quality and performance, but the price can be relatively high.

7. Cost

Under the premise of meeting the processing requirements, the price and life of the blade are considered to achieve the best cost performance.

8. Machine compatibility

Ensure that the selected CNC blade is compatible with the tool handle, tool holder and other components of the machine.

Taking the above factors into consideration, the appropriate CNC blade can be selected according to the specific processing tasks and requirements. If you are not sure how to choose, you can also consult the tool supplier.
