- Material classification
High-speed steel is a high-grade steel used in the manufacture of cutting tools, with high wear resistance, heat resistance and hardness, suitable for a variety of materials processing.
Carbide
Cemented carbide cutting tools are made of tungsten, tungsten, cobalt, titanium and other metals, with very high wear resistance and compression resistance, suitable for machining high hardness, high wear-resistant materials.
Ceramic
Ceramic tools have high hardness, high toughness, high corrosion resistance and high temperature stability, suitable for machining high hardness, high wear-resistant materials, and at the same time have excellent surface quality.
Diamond
Diamond tools are widely used for machining glass, ceramics, non-metallic materials and other high hardness materials due to their extremely high hardness and wear resistance.
CBN
CBN tools are harder than diamond tools and are suitable for machining materials with high hardness and not easy to cut, enabling high-quality machining and excellent surface quality after machining.
- Selection basis
Cutting material
The first thing to consider is the type of material to be processed, because different materials have different hardness, cutting performance and wear resistance, and need to choose the tool suitable for the material.
Cutting type
Different machining needs may require different types of tools, such as drilling tools, milling tools, turning tools, etc. Hole diameter, depth of cut and trajectory etc. also need to be considered when selecting the tool.
Cutting speed and feed rate
In CNC machining, cutting speed and feed rate will directly affect the cutting effect and machining efficiency. Choosing the right tool requires the ability to adapt to the required cutting speed and feed rate.
Tool shape and size
The shape and size of the tool is also a key factor in the selection. The shape of the tool should be adapted to the requirements of the machining shape, and the size of the tool should match the size and requirements of the machined part.
Tool material and coating
The material and coating of the tool determine its hardness, wear resistance and cutting performance. Coatings provide wear resistance and lubrication on the tool surface and extend tool life.
Cutting forces and vibration control
The effects of cutting forces and vibration on machining need to be considered when using cutting tools. Choosing the right tool can reduce vibration and cutting forces and improve machining quality and efficiency.
Cost effectiveness
Cost-effectiveness also needs to be considered when selecting a tool, including the price, performance and life of the tool. Higher quality tools may be more expensive, but may be more advantageous in terms of service life and machining results.
In summary, when selecting a CNC tool, a combination of material, type of cut, speed requirements, shape and size, materials and coatings, cutting forces and vibration control, as well as cost-effectiveness need to be considered in order to select the right tool for a particular machining requirement.
