How to choose tungsten steel milling cutter

Tungsten steel milling cutter is a commonly used tool, which plays an important role in cutting and machining metal materials. When choosing a tungsten steel mill, several factors need to be considered, such as the material, tool geometry and cutting conditions. This article will describe how to choose a suitable tungsten steel milling cutter.

I. Materials

The selection of tungsten steel milling cutter must be based on the workpiece material and the part to be processed to choose the appropriate cutter shape and material. Different tool shapes and materials are suitable for cutting different materials.

1. Material hardness

Tungsten steel milling cutter is suitable for cutting on high-hardness materials, such as steel, stainless steel, alloys, etc., while cutting on low-hardness materials will waste the cutting edge and shorten the life of the tool.

2. Thermal sensitivity of materials

For heat sensitive materials that are easy to deform and deteriorate, such as aluminum, cemented carbide, etc., tungsten steel milling cutter is easy to heat deformation and is not suitable for long-term use.

3. Material nature

Tungsten steel milling cutter is suitable for metal and steel milling cutting, and for ceramics, stainless steel, graphite and other materials, different head materials and geometry will produce different effects, so it needs to be selected according to the specific situation.

Second, tool geometry

Different tool geometers are suitable for different cutting and machining needs. Here are some common geometries:

1. Surface milling: universal, suitable for a variety of processing operations;

2. Cone milling: suitable for processing bevel, cone and other materials;

3. Cutting milling cutter: suitable for flat surface, wall, slotting and platform processing;

4. Long edge milling cutter: suitable for processing deeper grooves;

5. Slot milling cutter: suitable for cutting narrow slots and deep slots;

6. Prototype milling cutter: widely used in non-standard shape processing.

Depending on different cutting needs and machining operations, choosing the right tool geometry helps to improve cutting efficiency.

Third, cutting conditions

Cutting conditions are another factor to consider, namely the speed, feed and depth of the tool.

1. Tool speed

The cutting speed of tungsten steel milling cutter depends on factors such as cutting material, tool shape and process conditions. When selecting a tool, it is necessary to select the appropriate tool according to the specific cutting materials and process parameters, such as cutting speed, number of teeth, coolant, etc.

2. Feed quantity

The feed is the distance the tool moves per unit time. Choosing the right feed rate helps to improve cutting efficiency and avoid cutting failure.

Step 3: Depth

The depth depends on factors such as the hardness of the material to be machined and the shape of the tool. Choosing the right tool according to different depth requirements and hardness levels can improve cutting efficiency and extend tool life.

To sum up, the choice of suitable tungsten steel milling cutter needs to consider a number of factors. First of all, according to the workpiece material, choose the appropriate material, tool shape and geometry to meet different cutting and processing needs. In addition, cutting parameters also need to be selected according to the specific situation to ensure good cutting efficiency and tool life performance.
