Straight end mills and end mills are two commonly used cutting tools that have some differences in their appearance and applications. Even though their functions may seem similar, and the materials used to manufacture them appear to be quite different, there are distinct differences between them. Let's explore their differences.

Cutting Function and Introduction of Straight End Mills:

A straight end mill is one of the cutting tools and features a straight-shaped blade. It is usually made of aluminum alloy with hardness ranging from HRC52 to HRC65, or it can be made of materials such as high-speed steel and hard alloy. Straight end mills come in various shapes, such as flat-bottomed, V-shaped, and chamfering. They are used for woodworking, carving, milling slots, and other operations. They are commonly used for edge correction, slotting, and pocketing.

Cutting Function and Introduction of End Mills:

End mills are also a type of cutting tool and have cylindrical-shaped blades. Similar to straight end mills, they are made of aluminum alloy with hardness ranging from HRC52 to HRC65, as well as high-speed steel and hard alloy. End mills have multiple cutting edges and are commonly used for milling flat surfaces, slotting, and pocketing. Therefore, there are several differences between end mills and straight end mills.

Where are the Differences?

In terms of appearance, straight end mills have a straight shape, while end mills have cylindrical-shaped blades.

In terms of cutting methods, straight end mills use homogeneous cutting edges for cutting, while end mills rely on the rotation of the blade and the side edge for cutting.

In terms of applications, straight end mills are mainly used for woodworking, carving, and pocketing, while end mills are primarily used for metalworking, such as milling flat surfaces, slotting, and pocketing.

Applications of Straight End Mills and End Mills:

In the woodworking industry, straight end mills are more commonly used, especially those made of HRC52 materials. They can be used for edge correction, slotting, and pocketing of wood materials. End mills, with their multiple cutting edges and rotational cutting characteristics, play a significant role in the metal industry. They are used for milling metal surfaces, slotting, etc. In the metal industry, it is crucial to use sturdy end mills because they can be easily damaged if mishandled. Straight end mills can also be used for plastic processing, composite material processing, and more. End mills find applications in areas such as mold manufacturing, aerospace, and other fields.

How to Choose?

1. Consider the characteristics of the material being cut. Different materials have different hardness levels, and the required hardness of the cutting tool varies accordingly.

2. Consider the surface condition and notches after processing, as well as the required precision and efficiency. Choose the most suitable cutting tool accordingly.

3. Cutting speed is also an important factor in selecting cutting tools. For harder materials, a higher cutting speed can be used to complete the project more quickly.

Conclusion:

Straight end mills and end mills are common cutting tools that play irreplaceable roles in the cutting process. By understanding the definitions, characteristics, and application areas of straight end mills and end mills, as well as the key points for selecting cutting tools, we can better comprehend their differences and applicable ranges and make informed choices in practical applications. Whether in the woodworking industry, metalworking industry, or other fields, selecting and using straight end mills or end mills correctly can improve processing efficiency and quality and contribute to the development of various industries.
