Hemispherical End Mills

What is a Hemispherical End Mill? 

Definition and Usage 

A hemispherical end mill is a cutting tool primarily used in machining to create concave or rounded shapes on a workpiece. Thanks to its unique shape, this end mill enables precise cuts, especially in hard-to-reach areas. It is often used in contouring or cavity milling. 

Applications in Machining 

Hemispherical end mills are particularly suited for precision machining applications, such as mold and tool making. They can be used on various materials, including metals, plastics, and composites. With their specific design, these tools allow for precise cuts, especially at the center of parts, facilitating access to challenging areas. Hemispherical series end mills, whether of normal or extra-long length, enable efficient milling operations, optimizing work time. 

Advantages of Hemispherical End Mills 

The advantages of hemispherical end mills include their ability to achieve high-quality finishes and their efficiency in material removal. These tools also allow working at various angles due to their tooth geometry and helix, promoting better chip evacuation. Using materials like micrograin carbide or HSSCo8, the end mills offer increased durability and excellent value for money.

Criteria for Choosing a Hemispherical End Mill

When choosing a hemispherical end mill, several criteria must be considered:

• Diameter and Length: It is crucial to choose a diameter that matches the desired depth and type of cut.
• Number of Teeth (Z): The higher the number of teeth, the faster the cut, but this can also result in a greater load on the tool.
• Material Type: The material of the end mill must be suitable for the type of workpiece to be machined, whether it is carbide, steel, or composite materials.

• Cooling System: Using a cooling system can improve the lifespan of the end mill and the quality of the cut by cooling the tool during machining.

FAQ on Hemispherical End Mills

What is the difference between Z2 and Z4? 

Hemispherical end mills Z2 have fewer teeth compared to Z4, making them more suitable for deeper cuts with less stress. The Z4, with their improved tooth geometry, allow for faster cuts and are ideal for finishing. 

How to choose the right size of end mill? 

The choice of end mill size depends on the specific application and the material to be machined. It is essential to consider the diameter, length of the end mill, and the desired depth of cut to select the right model. 

Are hemispherical end mills suitable for all materials? 

While hemispherical end mills are versatile and can be used on various materials, it is important to choose the appropriate end mill based on the material, such as carbide end mills for hard metals or coated models for plastics.
