Structural Types of End Mills<\/h1>\n

Classified by the Number of Cutting Edges:<\/h2>\n

The cylindrical surface and end face of an freze<\/a> usually have cutting edges distributed on them, which can engage in cutting simultaneously or individually. Based on the number of blades, end mills can be categorized into double-edge, triple-edge, quadruple-edge, and multi-edge types.<\/p>\n

Widely used, applicable to slot machining, side machining, and step surface machining, etc. In addition, it can be used in all situations of rough machining, semi-finishing, and finishing.<\/p>\n

Tapered end mill\"\"<\/h3>\n

Used for conical surface machining after general cutting, such as mold draft angle machining and concave portion machining, etc.<\/p>\n

Gear-type end mill<\/h3>\n

\"\"<\/p>\n

The cutting edge is wavy, producing fine chips, with low cutting force, suitable for rough machining, not suitable for finish machining.<\/p>\n

A forming blade is a cutting edge that is shaped to match the contours of the workpiece being machined. Special shapes typically need to be custom-made based on the product’s shape and dimensions.<\/p>\n

Key Points for Selecting End Mills<\/h1>\n

When using an end mill, multiple factors need to be considered to ensure machining efficiency, precision, and tool life. Here are some key considerations:<\/p>\n

\u2460 Material of the workpiece: Different materials (such as steel, cast iron, aluminum alloy, plastic, composite materials, etc.) require tools with different characteristics. For example, when machining aluminum alloy, a specialized aluminum end mill can be chosen, which typically has good chip evacuation and heat resistance; when machining high-hardness materials, a carbide tool with a high-wear-resistant coating should be selected.<\/p>\n

\u2461 Machining form and precision requirements: Choose the shape and number of cutting edges based on the shape of the machining surface (plane, slot, contour, etc.) and the required surface roughness. For instance, a ball nose end mill is suitable for complex surface machining, while a flat or rounded end mill is suitable for plane and edge machining. For high-precision machining, choose an end mill with higher arc precision.<\/p>\n

\u2462 Helix angle of the end mill: The helix angle affects cutting efficiency and tool life. When machining materials with poor thermal conductivity (such as stainless steel), a large helix angle can improve chip evacuation and heat dissipation, extending tool life. For thin-walled workpieces or machining with poor rigidity, a small helix angle can reduce cutting forces and avoid workpiece deformation.<\/p>\n

 <\/p>\n

 <\/p>\n

\u2463 Tool material and coating: Carbide is the most commonly used tool material. For different working conditions, selecting the appropriate carbide grade and coating (such as TiCN, TiAlN, etc.) can enhance tool performance. High-speed steel (HSS) is suitable for low-speed and low-hardness material machining, while carbide is more suitable for high-speed and high-hardness material machining.<\/p>\n

\u2464 Tool structure: Solid, brazed, and indexable tools each have their advantages. Solid tools have good rigidity and are suitable for precision machining; brazed and indexable tools are convenient for blade replacement and are suitable for mass production.<\/p>\n

\u2465 Number of flutes and shank structure: The number of flutes affects the tool rigidity and chip flute size. When the workpiece rigidity is low, it is advisable to choose a tool with fewer flutes to improve chip evacuation; the shank design (standard, long neck, tapered neck) needs to be selected based on the machining depth and workpiece shape. Tapered neck end mills provide better rigidity and machining accuracy.<\/p>\n

 <\/p>\n

\u2466 Tool length: Under the condition of meeting the machining requirements, choose the shortest tool length as much as possible to increase stability, reduce vibration, and thereby improve the quality of machining.<\/p>\n

\u2467 Cost-effectiveness: Consider the tool cost and machining efficiency comprehensively and choose a cost-effective solution.<\/p>\n

In summary, the selection of end mills is a process of comprehensive consideration, involving workpiece material, machining requirements, tool performance, cost-effectiveness, and other aspects. Correct selection can greatly improve machining efficiency, reduce costs, and ensure machining quality.<\/p>\n
