Introduction to diameter specifications of end mills

End mills are available in a variety of diameter specifications to meet different machining needs. The following is a detailed description of the diameter specifications of end mills:

First, the standard range

According to national standards, the diameter of end mills usually ranges from 2 mm to 50 mm. This range covers a wide range of needs from tiny parts machining to large size parts machining.

Second, common specifications

In practice, the diameter specifications of end mills are more diverse, and the following are common:

Small Diameter End Mills (2mm to 8mm): These end mills are suitable for precision machining, such as the machining of electronic components, watch parts, molds and other tiny parts. Small diameter end mills have less cutting force during machining and can ensure high precision machining results.

Medium Diameter End Mills (10mm to 16mm): These end mills are suitable for general milling processing, such as shafts after turning, processing of small and medium-sized metal parts. Medium diameter end mills have moderate cutting force, which can ensure good machining accuracy and high machining efficiency.

Large Diameter End Mills (18mm to 50mm): These end mills are suitable for efficient machining of large-size parts, such as machine tools and lathe components. Large diameter end mills have a large cutting force during machining, which can quickly remove a large amount of material and improve machining efficiency. However, it should be noted that due to the large cutting force, the rigidity and stability of the machine tool is required to be high.

Third, special specifications

In addition to the above common specifications, there are some special specifications of end mills to meet specific processing needs. For example, some ultra-small diameter end mills (such as 1 mm, 1.5 mm, etc.) can be used in the field of microfabrication; while some ultra-large diameter end mills (such as more than 50 millimeters) may be used in the machining of heavy mechanical parts.

Fourth, the selection of recommendations

In the selection of end mill diameter, the following factors need to be considered:

Machining requirements: Select the appropriate end mill diameter according to the size, shape and accuracy requirements of the parts to be machined.

Machine performance: Ensure that the diameter of the selected end milling cutter matches the rigidity and stability of the machine tool to avoid excessive vibration and deformation in the machining process.

Cutting parameters: According to the diameter of the end milling cutter and the machining material, reasonably set the cutting parameters such as cutting speed, feed and depth of cut to get the best machining effect.

Tool cost: under the premise of ensuring the processing quality, choose the cost-effective diameter of end milling cutter to reduce the processing cost.

Fifth, summary

End mills have a variety of diameter specifications, covering a wide range of needs from tiny parts machining to large-size parts machining. When selecting the diameter of the end mill, it is necessary to comprehensively consider the processing requirements, machine tool performance, cutting parameters and tool cost and other factors to ensure that the best machining results are obtained.
