霸刀分享-数控刀片（刀粒）字母代号统称含义
数控刀具字母代号通常包含了关于刀具形状、后角、公差、孔/断屑槽符号等信息。以下是对这些字母代号含义的详细解释：
1. 第一位字母：代表刀片的形状，公制与英制系统中相同的形状用相同的字母表示。例如，H代表6角形120°，O代表8角形135°，P代表5角形108°，S代表四方形90°，T代表3角形60°，C代表菱形80°，D代表菱形55°，E代表菱形75°，F代表菱形50°，M代表菱形86°，V代表菱形35°，W代表6角形80°，L代表长方形90°，A代表平行四边形顶角85°，B代表平行四边形顶角82°，K代表平行四边形顶角55°，R代表圆形。
2. 第二位字母：代表刀片后角，公制与英制系统中相同的后角用相同的字母表示。例如，A代表3°，B代表5°，C代表7°，D代表15°，E代表20°，F代表25°，G代表30°，N代表0°，P代表11°。
3. 第三位字母：代表刀片的公差，公制与英制系统中相同的公差用相同的字母表示。需要注意的是，具体的公差值会根据刀片尺寸的不同而有所变化。
4. 第四位字母：代表孔/断屑槽符号。这个种类较多，具体含义需要查阅刀具样本。一般来说，外圆刀片常用G（有孔，双面带断屑槽），镗孔刀片常用T（有孔，且单埋头孔，单面有断屑槽）。
以上就是数控刀具字母代号的主要含义。了解这些代号可以帮助用户更好地选择和使用数控刀具。
Ba Dao Shares - The General Meaning of the letter codes of CNC Blades (tool grains)
The letter codes of CNC tools usually contain information about the tool shape, relief Angle, tolerance, hole/chip-breaking groove symbols, etc. The following is a detailed explanation of the meanings of these letter codes:
1. The first letter: It represents the shape of the blade. In the metric and imperial systems, the same shape is represented by the same letter. For instance, H represents a hexagon at 120°, O at 135°, P at 108°, S at 90°, T at 60°, C at 80°, D at 55°, E at 75°, F at 50°, M at 86°, V at 35°, and W at 80°. L represents A rectangle at 90°, A represents the apex Angle of a parallelogram at 85°, B represents the apex Angle of a parallelogram at 82°, K represents the apex Angle of a parallelogram at 55°, and R represents a circle.
2. The second letter: It represents the relief Angle of the blade. In both metric and imperial systems, the same relief Angle is indicated by the same letter. For instance, A represents 3°, B represents 5°, C represents 7°, D represents 15°, E represents 20°, F represents 25°, G represents 30°, N represents 0°, and P represents 11°.
3. The third letter: It represents the tolerance of the blade. In metric and imperial systems, the same tolerance is indicated by the same letter. It should be noted that the specific tolerance value may vary depending on the size of the blade.
4. The fourth letter: Represents the symbol of the hole/chip-breaking groove. There are many types of this. For specific meanings, you need to refer to the tool samples. Generally speaking, G (with holes and double-sided chip-breaking grooves) is commonly used for cylindrical inserts, while T (with holes and single counterboring holes, and single-sided chip-breaking grooves) is commonly used for boring inserts.
The above is the main meaning of the letter code for CNC tools. Understanding these codes can help users better select and use CNC tools.
