霸刀分享-数控刀具上的字母解释大全
数控刀具上的字母通常用来表示刀具的特定属性，如形状、后角角度、精度等级、前刃面及中心孔型等。以下是这些字母的具体含义：
1. 形状：第一个字母一般表示数控刀片的形状，常用的通常有H、O、P、S、T、C、D和E，分别是正六角形、正八角形、正五角形、正方形、菱形80度顶角、菱形55度顶角和菱形75度顶角。
2. 后角角度：第二个字母表示刀片后角角度，常用的字母通常为A、B、C、D、E、F、G、O，A表示后角角度为3°，B为5°，C为7°，D为15°，E为20°，F为25°，G为30°，N为0°，P为11°，O表示其他后角角度。
3. 精度等级：第三个字母表示刀片精度等级，最常用的是M级与G级，一般粗加工及半精加工精加工刀片都是M级，精密加工用刀片以及超硬刀片一般都是G级。
4. 前刃面及中心孔型：第四个字母表示刀片的前刃面及中心孔型（槽和孔）。
5. 尺寸型号：数字总共有6个，分为三组，第一组表示刀片刃长，第二组表示刀片厚度，第三组表示刀片刀尖圆弧半径。
6. 材质：-后面的字母表示刀片的材质，数控刀片的材质很多，不同的材质生产出来的产品自然也会有所不同，因此在求购数控刀片的时候一定要注意选择刀片的材质，不同的材质价格也是截然不同的。一般都用两位字母来表示，大多是合金，P表示一般钢，M表示不锈钢，K表示灰口铸铁或者球墨铸铁，N表示铝/废铁金属，S表示耐热合金或者钛合金，H表示高硬度材等。
以上就是数控刀具上各个字母所代表的含义。需要注意的是，在选择刀具的角度时，需要考虑多种因素的影响，如工件材料、刀具材料、加工性质（粗、精加工）等，必须根据具体情况合理选择。
Ba Dao Sharing - A Comprehensive Guide to Letter Explanations on CNC Tools
The letters on CNC tools are usually used to indicate specific attributes of the tools, such as shape, relief Angle, precision grade, rake face and center hole type, etc. The following are the specific meanings of these letters :
1. Shape: The first letter generally indicates the shape of the CNC blade. Commonly used ones usually include H, O, P, S, T, C, D and E, which are respectively regular hexagon, regular octagon, regular pentagon, square, rhombus with an 80-degree top Angle, rhombus with a 55-degree top Angle and rhombus with a 75-degree top Angle.
2. Relief Angle: The second letter represents the relief Angle of the blade. Commonly used letters are usually A, B, C, D, E, F, G, and O. A indicates a relief Angle of 3°, B of 5°, C of 7°, D of 15°, E of 20°, F of 25°, G of 30°, N of 0°, P of 11°, and O indicates other relief angles.
3. Precision grade: The third letter indicates the precision grade of the blade. The most commonly used ones are M grade and G grade. Generally, rough machining and semi-finish machining blades are of M grade, while precision machining blades and super-hard blades are usually of G grade.
4. Front edge face and center hole type: The fourth letter indicates the front edge face and center hole type (groove and hole) of the blade.
5. Size and Model: There are a total of 6 numbers, which are divided into three groups. The first group indicates the blade length, the second group indicates the blade thickness, and the third group indicates the radius of the blade tip arc.
6. Material: The letter following the blade indicates the material of the blade. There are many materials for CNC blades, and products made from different materials will naturally vary. Therefore, when purchasing CNC blades, it is essential to pay attention to choosing the material of the blade, as the prices of different materials are also completely different. Generally, it is represented by two letters, mostly alloys. P stands for common steel, M for stainless steel, K for gray cast iron or ductile iron, N for aluminum/scrap iron metal, S for heat-resistant alloys or titanium alloys, and H for high-hardness materials, etc.
The above are the meanings represented by each letter on the CNC tool. It should be noted that when choosing the Angle of the cutting tool, the influence of multiple factors needs to be considered, such as the material of the workpiece, the material of the cutting tool, and the nature of the processing (rough or finish machining), etc. A reasonable selection must be made based on specific circumstances.
