霸刀分享-丝锥的主要种类和用途
丝锥是一种常用的螺纹加工工具，主要用于加工各种中、小尺寸的内螺纹。以下是丝锥的一些主要种类和用途：
① 手用丝锥：由碳素工具钢或合金工具钢制成，适用于手工操作进行攻丝。
② 机用丝锥：通常指高速钢磨牙丝锥，适用于在机床上攻丝，特点是刚性好、导向性佳，适合批量生产。
③ 螺母丝锥：专门用于加工螺母的内螺纹，设计上可能有所不同，以适应螺母的特殊形状和加工要求。
④ 挤压丝锥：用于金属的塑性变形加工螺纹，没有切屑产生，适用于延展性好的材料如铝合金、铜件和低碳钢等。它可以用于盲孔或通孔，加工出的螺纹孔具有较高的抗拉、抗剪强度和良好的表面粗糙度。
⑤ 直槽丝锥：特点是切削刃数等于沟槽数量乘以切削锥牙数，适用于通孔加工，切屑容易向前排除，不易缠绕，具有较高的抗折损强度和良好的切削性能。
⑥ 螺旋槽丝锥：具有螺旋沟槽，能够加工到盲孔的底部而不残留切屑，切削性能好，通孔和盲孔均可使用。切屑呈卷曲状，适用于延展性好的材料。
⑦ 刃倾角丝锥：具有刃倾角设计，使得切屑能够向下或向前排除，适用于特定材料和加工条件。
⑧ 公制粗牙丝锥、公制细牙丝锥、管螺纹丝锥等：这些是根据不同标准和螺纹类型设计的丝锥，用于加工相应类型的螺纹。
综上所述，丝锥的种类多样，适用于不同的加工需求和材料特性。在选择丝锥时，需要根据具体的加工要求和工件材料来确定最适合的类型。
Ba Dao Sharing- The main types and uses of taps
Taps are commonly used thread processing tools, mainly used for processing various medium and small-sized internal threads. The following are some of the main types and uses of taps
① Hand tap: Made of carbon tool steel or alloy tool steel, it is suitable for manual tapping operations.
② Machine taps: Generally refer to high-speed steel ground taps, which are suitable for tapping on machine tools. They are characterized by good rigidity and excellent guidance, and are suitable for mass production.
③ Nut taps: Specifically designed for processing the internal threads of nuts, they may vary in design to accommodate the special shapes and processing requirements of nuts.
④ Extrusion tap: It is used for plastic deformation processing of metal threads without generating chips. It is suitable for materials with good ductility such as aluminum alloys, copper parts and low-carbon steels, etc. It can be used for blind holes or through holes. The threaded holes processed have high tensile and shear strength as well as good surface roughness.
⑤ Straight groove tap: Its characteristic is that the number of cutting edges is equal to the number of grooves multiplied by the number of cutting cone teeth. It is suitable for through-hole processing. The chips can be easily discharged forward and are not prone to entangling. It has a high flexural strength and good cutting performance.
⑥ Helical groove tap: It features helical grooves and can be processed to the bottom of blind holes without leaving chips. It has excellent cutting performance and can be used for both through holes and blind holes. The chips are curled and are suitable for materials with good ductility.
⑦ Edge Angle tap: It features an edge Angle design that enables chips to be discharged downward or forward, making it suitable for specific materials and processing conditions.
⑧ Metric coarse thread taps, metric fine thread taps, pipe thread taps, etc. : These are taps designed according to different standards and thread types, used for processing corresponding types of threads.
In conclusion, taps come in various types and are suitable for different processing requirements and material properties. When choosing taps, the most suitable type should be determined based on specific processing requirements and the material of the workpiece.
