This Mũi taro máy is specially developed for producing bicycle threads (FG) according to the DIN 79012 standard. Made from high-quality HSS-E material, it allows for precise cắt ren in common steels and metals. Its Form C design ensures a smooth cut in through and lỗ bít, making it a reliable tool for bicycle repair and manufacturing.
Q: What is special about an FG bicycle thread?
A: The FG thread has a flank angle of 60°, which it shares with many other bicycle standards. This can sometimes make correct identification of the thread standard difficult, as mix-ups can happen quickly.
Q: Why should I be particularly careful when working with FG threads?
A: Due to the similarity of flank angles with other standards, it is advisable to use the thread table very carefully. The manufacturer recommends never using force. Attempts to create a screw connection with force can damage the thread and lead to unsafe connections.
Q: What does the material designation HSS-E mean?
A: HSS-E (High Speed thép with Cobalt) is a high-performance alloyed high-speed thép. The addition of cobalt increases the tool's hardness, temperature resistance, and wear resistance. This leads to a significantly longer tool life, especially when machining materials that are difficult to cut.
Q: What is a thread according to DIN 79012?
A: DIN 79012 is the standard for bicycle threads, which specifies the dimensions and tolerances for these specific threads. The designation FG 2 x 56 stands for the nominal size and pitch of the thread.
Q: Can I also use this tap for other thread standards?
A: This tap is specifically designed for producing FG 2 x 56 bicycle threads. Due to its specific dimensions and pitch, it is not suitable for other thread standards. Using it for unintended threads can lead to inaccurate results or damage to the workpiece.
