Metal Tapping: Solving the Broken Tap Dilemma with Precision
In the CNC Metal Machining, tapping is a crucial process that determines the quality and functionality of countless metal parts. However, it's not without its challenges. One of the most frustrating issues that we often encounter is a broken tap lodged inside the CNC machining during the tapping operation. This seemingly small problem can have significant consequences, leading to production delays, increased costs, and potential damage to the parts.
At SGPROTO, we understand the importance of addressing this issue promptly and effectively. When a tap breaks during tapping, our team of highly skilled technicians’ springs into action. There are several ways to remove it:
1. Manual removal methods
a.Using needle-nose pliers or tweezers: If a part of the broken tap is exposed outside the workpiece and the exposed part is long enough, you can try to use needle-nose pliers or tweezers to pull it out.
b. Knocking method: When the broken part of the tap slightly protrudes from the surface of the part.
2. Removal methods using tools
a. Electrical discharge machining (EDM):, EDM is the most widely used. Electrical discharge machining uses the electro-erosion phenomenon during the pulsed spark discharge between the electrode and the workpiece to remove the excess metal. The advantage of this method is that the broken tap can be removed precisely and the damage to the workpiece is relatively small.
b. Using tap extractors
c. Drilling method
Once the broken tap is successfully removed. We meticulously prepare for a new tapping operation. This involves carefully inspecting the hole, ensuring that it is clean and free from any debris or residual material from the previous attempt. We will select the appropriate tap, considering factors such as the material of the parts, the desired thread pitch and size, and the specific requirements of the application.
Our commitment to quality and attention to detail ensures that the newly tapped hole meets the strictest industry standards. Whether it's a prototype or a samall production run,
SGPROTO to provide you with the professional solution you need.
