In the field of mechanical machining, taps are indispensable tools for creating internal threads. However, tap breakage is a common issue. This article will explore the reasons for tap breakage and provide practical removal techniques, as well as best practices for preventing tap breakage.
Taps, as tools used in mechanical machining to create internal threads, are simple in design but prone to damage during operation. This article will guide you on how to safely and effectively remove broken taps and provide preventive measures to ensure a smooth machining process.
Reasons for Tap Breakage: Tap breakage can be caused by a variety of factors, including:
- Poor tap quality
- Improper tap selection
- Incompatibility with the raw material
- Excessive wear and tear of the tap
- Axial synchronization error
- Difficult chip breaking and removal
- The bottom hole diameter is too small
- Poor quality of cutting fluid and lubricating oil
- Unreasonable cutting speed and feed rate
Methods for Removing Broken Taps: Faced with a broken tap, here are some effective removal methods:
- Using tap extractors
- Manual removal
- Using a pneumatic drill
- Using a chisel
- Using EDM machines
- Drilling to make another hole
- Using a grinder
- Using a lubricating agent
- Using chemicals
- Welding to remove broken taps
Best Practices for Preventing Tap Breakage: To reduce the risk of tap breakage, here are some best practices:
- Ensure the tap is aligned with the pilot hole
- Do not force rotation
- Maintain even force when tapping
- Use the appropriate size of spanner for the tap
- Position the tapping length on the tapping tool
- Carefully remove the tap
Conclusion: Tap breakage is a common issue in mechanical machining, but by understanding its causes and mastering effective removal techniques, its impact on production can be greatly reduced. Additionally, taking preventive measures and choosing professional CNC machining services, such as Unofactory, can ensure precision and efficiency in the machining process.
