Hard materials, such as pre-hardened steel, carbide, high-speed tool steel, etc., pose great wear challenges to machining tools due to their high hardness properties.
- Reduce the risk of tool wear and breakage
Tapping: When tapping, the cutting load of the entire thread shape is concentrated on a small number of cutting edges, especially in hard materials, which increases the risk of tool wear and breakage.
Milling: In contrast, milling tools have more cutting edges distributed during machining, which means that the cutting load is distributed, thereby reducing the wear rate of each cutting edge and reducing the risk of tool breakage.
- Improve processing efficiency and control
Tapping: When processing hard materials, tapping requires a slower feed speed and more interruption time to facilitate the removal of chips and the entry of coolant, which reduces the processing efficiency.
Milling teeth: Milling teeth allow processing at higher feed rates, and due to its open processing environment, chip removal and coolant application are more effective, which is crucial for improving hard material processing efficiency and controlling processing temperature. .
- Processing quality and precision
Tapping: Hard materials may deform due to high cutting forces during tapping, affecting thread accuracy and quality.
Milling teeth: Milling teeth provide better cutting force control and can more accurately control the size and shape of threads, which is especially important for applications requiring high precision.
- Flexibility and adaptability
Tapping: Tapping in hard materials may be limited by machine tool capabilities and tool design.
Thread milling: Thread milling is more flexible and can be performed on a standard CNC milling machine, and can be easily adjusted to suit different thread specifications and design requirements.
