Hight Quality HSS M35 Thread Forming Machine Tap for Threading

Forming taps, also known as thread forming taps, are a type of tool used in machining for creating internal threads in materials without cutting. Instead of cutting away material to form threads, forming taps displace the material to create threads, resulting in stronger threads with improved surface finish and increased strength. Here's a detailed description of forming taps:

Features and Specifications:

1. Material:

   • Made from high-speed steel (HSS) or cobalt alloy (HSSCO) for increased durability and wear resistance.
   • Often coated with materials like titanium nitride (TiN) for enhanced performance and longer tool life.

2. Design:

   • Fluteless design which means they do not have the traditional cutting flutes.
   • Rounded or lobed thread profile that displaces the material to form threads.
   • Chamfered lead-in to ease the tap into the material and reduce torque.

3. Thread Forming:

   • Creates threads by material deformation rather than material removal.
   • Produces threads with a stronger and smoother finish.
   • Generates no chips, making it suitable for blind holes and reducing the risk of chip-related issues.

4. Thread Types:

   • Available in various thread standards, such as metric (M), unified national thread (UNC/UNF), and others.
   • Can produce different thread profiles depending on the application requirements.

5. Coatings:

   • Various coatings available, such as TiN (titanium nitride), TiCN (titanium carbonitride), or TiAlN (titanium aluminum nitride), to reduce friction, enhance wear resistance, and extend tool life.

Performance:

• Strength: Produces threads with superior tensile strength due to the work-hardening effect of material deformation.
• Surface Finish: Provides a smooth surface finish, reducing the need for additional finishing operations.
• Efficiency: Eliminates chip removal and handling, improving overall machining efficiency.

Applications:

• Blind Holes: Ideal for applications where chip removal is challenging, such as blind holes.
• High Production: Suitable for high-volume production environments due to their durability and long tool life.
• Varied Materials: Can be used on a wide range of materials, including aluminum, steel, stainless steel, and non-ferrous metals.
• Thread Strength: Preferred in applications where thread strength and precision are critical, such as in automotive, aerospace, and medical device manufacturing.

Advantages:

• No Chips: Eliminates the problem of chip management and disposal, especially important in blind holes.
• Stronger Threads: Produces threads with higher strength and better surface finish compared to cut threads.
• Longer Tool Life: Higher durability and resistance to wear, leading to a longer tool life and reduced tool changes.
• Consistent Quality: Provides consistent thread quality and accuracy, essential for precision machining.

Maintenance and Usage Tips:

• Proper Lubrication: Use appropriate lubrication to reduce friction and heat during tapping.
• Correct Speed and Feed: Follow recommended speed and feed rates to maximize tool life and thread quality.
• Material Suitability: Ensure the material being tapped is suitable for thread forming, as very hard or brittle materials may not deform properly.

Forming taps are an essential tool in precision machining, offering numerous benefits in terms of thread strength, surface finish, and overall efficiency. Their ability to create strong, precise threads without generating chips makes them ideal for a wide range of industrial applications.
