Mũi taro máy JIS B-4430 Form B HSS-E - NPT 2" x 11.5

Mũi taro máy JIS B-4430 Form B HSS-E - NPT 2" x 11.5

This threading tool is used to produce or restore ren trong in tapered pipe thread systems. It is applied when controlled tool guidance and a consistent thread profile are required, for example in workshop production, maintenance, or repair tasks. The tool cuts the thread profile directly into a prepared core hole, enabling a functional connection in pressure carrying pipe systems.

The designation NPT refers to a tapered pipe thread that seals through flank interference and is typically used in fluid and pneumatic applications. The standard JIS B-4430 defines requirements and geometries for taps within the Japanese standard system and ensures that the tool geometry and thread profile correspond to the specified thread standard.

Tap for tapered ren trong in the NPT system, Form B according to JIS B-4430, tool material HSS-E.

Ứng dụng

• Producing tapered ren trong in components for pipe connections.
• taro lại ren existing threads during maintenance or repair.
• Machining prepared core holes in workshop or assembly environments.
• Use in single part production, small batches, or service work.

Lưu ý Process: manual driving or assisted driving depending on your holder and machine configuration. Use: cắt ren, taro lại ren and làm sạch ren depending on the condition of the thread.

Các bước thực hiện

1. Check the thread designation in the product name and confirm it matches the intended application.
2. Prepare the core hole for the specified thread system and remove burrs from the hole edge.
3. Clamp the tap in a suitable holder or machine tool interface.
4. Align the tool carefully with the axis of the bore.
5. Apply suitable cutting fluid to the tool and the bore.
6. Rotate the tool with steady feed into the bore.
7. Pause briefly if resistance increases and then continue the cutting movement.
8. Reverse the tool completely out of the thread.
9. Clean the thread and verify the fit with a matching component or gauge.

Câu hỏi thường gặp (FAQ)

What is a Mũi taro máy used for?

A Mũi taro máy produces ren trong in prepared holes. It is commonly used in machine holders but can also be guided manually with an appropriate holder.

What does the thread designation NPT mean?

NPT refers to a tapered pipe thread. Sealing occurs through flank interference between the internal and ren ngoài and it is commonly used in piping systems for liquids and gases.

What does the standard JIS B-4430 define?

The standard specifies geometry and requirements for taps within the Japanese standards system to ensure compatibility with the intended thread profile.

When should you re tap a thread?

taro lại ren is useful when an existing thread is contaminated, slightly damaged, or affected by corrosion. The tap restores the original thread form.

Why is cutting fluid important during cắt ren?

Cutting fluid reduces friction and heat at the cutting edge and helps transport chips out of the flutes of the tool.

How do you avoid starting a thread at an angle?

Align the tool carefully with the bore axis and begin the cutting process with controlled torque. A stable holder improves guidance.
