Understanding Tapping - A Key Machining Process

Tapping, also known as threading, is a method for machining internal threads on workpieces. Here are some introductions about tapping:

**I. Basic concept**

1. Tapping is also called threading and is a method for machining internal threads on workpieces.

**II. Machining process**

1. Generally, a tap is used as a tool.

2. Rotate the tap and gradually screw it into the pre-drilled hole of the workpiece to form an internal thread.

**III. Application fields**

1. Widely used in the machinery manufacturing industry for connecting various mechanical parts.

2. In the automotive industry, it is used for assembling and fixing automotive parts.

3. It also has important applications in the aerospace field to ensure the stable connection of aircraft structures.

4. In the electronics industry, it is used for assembling electronic devices.

**IV. Types of tapping**

1. Manual tapping: Operate with a hand tap and is suitable for machining internal threads in small batches and with low precision requirements.

2. Mechanical tapping: Operate with an electric or pneumatic tapping machine and is suitable for machining internal threads in large quantities and with high precision requirements.
