A tapping machine is a machine used for cutting threads on the inside of a hole, by means of a cutter with multiple teeth that produces spiral grooves on the work piece. Tapping machines come in a wide variety of sizes and styles, from small hand-held models to large floor-standing models.
Major Types of Tapping Machine:
There are two main types of tapping machines: those that use a rotating tap and those that use an oscillating tap.
Rotary tapping machines: Rotary tapping machines are the most common type, and they can be operated manually or automatically.
Oscillating tapping machines: Oscillating tapping machines are less common, but they offer some advantages over rotary machines, such as higher accuracy and faster speeds. No matter what type of tapping machine you use, it is important to select the correct tooling and accessories to ensure optimal performance and safety.
Portable tapping machine: Portable tapping machines are small and lightweight, making them easy to transport from one job site to another. They are also relatively inexpensive, making them a good choice for budget-conscious consumers.
Floor-mounted tapping machine: Floor-mounted tapping machines are larger and more expensive than portable tapping machines, but they offer greater durability and power.
CNC tapping machines: CNC tapping machines are the most technologically advanced type of tapping machine. CNC tapping machines are computer-controlled, making them extremely precise and efficient.
Mechanism of Tapping Machine:
Tapping machines are used to create internal threads in parts that have been previously drilled.
First step: The first step is to select the correct size and type of tap for the application. Once the tap has been selected, it is mounted in the tapping machine and aligned with the drilled hole.
Second step: The next step is to set the correct speed and feed rate for the tap. The speed should be slow enough to prevent breakage, but fast enough to avoid excessive wear on the tap. The feed rate determines how much force is applied to the tap as it turns.
How to Use Tapping Machine?
Too much force can break the tap, but too little can cause it to overheat and wear out prematurely. Once the speed and feed have been set, the tapping machine can begin its work. It will automatically advance the tap into the hole and then back out again when the job is complete. Tapping machines are an essential tool for any machinist, and with a little practice, they can be operated with precision and accuracy.
Advantages of Tapping Machine:
The advantage of using a tapping machine instead of another type of thread-cutting operation, such as hand tapping, is that it produces a much superior thread, with very little tolerance for error.
Tapping machines are faster and more efficient than hand operations, and they can be used on a variety of materials, including metals, plastics, and even wood.
Conclusion:
Tapping machine is a machine used for cutting threads on the inside of a hole, by means of a cutter with multiple teeth that produces spiral grooves on the work piece. Tapping machines come in a wide variety of sizes and styles, from small hand-held models to large floor-standing models.
