Getting the Most Out of Machining with Tapping: Definition, Processes & Types
Tapping is a machining process that involves cutting threads into a part to create a threaded hole. This process is used in a variety of industries, including automotive, aerospace, and medical. Tapping is used to create a threaded hole for fastening purposes and can be done with both manual and automated methods. In this article, we will discuss the definition, processes, and types of tapping to help you get the most out of your machining.
What is Tapping?
Tapping is the process of cutting internal or external threads into a piece of material. It is performed using a tap, which is a specialized cutting tool designed for this purpose. The tap cuts away material as it is rotated to create the desired thread shape and size. The resulting threaded hole can then be used to fasten or secure a part or component.
Tapping is used in many industries, including automotive, aerospace, and medical. It can be performed manually or with an automated process. Manual tapping requires a skilled operator to position the tap and rotate it at the correct speed and depth. Automated tapping uses a machine to control the tap’s speed and depth.
Types of Tapping
There are several different types of tapping, including hand tapping, machine tapping, and taper tapping. Hand tapping is the simplest type of tapping and is done by hand with a tap wrench and a tap. Machine tapping is done with a machine such as a drill press or milling machine that has a special attachment for tapping. Taper tapping is done with a special tap that has a tapered shank that helps guide the tap into the hole.
The type of tapping you use will depend on the application and the material you are tapping. For example, hand tapping is best suited for softer materials such as wood or plastic, while machine tapping is best for harder materials such as metals. Taper tapping is best for deep holes or holes with difficult angles.
Tapping Processes
The process of tapping involves several steps. First, the hole must be drilled to the appropriate size and depth. Next, the tap must be inserted into the hole and rotated at the correct speed and depth. The tap will then cut away material as it moves to create the desired thread profile. Finally, the tap must be removed from the hole.
When tapping, it is important to pay attention to the speed and depth of the tap. Too much speed or too deep a cut can cause the tap to break or the material to be damaged. It is also important to keep the tap lubricated to reduce friction and heat buildup.
Conclusion
Tapping is an essential machining process that is used in many industries. It is important to understand the definition, processes, and types of tapping to get the most out of your machining. Knowing the different types of tapping and the associated processes can help you choose the right one for your application and ensure a successful outcome.
