Tapping is a mechanical process used in manufacturing and engineering to create threaded holes in materials such as metal, plastic, or wood. Threads are essential for securing bolts, screws and other fasteners, making tapping a crucial method for assembling components and structures in various industries.
What is tapping?
The process of tapping involves the use of a tool called a tap. The tap is a cutting tool with helical grooves that match the thread profile needed for the specific application. There are various types of taps including spiral point taps and spiral flute taps, each designed for specific purposes and materials.
The tapping process can be performed manually using hand taps, or automatically using machines like drill presses or form-tapping machines. Form tapping is said to be a quicker and more modern process than other cutting taps
The steps involved in tapping are as follows:
Drilling: Before tapping, a hole is drilled in the workpiece to the correct diameter.
Prepping: The tap is aligned with the hole to ensure it is correctly positioned.
Tapping: The tap is inserted into the hole and rotated to cut threads into the material.
Backing off: After a few rotations, the tap is reversed slightly to break the chips and reduce the risk of the tap breaking.
How is tapping used in industry?
Tapping is used in various industries including automotive, aerospace, construction and electronics.
Tapping is preferred when compared to other methods like threading with a die or using thread-forming screws because it offers higher precision, better thread quality and greater versatility in terms of material compatibility and thread size. Additionally, tapping can be performed on both through-holes and blind holes, expanding its range of applications.
