A Tapping Machine is used to create internal threads (tapping) in pre-drilled holes of various materials like metal, plastic, or wood. It is an essential tool in the manufacturing and engineering industries for creating threaded holes to fit screws, bolts, or fasteners.

Types of Tapping Machines:

1. Manual Tapping Machine: Operated by hand for small-scale or low-volume work.
2. Semi-Automatic Tapping Machine: Requires manual feeding, but the tapping process is automated.
3. Automatic Tapping Machine: Fully automated for high-volume production, with automatic feeding, tapping, and removal.
4. CNC Tapping Machine: Computer-controlled for precise and repetitive threading operations.
5. Pneumatic Tapping Machine: Uses compressed air for quick and efficient tapping, often used for light to medium work.
6. Hydraulic Tapping Machine: Uses hydraulic power for heavy-duty tapping in tougher materials.
