How to make tapping?
The work piece and tools must be placed neatly before tapping, The tap size and depth of the tapping machine meet the required size before starting the operation. Prevent slipping and not enough teeth.
Waste materials (such as iron slag powder) should be left during the tapping process, and there should be space or slot to facilitate the discharge of debris. Clean up at any time.the tapping machine often checks the work quality of the work piece.
The hole of the threaded bottom hole on the work piece is chamfer, and both ends of the threaded hole are chamfer. the position of the work piece clamp should be correct, so that the center line of the threaded hole can be placed horizontally or vertically, so that tapping can be easily judged whether the axis of the tap is perpendicular to the plane of the work piece.
At the beginning of tapping, try to straighten the tap, then press the tap and rotate the winch. When cutting in 1-2 circles, carefully check and correct the position of the tap. When the thread is cut into 3-4 circles, the position of the tap should be correct.
When replacing the latter tap in the process of tapping, the tapper should first enter the tapped thread and the tapped thread by hand, and then turn it with a winch when it can not be re-spun.
