What should be done to prevent vertic...
What should be done when vertical streaks (stop marks) are formed in tapered threads for pipes? When tapping, vertical streaks known as "stop marks" are ine... 詳細表示
What should be done if the machine st...
Tapered pipe tapping tends to require 2 to 3 times more torque than parallel thread tapping of the same size. This can lead to machine stops due to overload... 詳細表示
What is an Increasing Diameter Tap?
The number varies depending on the material and shape to be processed, but it is a set of multiple taps (the diameter of the screw gradually increases), and ... 詳細表示

How to suppress burrs at the hole en...
In forming tap processing, the material is displaced by plastic deformation, resulting in a raised shape (burr) at the hole entrance. To suppress these burr... 詳細表示
The cone-shaped part of the tap tip is called " external center ". This part is attached during the manufacture of taps and is not used during threading. ... 詳細表示
