The Ronen® Iron Semi Automatic Nut Tapping Machine should not be used in combination with other materials, as specified by the manufacturer. Just manually insert the nut into the fixture, and it will automatically thread. Because it is faster than the fully manual threading process, it doesn't require constant supervision.
The Iron Semi Automatic Nut Tapping Machine is specifically designed for tapping internal threads in iron blanks. The delivery is done manually, while threading is done automatically. The operation process is very simple. The applicable thread specifications range from M4 to M18.
The features of the Nut Tapping Machine are that the fixture is suitable for iron nuts and the drill bit is durable. The fixture is made according to the hardness of iron nuts, which can firmly hold the iron material and prevent slipping during tapping, thus avoiding the distortion of the thread. The drill bit equipped is made of high-speed steel and is specifically designed for tapping iron.
The Nut Tapping Machine is a mechanically robust device specifically designed for cutting internal threads on nut blanks. The operator manually inserts the nut blank into the fixture and initiates the tapping process. This is usually done by pressing the two-hand start buttons or the foot pedal. Then, the machine automatically follows the tapping sequence.
This Iron Semi Automatic Nut Tapping Machine is mainly made of cast iron. The key reason why this material is preferred is its dual practical value - not only is it lightweight, which simplifies operation and installation, but it can also specifically suppress vibrations generated during the cutting process, reducing equipment wear and processing errors. The sturdy cast iron frame can make the spindle head and workbench stable, so that the tap and workpiece can be aligned very accurately during the entire operation.

The selling point of the Iron Semi Automatic Nut Tapping Machine is that it is specifically designed for iron nuts. It is less likely to break the tap during tapping and it is also cheaper. Iron is harder than copper and aluminum. When using an ordinary tapping machine to tap iron nuts, the tap is prone to getting damaged. The rotational speed and feed rate of its main shaft are adjusted according to the hardness of iron, allowing for slow tapping and reducing the wear of the tap. Moreover, it is semi-automatic and is more than half cheaper than fully automatic machines.
