The Electric Nut Tapping Machine from Ronen®, a trusted manufacturer of workshop equipment, is specifically designed for quickly tapping screws. Just insert the nut and press the start button. The rest of the work will be handled by it. Many workshops purchase it when orders increase, trusting this manufacturer’s quality. It has a moderate size and can be placed on most workbenches.
The working process of the Electric Nut Tapping Machine is straightforward. The blank material is placed into the feeding machine, which will transport the blank to the designated position. Then, the tap rotates and drills into the hole of the blank to create threads. The processed nuts are pushed out.
The Electric Nut Tapping Machine is used to cut internal threads in the pre-drilled holes of nuts. It is equipped with a rotating tap (cutting tool) and precisely inserts it through the nut hole. This machine can automatically complete the tapping process for mass-producing nuts, forming the internal threads required for mating with bolts or screws. This replaces the slower and less consistent manual tapping process.
The machine uses the main shaft to firmly hold the tap. Commonly, a chuck or a special tap holder is used. The main shaft is driven by an electric motor, usually through gear transmission, to provide the torque and rotational speed (RPM) required for cutting the threads. When using a tap, ensure that it is precisely aligned with the hole on the nut (whether it is a pre-drilled hole or a drilled hole) to avoid misalignment that affects the processing effect.
The Electric Nut Tapping Machine can be set according to different types of nuts. For standard hexagonal nuts (through holes), the tap will completely cut the threads. For blind nuts (such as certain closed-end flange nuts), the machine will precisely control the tapping depth so that it stops before the threads reach the bottom. The depth control mechanism is crucial for blind hole tapping.

The main selling point of the Electric Nut Tapping Machine is its high efficiency, making it particularly suitable for mass production. The threads produced are of stable quality. The depth and precision of the threads on each nut are approximately the same. They fit well with the bolts, being neither too tight nor too loose. The operation is also very simple. Workers just need to pour the raw materials into the feeding hopper, set the parameters, and the machine will do the work by itself. There is no need to constantly monitor it, which can save a lot of manpower.
