The Ronen® Automatic Prop Nut Threading Machine is specifically designed for spiral nuts, offering efficient and precise threading solutions for suppliers in the propeller and fastener manufacturing industries. It can precisely arrange the nuts and complete the thread cutting without the need for manual operation. Simply place the nuts in the feeder, and the machine will complete the processing automatically.
The Automatic Prop Nut Threading Machine is a device specifically designed for machining internal threads on nuts used on pillars. This machine is tailored to the dimensions and shapes of pillar nuts, including common cylindrical or hexagonal pillar nuts, and can precisely process them.
The Automatic Prop Nut Threading Machine is specifically designed for the threading of large propeller nuts and is suitable for marine applications.
This machine automatically cuts high-precision internal threads in pre-drilled holes in heavy nuts, easily handling the processing needs of propeller nuts primarily made of bronze or stainless steel. These nuts are often large and heavy, and the application of this equipment has completely transformed the traditional thread processing model, upgrading the previously manual, inefficient, and labor-intensive process to fully automated production.
This Machine employs a powerful hydraulic or mechanical clamping system. The custom jaws or dedicated fixtures can firmly grip the external geometry of the nut, preventing any movement or rotation during high-torque tapping operations. This is crucial for achieving precise and clean threads.
The Automatic Prop Nut Threading Machine is equipped with a high-capacity, high-pressure coolant system. This system can cover the taps and the workpiece, lubricate the cutting process, control the heat generated by the large amount of material cutting, and most importantly, sweep away the large amount of metal chips produced. The efficient chip removal can prevent the taps from getting clogged and ensure the quality of the threads.

The feature of the Automatic Prop Nut Threading Machine is its precise positioning. The holes for the stud nuts are usually centered. The machine's fixtures can firmly hold the raw material, and the tap won't get skewed during threading, ensuring that the thread is in the center position. There is an automatic chip-discharging groove. During threading, the iron chips that fall off will flow down by themselves and won't accumulate in the machine and get stuck.
