A thread rolling machine is a mechanical processing equipment that applies pressure to the surface of a workpiece through a rolling mold, causing it to undergo plastic deformation and produce threads. Ronen® is a fastener machinery manufacturer of China, and our engineers will provide you with the most professional advice.
The thread rolling machine produced by Ronen® is easy to operate and can be used to machine threads on metal parts. Suitable for bolts, rods and small shafts, without the need for complicated settings. Just load the materials, set the thread size, and the machine will start running until it stops. This machine is a device specifically used for machining threads on parts such as bolts and screws. Its working principle is to use two threaded rollers to press the surface of the metal workpiece, causing the metal to deform and form threads.

The manufacturing industry of standard parts cannot do without thread rolling machines. Producing a large quantity of bolts, screws and studs all require the processing of threads. This machine is the core equipment. For example, when manufacturing M8 hexagonal bolts, first make the shaft and head of the bolt, then place it on the machine, which can roll out the full thread. It can ensure that each thread has the same pitch and tooth profile.
The features of our machine are quite obvious. It is a cold processing machine. The rollers can be replaced. To process different specifications of threads, just replace the corresponding type of rollers. The noise of the machine is not too loud. It runs smoothly and has little vibration. The processed threads have high precision, with errors controlled within a very small range. They fit the nuts very smoothly and there will be no looseness or inability to turn.
The thread rolling machine can form threads without cutting metal. It uses hardened steel molds with reverse thread patterns. The machine presses these molds onto a smooth cylindrical workpiece (called a blank) under extremely high pressure. The molds force the metal on the blank to flow and undergo plastic deformation, transforming it into a threaded shape. This creates an external thread through cold forming.
The selling points of the thread rolling machine are very prominent. Firstly, the processing speed is very fast. A single workpiece can be rolled into a threaded shape in just a few seconds, which is much faster than cutting processing and is suitable for mass production. Secondly, the quality of the threads is excellent. The threads rolled out have a smooth surface and high strength because the metal fibers are not cut, making them more durable than those cut by cutting. Moreover, it saves materials. There is no need to cut off the excess metal, which can reduce waste. The operation is also not complicated. Just adjust the spacing and speed of the rollers, and place the workpiece inside.
