Choosing the Right Thread Rolling Machine Manufacturer
Thread rolling is a metal forming process used to create threads on round bars, rods and tubes.thread rolling machine manufacturer It is used in aerospace, defense, and other demanding applications requiring challenging high-strength steels and exotic materials. When done correctly, thread rolling provides excellent dimensional accuracy, precision and strength on long production runs. In order to get the most out of this process, it is important to choose the right machine for your application. There are many factors to consider, including material compatibility and production volume.
Flat Die Type
The most common type of thread rolling machine consists of two flat dies, one stationary and the other reciprocating.thread rolling machine manufacturer The surface of these dies contains ridges that incline at an angle equal to the helix angle of the thread being formed. When the dies are properly aligned, they can form threads that are a perfect match to those on the rolled stock.
These machines can be operated in either the in-feed or thru-feed manner.thread rolling machine manufacturer In-feed thread rolling is the most popular method of threading, and is used in most industrial applications. However, it is not suitable for use on parts that are too long to be rolled in a single pass through the dies. Thru-feed threading, on the other hand, is a two-step process that can be used to produce very long thread length dimensions. This is the preferred method for aerospace manufacturing and other demanding applications that require accurate, strong and consistent threads over a longer distance of the part.
To ensure a high level of quality and consistency, the ridges on the dies must be made to an exacting standard. The material must also have a certain degree of hardness and ductility in order to be rollable. If the dies are not correctly matched, or the blank diameter is too large, the threaded end may be rough and unstable. A poor blank diameter can also cause the formation of wavy or uneven crests on the thread.
Regardless of the type of thread rolling machine used, it is essential to have good control over all variables involved in the operation of the machine. Failure to do so will result in defective or unsatisfactory threads. These defects can be caused by several different factors, including improper or uneven feed of the work, mismatched dies and rollers, incorrect lubrication, poor roller surface, misaligned feeding, and slow rolling speed.
Thread rolling is a fast, economical, versatile and accurate machining technique that can be used on both small and large diameter parts. This method can be used to produce a wide range of threads with varying pitches and angles, making it an ideal choice for many applications in the manufacturing industry. Threads produced with this process have a lower coefficient of friction than those made by cutting, and therefore are easier to tighten or loosen. This is especially true when the threads are used in high-strength, low-friction applications such as aerospace components and automotive bolts and screws.
