State-of-the-art thread forming from Evoline Rolling Heads

LMT Fette has been developing rolling systems for chipless thread forming for over 60 years now. By utilising numerous individual innovations and its wealth of experience with industrial applications, it has now created a completely new generation of rolling head: The EVOline sets the highest standards for efficiency, process reliability, precision and flexibility in thread rolling.

Whether it is fittings for pipe systems, connections for car bodies, jack screws for houses and bridge buildings or sucker rods for the oil and gas industry, threads are used in practically every sector. Their job always remains the same, which is firmly holding together what belongs together.

However, there are great differences in the production and quality of threads.
Thread rolling has established itself as an efficient alternative and replacement to thread cutting for three main reasons:

extremely short production times with the highest thread stability
constant dimensional accuracy
excellent surface quality

In addition, a thread rolling head can be used in a flexible way in almost all machining centers. As a result of its modular layout and a completely new tool design, the EVOline rolling head sets new performance standards for the chip-less production of external threads. This is LMT Fette's solution to the increased demands being made on thread rolling as a result of rising production volumes, new materials and integrated processing on tool machines. It is crucial here that tools offer process reliability, precision, flexibility and ease of operation.

Fine adjustment to accuracy of a hundredth of a millimeter
The exceptional features of the new rolling head include its simple but extremely accurate fine adjustment of thread diameter and the system's ease of assembly.

Adjustment of the rolling diameter is carried out using a spindle. The system is accurate to one hundredth of a millimeter and offers exceptionally high repeat accuracy of the effffective diameter. ThThe new
rolling head guarantees the repeatability of the thread diameter with the same setting within a range of +/- 0.01 millimeters. LMT Fette has applied for a patent for its new adjustment system.
