LMT Fette Offers EVOline Thread Rolling

July 9, 2014
Rolled threads guarantee maximum strength and resilience in the most demanding situations. LMT Fette has been developing rolling systems for chipless thread forming for over 60 years. By utilizing 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 very 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 house and bridge building or sucker rods for the oil and gas industry, threads are used in practically every sector. Their job is always the same: 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 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 on 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 chipless production of external threads,” explained Stefan Möller, product manager rolling systems at LMT Tools. “This is our answer 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. That is why we included these requirements in the specifications for the EVOline from the very start and carried out intensive tests in these areas during practical field trials at four different plants.”
