We started our activities in 1955 as a local supplier of threaded bars for the bar-turning industry.And today we are the leading supplier of screw-drives for transmission industry. One of the reasons explaining our leading position on the market is our will to focus on our mainactivity : cold-formed threading. We also owe this position to our customersʼ confidence and to thecommitment of our staff. Thus we use our knowledge, know-how and energy for the benefit of thedevelopment of one product: threaded spindles !With an extensive range of tools, we actually offer a very broad variety of rolled threads on themarket, such as : trapezoidal, ball-screw, worm, metric, UN, and special profile, multi-starts, right-hand, left-hand and knurling.We possess the most powerful machine in the world for cold-formed threading which allows usto offer a wide range from Ø 1.5mm up to Ø 430mm, and pitches from 0.35mm up to 24mm (orModule 7), in lengths beyond 12m.Our possibilities in the field of machining in relation with our production of threaded bars allow us toensure the optimal manufacture of machined threaded spindles. Of course, we manufacture nutsaccording to your drawings and specifications.
OUR PROCESS
Cold-formed threading, more commonly called rolling, implies the cold forming of a metal bar bypressing during rotation with tools called dies, in order to obtain a thread or a knurling.Thanks to this performing process, we manufacture amongst others metric, trapezoidal threads, ballscrews and worms, using different materials such as current and special steels, stainless steel,brass and numerous alloys.
ECONOMIC EFFICIENCY
The process of rolling allows a high production and an important saving in material as thediameter used is below nominal and unlike cutting it has no chips, thus no material loss.
Improvement of the mechanical properties :
- Gain reaching 30% on hardness and 12% onbreaking strength, in fact the fibers of the materialare formed but not cut as in case of cutting.
The roller finishing on the surface considerably increases the life time of the screw or of the nut,improves fatigue strength and eliminates the starting points of fracture
