Beck-Crespel know-how and productivity in cold thread-rolling are widely recognised. We have kept pioneering this process for 40 years.
When performed properly , thread-rolling improves surface condition and surface hardness, with direct impact against fatigue, corrosion and galling. Thread-rolling should always be perfomed after heat-treatments.
25 thread-rolling machines, including two 80t, and one 100t.
Diameters rolled from M6 (3/8") to M180 (7") including on high tensile material
Maximum material hardness : 140 kg/mm˛(200 ksi/sq.inch), even on diameters above 50mm. For instance we cold roll Inconel 718 in the aged condition.
In house design and manufacturing of thread-rolling dies. This is a key advantage for us. We benefit from cheap rolling dies for standard and special threads. Thanks to our R&D programme on tools, we often can thread-roll what others cannot.
