Threading & rolling special screws
Threading by chip removal
What is the comb-threading process ?
Screw threading is a technique for cutting metal in order to obtain a thread.
The advantages of threading :
The machine thread LANDIS offers the greatest flexibility in the shape of parts, in the variety of threads of ISO, UNF, UN, WHITWORTH, BSW … pitches and in dimensions from diameter 6 to diameter 150mm.
The diversity of our machine park and our stock of tooling allows us a very great reactivity.
VIAL can therefore offer you attractive costs on this type of service.
Machines VIAL: 16 threads per comb from 6 to 150 mm without length limitation
What does the rolling process consist of ?
Rolling is a technique of cold deformation of the material in order to make a thread.
The advantages of taxiing
• Material fibers are not broken or cut
• Removes break primers
• Save money
• Improves mechanical characteristics
• Improves fatigue strength and mechanical characteristics
• Gain on hardness and breaking strength
VIAL machine park : 6 Rollers diameter from 6 to 80 mm and about 200 sets of wheels.
