JBO rolling dies to improve screw strength and surface roughness

The JBO screw rolling die is an efficient tool to instantly shape small diameter screws. Without having burrs and cracks like in cutting processing, it improves screw strength and surface roughness. Because it produces by rolling at the center of a 3 point roll, stable molding can be done with long screws. Due to single-shot processing by pitch feed, cycle time can be shortened.
