3 Roll Thread Rollers

The use of 3 rolls as opposed to 2, means higher penetration and therefore increased production rates. The three forces at 120° ensure stability during rolling & maximum precision of the finished workpiece.

The 3RP series hydraulic thread and profile rolling machines are equipped with 3 rolling spindles with 3 moving heads.

The machines can be controlled by means of the PLC or CNC and have rolling pressures ranging from 100 to 1,500  kN. They have been developed to roll any type of thread and profile on tubes or solid material from a minimum diameter of 6.35 mm to a maximum diameter of 300 mm.

The 3RP series machines are particularly beneficial for plunge or through feed rolling operations on both hollow and solid components with large diameters.
