Steel Rod Necking Machine

The steel rod necking machine is used to reduce the partial steel rod diameter by cold pressing technology. The compressed parts will be high density and high strength. With the diameter reducing process in advance, the final diameters of compressed parts after thread rolling can be keep same to the other part of steel rod. Compared to normal cutting lathe, the steel bar necking machine can increase the tensile strength and save the material consumption.

    2. Two-Die Thread Rolling MachineThe bar or rod thread rolling machine forms a roll from the straight thread, screw thread, and inclined thread on a solid bar or solid rod. The machine may be customized to handle nonstandard screw thread. The ideal calibration for the bar or rod diameter ranges between 5mm to 100mm while the screw pitch ranges from 0.5mm to 8mm.
