Thread Rolling Machine

The thread rolling machine uses eccentric rolling precision small screws, such as needle screws, electronic screws, straight/diagonal patterns and other precision parts.

Thread Rolling Machine

Advantages of the thread rolling machine:

  • High efficiency, high precision
  • Rugged construction
  • Extremely simple operation
  • Wide range of uses

The two roller rolling screws in the thread rolling machine replace the cutting method to form a metal structure by an effective cooling and casting process.

The benefits of this process not only provide a quicker and more precise amount of business screw, but also greater stretch, shear and durability than the rolling screws produced by the cutting method.

Thread rolling machine classification

The thread rolling machine is a multifunctional cold rolling forming machine.

The thread rolling machine can perform thread, straight and twill rolling on the workpiece in the cold state; traverse, helical and oblique spline gear rolling; straightening, reducing diameter, rolling and various forming rolling.

The machine has a safe and reliable electro-hydraulic execution and control system that allows each duty cycle to be selected in manual, semi-automatic and automatic modes.

The rolling cold rolling process is an advanced non-cutting process that effectively improves the intrinsic and surface quality of the workpiece.

The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece.

It is an ideal process for high efficiency, energy saving and low consumption.

Thread rolling machines are divided into:

  • Two-axis eccentric type
  • Two-axis rolling type
  • Two-axis hydraulic type
  • Two-axis hydraulic rolling type
  • Triaxial cam type type
  • Three-axis hydraulic type
  • Triaxial hydraulic rolling type

When the thread is machined, the roller molds are respectively mounted on the rotating shafts of the two-axis and three-axis machines, and the extrusion threads are formed.

Roll different threads to replace different sizes of roller die.

It can process triangular thread, ladder pattern, straight line, net pattern, twill and so on.

Thread rolling machine advantages

The product is stable in size and high in precision.

For the mass production of precision screws, there is a fixed type thread rolling machine and rolling type thread rolling machine.

The fixed type can be equipped with a vibrating plate if the size allows, can realize fully automation.

Rolling type is suitable for machining workpieces with large lengths.

The three-axis machine is mainly for the processing of hollow pipe threads.

It’s specially designed for tube parts.

With the equilateral triangle support, the roundness, high precision, concentricity and verticality of the workpiece are determined.

It is a must for the fastener industry.
