1.Especially design for pipe parts, use triangle as support, to guarantee the true roundness, concentricity and verticality of products during rolling
2.In feed & Thru feed can be realized in one machine
3.Spindle speed is controlled & adjustable by inverter
4.Three hydraulic cylinders feed at the same time
5.Transmission gear is grinding after heat treatment
6.Mainly for making thread on scaffold tubes
7.High precision, stability & durability
8.CE Certificates

This is one heavy duty thread rolling machine with three rollers , main motor: 11KW, hydraulic motor: 5.5KW. The Max. Rolling pressure is 40T. Can be used to make triangular thread, trapezoidal thread, knurling, widely used to make external thread or knurling on hollow tube, such as scaffolding thread, construction screw, etc.
In feed and through feed mode can be realized on the same machine. It is easy to change thread rolling dies, and adjust angle of main shafts.
Since there are 3 pcs thread rollers on the machine, so an equilateral triangle will be formed after adjusting the thread, the pressure in three different directions on hollow tube product is very uniform, so the hollow product can maintain good concentricity. Whether it is a seamless pipe or a welded pipe, the principle is the same.
Rotation speed of the machine can be adjusted by changing gears in the gearbox, so different speed can be used according to different products in real production.
With the development of science and technology, the demand for automatic machinery in various factories is getting higher and higher, same as for thread rolling machine. We have our own professional R&D team, which can design many different customized automatic feeder according to exact product from customers. The automatic thread rolling machine can help lots of factories to save cost, to produce safely.
