Z28-40 Thread rolling machine
Mainly used for all kinds of external thread, including the common thread, trapezoidal thread and modulus thread. It also can do the rolling process, forming, slidabrading, knurling etc..
Apply for all kinds of carbon steel, alloy steel and non-ferrous metals, the elongation is more than 10%, the compressive strength is less than 100 KGF/mm².
Roller Threading Machine Main advantages:
1. It can make the thread form of good quality. And it It has the high precision.
2. It can be used to process scerw and rebar. The rebar processed by the machine has the good overall mechanical. It can make the tensile strength increased by 20%-30%, the fatigue strength increased by 40%-60%, corrosion resistance increased by 50%-200%. Mechanical properties of rebar connector reached and more than international standards.
3. It works safe and reliable. It can works all day long, and can save steel and energy.
4. It adopt innovative design and advanced technology, also it has the high precision and easy to operate.

Yushi thread rolling machine advantages compared with other supplier
The sliding base plate is thickened, with the thickness increased by about 40% compared to the original, making it more stable and durable. The top part is made of ductile iron casting. The sliding track uses tapered strips and a dovetail structure, making the slide rail more stable and durable during operation.
This tool uses a worm gear to adjust the stroke, which can achieve fine adjustment of the thread depth during workpiece processing. The handwheel only adjusts 0.2mm with one full rotation, while the original one adjusted 3-6mm with one rotation, a difference of 15-30 times in adjustment accuracy. The adjustment of the mold distance is very rough, and if the thread depth is slightly different, it is difficult to adjust. Either it is adjusted too deep and the material bounces up, or it is adjusted too shallow and it is difficult to tighten the nut.
The original 39mm diameter return rod with spring was replaced with an 80mm diameter double-acting hydraulic cylinder piston rod. The original rod was prone to breakage when performing heavy lifting or prolonged tasks, posing a safety hazard if someone was standing near the machine and could be injured. The improved model eliminates this issue of return rod breakage.
The hydraulic structure is bidirectional hydraulic, with high pressure for forward movement and low pressure for reverse movement during operation. Both forward and reverse movements are hydraulically controlled, achieving separation of high and low pressure, protecting the equipment, and reducing oil temperature. The hydraulic system is the same as that of the Z28-200, Z28-260, and Z28-280 large thread rolling machines, making it more stable and durable.
