    JY Series of straightening machine can realized precise straightening and polishing on the after peeling or grinding metal bar surface utilizing the special curves and angles between the top and bottom two rollers. It can be used in black bar material straightening as well.
There are 3 types of structure in straightening machine, two beam four column structure, prestressed structure and frame structure.The straightness can be up to 0.15——0.4mm/m , and the roughness Ra<1μm after straightening.

straightening roller:

For two-rolls straightening machine, the bending moment of raw material is realized by concave roll. Another advantage is that the angle between rolls angle and rod axis is small, whiche is 15^°. So the screw pitch of envelop line is shorter, and its straightness accuracy is higher.

Application: It could be used for bright bar , and black bar with suitable bending and surface hardness .Its straightening speed is slower than multi-rolls straightener, but its straightness accuracy is higher ,and its cost is lower.

Loader→Uncoil machine→Centerless lathe→Cutting machine→Charging basket

    We have exported to the following countries: Europe and the United States, Russia, Belarus, Pakistan, South Korea, North Korea, India, Vietnam, Taiwan, South Africa, Brazil, Thailand, etc.

    We have rich experience in export packaging with professional packaging and professional packing staff. Multilayer packaging is adopted with critical area wrapped with moisture proof and shock proof film, plywood box, or wood box and tray. Multiple reinforcement measures is applied to ensure the solid fixation of equipment on packing box and tray, and the stability of equipment in the container.

• The first layer: wrapped with foam film and stretch film for the special components for the sake of avoiding moisture.
• Second layer: adopting small square plywood block and strapping belt to fix the machine inside the plywood box
  
• Third layer: the machine itself has screw fixing holes, so it can be tightly fixed on the bottom of the plywood box through screw and nut.
• Fourth layer: inside the container, the gap between machine parts are filled with compact layout to avoid shaking. At the same time, reinforcing between the bottom of the container and plywood boxes once again, furthermore using hanging steel wire protection.
