    The company is based on the manufacturing plant---Yantai Haige machine tools Co.,Ltd & Yantai Hangjian Refined Special Steel Equipment Co.,Ltd. whose area is more than 70000m2. There are one hundred and forty staffs working in the factory. The factory is mainly engaged in producing and selling bar peeling machines(centerless lathes), straightening machines, polishing machines(abrasive belt machines), auxiliary machines and other processing and finishing equipment for steel(bright steel) for more than ten years.

 from Outside the Factory

    Our company has strong R&D and production capacity. Equipped with specialized R&D center whose R&D capacity, software and hardware configuration, and the staff size all rank first in this field.  Keeping in step with the latest international technology, the R&D center develops the new equipment and upgrades the existing ones that provides a solid technical support and guarantee for our machines to keep technology leadership all the time.With advanced technology, high quality, high precision, high reliability, high efficiency,automatic line process and excellent after-sale service,our metal finishing equipment in full sets not only have been sold well to nearly thirty domestic provinces, cities, and autonomous regions, but also spread to Russia, Korea, India, Vietnam, North Korea, Pakistan, Taiwan, etc.

 from Inside the Factory

    Our company regards quality of products as the life. It has passed and strictly enforced the ISO9001 international quality system certification.Depending on strong software&hardware facilities and strict quality control, the company has passed the inspection and acceptance of the State Administration for Entry-Exit Inspection and Quarantine Bureau and won the centerless lathe " Export Quality License" as well as straightening machine " Export  Quality License".

Straightening machine:

    Series JY straightening machine is mainly used forprecision straightening for the metal bar after peelingor granding and pre-straightening  for the metal bar.

    The machine adopted special  curve between upper concave and the lower convex two straightening rolls to realize calendering and straightening at the same time,which greatly improved the working efficiency.  Series JY two-rolls Straightening Machine consists of two-beams and four-columns structure,prestressed structure and frame structure.

Characteristics

1,fast feeding and straightening speed,which can reach 10-30m/min.

2,with special carves ,it can straighten and calender materials at the same time.

3,highe precision.straighteness can be 0.15-0.4mm/m,surface roughness Ra≤0.8μm.

The most vital part of a straightener is the two

straightening rollers, which desigined by our qualified engineers.The up roller is concaveand the lower one is convex,which formed a special curve to press strongly onto thematerials to realize straightening,as well as straightening.

Main Machine

   The upper and lower body respectively

install a straightening roller,the upper roller is concave ,the lower roller is convex.

   According to the diameter and the material properties of the bar,respectively to adjust upper and lower straightening roller angle,electric lift part adjust the gap between the two straightening rolls,start the cooling lubrication system,driven by main motor,to complete calendering and straightening at the same time. Frequency conversion stepless speed,realtime display the gap between upper roll and lower roll.Guide sleeves are installed in the inlet and outlet.Its location can be adjusted,playing guide and support role.During processing,the bar can accurately enter and leace the straightening rolls.

Process Description

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

     Our machines has been used in the preparation procedure of the following mechanical equipments manufacturing,such as slender shaft, hydraulic pneumatic components, bearings, springs, auto parts, textile machinery, cold forging  material processing, instrumentation, steel pipe, cutting tools, engineering machinery, sports equipment etc.. They can also be widely used in copper, titanium, aluminum, magnesium industry, petroleum, electric power, Bridges and other industries, for example, piston rod, optical axis, bolt, spring, gear rack, toothed bar, stainless steel bars, copper bars, titanium bars, aluminum bars, magnesium bars, bearing ring, tiebar roller pin, pin , light bars, screw, mandrel, petroleum- drill pipe, steel cable, pipe billet, 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.

 

    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.
