    WXC Series Centerless Lathe(commonly known as peeling machine)is a new generation high-efficiency lathe machine which is specialized in processing of metal bar surface such as slender shaft. It can not only quickly remove defects on the surface of round steel such as decarburization layer and cracks, but also realize relatively high precision and roughness. It is especially suitable for processing of super long round steel bar, with working efficiency several times of the traditional processing technology.
    This machine is mainly applied in the production of bright material and bright steel bar, and in the field of machinery manufacturing, auto parts, bearing production, spring manufacturing, military enterprises, the production and processing of slender shaft, titanium bar, copper bar, aluminum bar, magnesium bar and other non-ferrous metal bar or tube, and in the field of other machinery equipment manufacturing for material preparation.

    WXC series of centerless lathe includes CNC type and semi - automatic type.Semi automatic type is operated both hydraulically and manually. For example, tool is adjusted manually, feeding and extracting are realized with hydraulic controlled clamping device, and auto material loading and unloading are finished with pneumatic and electric controlled device. Operated with ease, high in cost performance, this machine is quite suitable for small or medium enterprises which requires lower degree of automation.

    Advantages compared with ordinary lathe

1.When processing over-length bar,Centerless Lathe has incomparable advantages.Ordinary lathe is good at processing short bar.But there is great restriction for processing long shaft.In theory,Centerless Lathe can process the bar of infinite length.

2.Centerless Lathe is not only processing bar,also wire rod.Including from wire rod to wire rod and from wire rod to bar that ordinary lathe can't do it.

3.Processing speed 1-12m/min,the working efficiency of Centerless Lathe is dozens of times of the ordinary lathe.

4.High precision,after peeling,tolerance of diameter reach≤IT9,surface roughness Ra≤6.3μm.But after peeling,Ra≤0.8μm.

    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.

     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. 

    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".
