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.

Advantages compared with the general lathe

1. The over-long metal bars or the wire rods can also be processed.

2. The precessing speed: 1~12m/min which is several times faster than the general lathe.

3. High precision. The diameter tolerance  ≤IT9 while the surface roughness ≤6.3μm after peeling.

   The surface roughness can be less than 0.8μm if our straightening machines are used afterward.

Applications

1. Ferrous metals:

Stainless steel, bearing steel, spring steel, tool steel, structural steel, alloy steel, free-cutting steel, air valve steel, gear steel, others;

2. Nonferrous metals:

Copper alloy, titanium alloy, magnesium alloy, aluminum alloy, etc. Widespread in preparation link in manufacturing of slender axles, hydraulic/pneumatic elements, bearings, springs, auto parts, textile machinery, processing of cold forging materials, instruments, steel pipes, cutters, engineering machinery, sports equipment and other machiner.

3.Widely applied to industries of  copper, titanium, aluminum, magnesium, petroleum, power and bridge

(e.g. piston rod, optical axis, bolt, spring, rack, rod thread, stainless steel rod, copper rod, titanium rod, aluminum rod, magnesium rod, bearing ring, draglink, roller shaft, pin, polishing rod, screw, core rod, oil drill pipe, tightwire, pipe blank
