JZ7G 120Seven Roller Straightening Machine

The WXC series of center-less lathe and JY series of straightening machines are high -level new equipment with independent intellectual property rights on the basis of absorbing and digesting foreign advanced technology, making adventurous innovation, and research&development take into consideration of actual situation of domestic companies. Our technology reaches the domestic advanced level in reliability and quality while keeps a relatively lower price, with its efficiency more several times than the conventional process. Our products are suitable to process different kinds of metal material, for instance, black metal material such as structural steel, alloy steel, spring steel, bearing steel,tool steel, copper and copper alloy, aluminum and aluminum alloy, magnesium alloy, titanium and titanium alloy and other non-ferrous metal materials. WXC series of centerless lathe is high-efficient specialized lathe to make a rough or fine machining to the surface of bar material such as slender shaft and other bars. It is able to not only get rid of the imperfection on the bar surface , de-carburized layer, crack etc, but also to guarantee relatively high accuracy. It is especially suitable to process extra long bar and bar with large machining allowance.

Main Technical Parameter

1.Raw material: hot rolled bar

2. Specification: Φ50-φ115

3.Material:Carbon tool steel, carbon structural steel, alloy tool steel, alloy structural steel, spring steel, bearing steel, stainless steel, high speed tool steel,  and other special steel.

Representative material: tool steel.

4.Material property:yield strength:σS≤700Mpa
5. Temperature when straightening:room temperature when steel material, when Titanium alloy needs to be heated.

6. Input curvature:(8mm/m),input curvature in full length ≤30mm.Two ends chamfered, no hook end.
Diameter tolerance:≤d-2-GB/T 702

Roundness:≤50% of diameter tolerance

7.Output straightness: ≤1mm/m(Excluding the estimated maximum blind spots of 1.5 meters at each end, this should be the measured valve minus ovality , The straightness of the diameter of the bar is slightly decreased.(Note:Because there are steps or threads and thick piers at both ends of the pipe, the two ends cannot be straightened, so the blind areas at both ends are long.In addition, multiple lifting and reciprocating straightening will also affect the straightness of the middle section of the pipe, and will greatly reduce the work efficiency)

Straightness measurement method: platform feeler gauge method.

8.Process rate: 4-15m/min(the speed should be reduced when straighten the material with high hardness,strength,limit diameter,larger roundness,straightness)(If there are steps or threads and thick piers at both ends of the pipe, the through-type straightening cannot be completed, and it needs to be straightened back and forth between the two ends, so the working speed needs to be reduced)

9. Other Parameters:

9.1. Total power：180KW.

9.2. Voltage：3X380V±10%.

9.3. Frequency：50Hz±2%.

9.4. feed direction: From left to right.

9.5. Accuracy measurement:conventional.

9.6. air consumption：20m3/h (pressure：≥0.5MPa. )

9.7. Max.height above the ground：2.8m.
