JZ7G 130Seven 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.

Represent Steel: Stainless Steel.

Round Bar Condition: Based on DIN-EN 10060:2003 Standard.

4,material property: Tensile Strength; Tensile Strength Limit :≤1000Mpa, Hardness≤350HB.

5,Temperature when straightening:Room Temperature.

6,Raw Material:

input curvature：≤8mm/m,input curvature in full 7m length ≤20mm.Two ends chamfered, no hook end.

Diameter tolerance:≤d-2-GB/T 702

Roundness:50% of diameter tolerance

7,Output straightness: ≤1mm/m( this should be the measured valve minus ovality , when near limit diameter of the range or two ends of the bar ,the straightness is ≤1.8mm/m), Straightness measurement method: platform feeler method.

8,Process Rate: 5-20m/min Bars with high strength, high hardness, large or small diameter, large roundness, and large original straightness must be slowed down.

Note: Round steel cannot roll on the rack and requires manual feeding
