Description:
This equipment is a LJ220 type 7-roller precision straightening machine, designed for straightening ordinary steel bars with diameters ranging from Ø50mm to Ø170mm, includes a set of LJ 220 vertical seven- roller bar straightening machine. (including loading roller and unloading roller )
 
Straightness:
≤ 1 mm/m. It is the data obtained by subtracting the ovality deviation from the measured value. The straightness of the two ends of the bar and the larger or smaller diameter is larger.
 
Straightening speed:
about 0-20 m/min. The designed maximum speed is 20 m/ min. The speed should be reduced for bars with high strength, high hardness, large or small diameter, large roundness, and large original straightness.
 
Our service: 1. Free quality guarantee period for 12 months, except for wearing parts. 2. Free provide long-term technical support 3. Free train buyer's operator in seller's factory 4. Fast response service within 24 hours 5.Our engineers can offer overseas service, including guiding installation, commissioning, training, etc, if our customer needs.
