This machine is a VFD-type Steel Bar Straightening & Cutting Machine specially for 6.0–16 mm plain round bars. Equipped with multi-wheel precision straightening structure and 3 sets of synchronized powered feeding rollers, it realizes continuous processing including wire pay-off, rough straightening, precision straightening and hydraulic fixed-length cutting in one single pass. Fitted with Inovance VFD control system, separate driving motors are configured for straightening, feeding and cutting to ensure stable adjustable running speed. Its cutting length ranges from 50 mm to 2500 mm with customizable extended length, cutting tolerance reaches ±0.1 mm and finished bar straightness is controlled within ≤0.15 mm/m. Key configurations include GB-standard UCP214 pillow block bearings, JZQ250 reducer and a straightening drum with 7 wear-resistant straightening inserts inside. A cover-open emergency stop safety device is equipped, and cutting blades are available for custom production per client specifications. With robust compact layout and easy operation, it is widely used for precision blanking of round steel in construction stirrup, wire mesh and hardware fastener manufacturing industries.
