In the rebar processing workflow, straightening and cutting are the most fundamental front-end procedures. The traditional method requires straightening rebars with a straightener first, then transporting them to a cutting machine for shearing. Double feeding not only wastes time but also easily causes length errors. The rebar straightening and cutting machine integrates straightening and cutting functions into one single unit. After coiled rebars are fed into the machine, they are automatically straightened via straightening rollers, then accurately cut to preset lengths by the cutting device in a fully automatic cycle. One rebar straightening and cutting machine can replace two separate machines. It saves floor space and labor costs, ensures consistent straightness precision and cutting length, making it an efficient choice for rebar processing plants and construction sites.
Advantages of YG Automatic Rebar Straightener and Cutter
YG automatic rebar straightener and cutter adopts exclusive designs in core components, including the feeding system, hydraulic unit, and length measuring system:
Four-wheel feeding inlet: Four sets of feeding rollers deliver synchronous feeding. Rebars are easy to insert with low resistance, running smoothly without deviation during feeding, which greatly improves feeding efficiency.
High-quality oil pump: Fast oil return speed, responsive hydraulic system, and long service life. It delivers crisp cutting action with flat, burr-free cuts.
Reinforced straightening frame: Integrally welded structure with high structural rigidity, resistant to deformation during high-speed operation and guarantees long-term stable straightening accuracy.
Upgraded solenoid valves: Effectively eliminate external leakage and minimize internal leakage for more precise hydraulic control and better consistency of cutting lengths.
Rapid hydraulic control system: Ultra-fast hydraulic response for instantaneous cutting movement, shortening idle waiting time for each cut.
Direct pressure length measuring system: Measuring wheels are made of Cr12MoV alloy tool steel with outstanding wear resistance, flexible adjustment, and precise data reading. Matched with patterned rollers, it maintains stable measuring accuracy without counting drift over long-term operation.
High-power 9kW–11kW straightening motor: Powerful straightening capacity to efficiently process all rebar sizes within 4–14mm and avoid machine jamming.

Maintenance Reminder
The service life of wear parts for frequency conversion 1000-ton and 2000-ton versions is far longer than the high-speed model (800–1000 tons vs 300–500 tons). For mass production, high-end configurations are recommended to lower unit consumable cost.
Q: How to choose between the high-speed version and frequency conversion version of rebar straightening and cutting machine?
The high-speed model (35–55m/min) features a simple structure and a lower price, suitable for projects with small daily output. The frequency conversion version (0–80m/min or 0–100m/min) supports stepless speed regulation, longer wear part lifespan, and higher cutting precision, ideal for continuous mass processing. If daily processing volume exceeds 10 tons, the frequency conversion model is strongly recommended for better long-term overall cost performance.
Q: Can rebar straightener cutter process round steel and threaded steel simultaneously?
Yes. The YG series straightens and cuts round steel from 4–14mm and threaded steel from 4–12mm. You only need to adjust the gap between feeding rollers and straightening rollers when switching material specifications. Threaded steel has raised ribs on the surface, leading to higher cutting resistance, so its maximum processing diameter is 2mm smaller than round steel.
Q: How long can the measuring accuracy be maintained?
YG equips Cr12MoV measuring rollers with the direct pressure length measuring system. Normally, the measuring accuracy lasts for a full wear part replacement cycle (800–1000 tons for the 1000-ton version, around 2000 tons for the 2000-ton version). Calibrate the length counter every time you replace consumable parts to guarantee accurate cutting lengths.
Q: What is the maximum speed of the frequency conversion 2000-ton model?
The frequency conversion 2000-ton version reaches a maximum straightening speed of 100m/min. Equipped with a 15kW traction motor and 5.5kW cutting motor, one set of wear parts can process about 2000 tons of rebars, making it the highest-capacity configuration in the YG lineup.
