HAIHUI · REBAR PROCESSING GUIDE
A rebar straightening and cutting machine converts coiled reinforcement into straight cut lengths. When a workshop has many lengths to produce, batch planning and collection can matter as much as nominal feed speed. Haihui’s 85 m/min model provides a useful reference for planning the coil-to-bundle workflow.
Start with the current machine specification
The Haihui listing gives a 5–14 mm bar range, subject to material suitability, a nominal maximum feed speed of 85 m/min, variable-frequency speed adjustment, a 15 kW traction motor and a 5.5 kW cutting motor. Machine weight is listed as 1380 kg. Confirm cut-length limits, tolerance and material strength for the order.
Build a cut list before setting quantities
Group jobs by material grade and diameter, then identify each required cut length and quantity. Assign a job identifier that stays with the collected bars. This reduces the risk of mixing visually similar lengths. Whether a controller stores several jobs or runs one length at a time must be confirmed for the selected configuration.
Separate theoretical feed from accepted output
As an illustration only, 85 m/min divided by a 5 m cut length gives 17 lengths per minute before cutting and handling losses. This is arithmetic, not a promised production rate. Cutting cycles, straightening settings, coil changes, inspection and collection reduce the usable result. Shorter lengths can make the cutting cycle more significant.
Plan collection for the longest and shortest bars
Specify the full cut-length range and ask for a suitable support and collection arrangement. Clarify how operators identify completed batches and remove them without disrupting the feed path. Keep the receiving area clear and use the supplied operating procedure for access around moving stock. Confirm whether collection equipment is included.
Approve a representative mixed batch
Use actual material and include both common lengths and the most demanding length in the trial. Measure straightness and cut length using the agreed method, record rejected pieces and time complete batch changes. Keep the setup and material record for repeat orders.

Frequently asked questions
Does 85 m/min mean 85 finished bars each minute?
No. It is a nominal feed-speed figure. Bar length, cutting cycles, handling and acceptance checks determine finished output.
Can this machine bend the straight bars into stirrups?
The listed operation is straightening and cutting. Stirrup production requires suitable bending equipment.
