A rebar straightening machine’s nominal feed speed is not the same as accepted cut bars per shift. Haihui’s 85 m/min model lists a 5–14 mm reference bar range, subject to material suitability. Use speed as one input, then evaluate cutting, handling and inspection for the real job.
Make the units explicit
The 85 m/min designation describes nominal maximum material feeding speed. It is not an 85 m bar length or 85 finished bars each minute. Specify the steel grade, diameter and required lengths before discussing output. Straightness and cut-length requirements also affect the production settings that can be used.
Use arithmetic only as a preliminary limit
For illustration, 85 m/min divided by a 5 m cut length gives 17 lengths per minute before any cutting or handling losses. This is a theoretical calculation, not a machine performance promise. The actual result needs a representative run using the confirmed material, configuration and settings.
Include the work around the cutter
Measure coil changes, setup, cutting cycles, sample checks and finished-bar collection. A receiving arrangement that is suitable for one length may not handle another batch conveniently. Clarify the minimum and maximum cut lengths and how completed quantities are separated and identified.
Count accepted output over a defined interval
Agree which measurements determine acceptance, record rejected bars and include the full interval used for the count. Ask for output tied to a particular drawing and material. The Haihui reference listing gives a 15 kW traction motor and a 5.5 kW cutting motor; motor ratings alone do not establish shift output.
Frequently asked questions
Can I multiply nominal feed speed by working hours to promise daily production?
That ignores cutting, changes, handling and rejected material. Use a documented representative production trial for a realistic estimate.
How can I request a factory quotation?
Send dimensioned drawings, material grade and sizes, required quantities, local power supply and the destination country. Ask Haihui to confirm configuration, accessories, inspection requirements and delivery terms in writing.
