HAIHUI · REBAR PROCESSING GUIDE
A rebar band sawing machine should be selected by the complete stock arrangement, steel grade and required cut quality. Individual bar diameter alone does not establish whether a bundle can be cut securely. Haihui supplies 4240 / 4250 band saw options for reinforcement preparation from Xingtai, Hebei, China.
What the 4240 cutting envelope means
The current Haihui product sheet lists a 330 × 370 mm maximum cutting capacity for the 4240 configuração de referência. This describes the cutting envelope; it is not a rating for a single 370 mm reinforcing bar. A proposed bundle must fit the confirmed envelope and allow secure clamping throughout the cut. The photographed 4250 model requires its own specification confirmation.
Prepare a bundle-cutting enquiry
State bar grade, diâmetro, bars per cut, bundle width and height, target cut length and cuts per shift. Include how stock arrives and how short offcuts will be removed. Ask whether the clamping arrangement can restrain the actual stock pattern, including the last short length. A configuration suitable for one bundle shape may not suit another.
Compare blade speed with finished output
O 4240 reference lists blade speeds of 40 / 60 / 80 m/min, um 4 kW main motor, hydraulic clamping and electric feeding. Blade speed measures blade travel, not stock feed or completed cuts per minute. Tooth pitch, material section, blade condition, coolant and handling all affect the production cycle. Confirm the coolant system and specified fluid rather than assuming that the category name “water sawing” means plain water.
Inspect a trial cut
Use representative material and record the actual bundle arrangement. Inspect cut length, end squareness and burrs, then include loading, clamping and unloading in the timed cycle. If cut bars will enter a threading station, agree the end-preparation requirement with the coupler process supplier. Confirm support-stand length, electrical supply and consumables in the quotation.
