Production flow of rebar coupler:
Step 1:Cutting steel tube or solid bar by ATM cutting machine according to needed length;
Step2: For solid bar we use drilling machine to bore holes(for steel tube, this step is not needed);
Step3: Use ATM chamfering&flaying machine to chamfer and peel ribs on the unfinished couplers(some customers donot need this step);
Step4: Then atm or semi-atm coupler threading machine makes internal threads onunfinishedcouplers(This step is most important)
Step5:Make mark on finishes couplers by Laser engraving machine(some customers donot need mark)
Step6:Testing coupler length by callipers and thread size by screw gauge.
Step7:Packaging and loading.
