parallel thread rolling machine used to make threa

thread rolling machine is used to make parallel thread on head of rebar from diameter from14mm-40mm.the effective length can as long as 100mm. we have JBG-40K JBG-40B JBG-40D JBG-50 thread rolling machine. our products are cheap and have good quality compared with others. thread rolling machine technicial data JBG-40K It not only adjusts freely in the range 14-40mm using the rib-stripping plate but also eliminates the problem that the rebar head with screw head often becomes bigger, further guaranteeing the construction quality.the effective screw head can be 65mm. electric motor power:4KW gross weight:500KG work voltage:3-380V 50HZdimension:1250*1050*750mm rotate speed:60r/minsteel bar standard:14-40mm thread pitch:2.5 3.0 3.5 max thread length:65mm JBG-40D It is easy to adjust; it adds the screw pitch angle mechanism. It is especially fit for the rebar splicing in bridge-piles and tunnel construction.the effective screw head can be 100mm. electric motor power:4KW gross weight:450KG work voltage:3-380V 50HZ dimension:1250*1050*750mm rotate speed:60r/min steel bar standard:14-40mm thread pitch:2.5 3.0 3.5 max thread length:100mm JBG-40B It features that in the same pitch range, the rib-stripping plate can be adjusted freely. The rebar head with screw thread is standard, precise and the service life of the machine is extended.the effective screw head can be 65mm. electric motor power:4KW gross weight:500KG work voltage:3-380V 50HZ dimension:1250*1050*750mm rotate speed:60r/min steel bar standard:14-40mm thread pitch:2.5 3.0 3.5max thred length:65mm client's special requirement are availavle.
