Types Of Rolling Machine In Metal CNC Rolling Machine Iron Sheet Rolling Machine

1, High Precision end Pre-bending The straight enge length can be set freely, the upper roller press to pre-bend NC Control, high productivity.Parameters are controlled by NC, easy for operation, improve the productivity greatly 2, Good accuracy The upper roller is like a drum, the lower rollers assorted with it through support rollers. Bend continuously, can roll ideal products from thin to thick plates widely 3, Safety The lower rollers are fixed, the upper roller move vertically and horizontally. The job does not work with the working rollers. Complete structure, simple foundation, convenient movement. The machines has unitary basement, does not need earth bolts, has simple foundation

1.Working rollers: cast steel ingot(chemical composition analysis):check performance-forging roughcast-forging annealing-UT flaw-roughing(chemical tests)-heat treatment(hardening and tempering)-UT flaw-semi finishing-finishing-MT.

2..Large forigings: cylinder body, gear, gear shaft forging roughcast-surface imspection-roughing-UT flaw-UT flwa detector hear treatmenat-finishing semi-finishing-MT.

3.Welding structure: racks, chassis, wheel box plate into the factory(chemical compositon analysis, mechanical
test)-pretreatment-for sheet metal cutting-welding-seam UT or RT flaw-annealing treatment-roughing-finishing-vibration
destressing-hot blasting-finishing 5-4 major parts of the manufacturing process.

Discoloration due to quenching treatment of fuselage and rollers, Not easily deformed
