| Thickness of pre-bending|
Min rolling diameters
Small CNC universal upper roller bending machine(Curve down coiling machine) with rolling O type, U type, multi segment R of different shapes.
1.The machine widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and other machinery and equipment. Its working principle is rotating bending deformation.
2. A cylinder can be rolled, including the pre-bending of both ends, feeding the plate forward through the rolls, one time only. The operator should find one only position for each side roll, to get part finished.Permanent lubrication technology(bearing life period without refueling).
2.Totally European design,streamlined looking,frames of our machines are fabricated, welded steel (ST-52). Roll shafts, materials and bearings used in production are European quality. Also the torque limit of the machines is very high. NC playback and CNC graphic control systems are available as optional accessory.
3. The main structure of the equipment includes upper roller, lower roller and horizontal movement mechanism, supporting mechanism,main drive mechanism,downturn system, left and right machine frame, chassis and balance mechanism, hydraulic and electrical control systems.
4. It allows for excellent roundness, thanks to the Planetary movement of the side rolls (Accurl patent), moving them to the center of the machine (the tightest geometry available), compared to the inclined linear guides of other brands that, especially on large diameters, move farther away from the central roll and the plate clamping.clamping pressure is adjustable(no-existent skidding,productivity is 80% than three roller plate rolling machine).
