Product Details
The mechanical servo CNC four-roll plate rolling machine is a high-end sheet metal rolling and forming machine featuring an all-steel four-roll configuration, servo motor and precision lead screw drive, and fully automatic CNC control. Combining high precision, clean production and automation, it is a high-end model designed for the batch processing of precision cylinders and curved components.
Principle of Operation (Four-Point Bending)
The sheet is fed between the upper and lower rollers; the lower roller rises to clamp the sheet, whilst the side rollers are raised, enabling the pre-bending of both ends of the sheet in a single loading operation without the need for manual repositioning;
The CNC system precisely controls the synchronised feed of the rollers on both sides, with the upper roller rotating to feed the material, continuously rolling and forming it into cylinders or curved components;
The sheet can undergo multiple cycles of rolling to achieve a circular profile; once processing is complete, the unloading end frame swings open, allowing the cylinder to be removed directly.
