4 Roller Plate Rolling Machine

W12-25*3000 rolling machine
1, summarize:
This four rolls bending machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical.
Top roll is main drive rolls, it can does vertical and level motion, up and down, parallel translation is display. This machine include pre-bending function.
