Hydraulic CNC 4-Roller Rolling Machine — Technical Specifications
The rolling machine is composed of an upper shaft, lower shaft, and side shafts. Shaft material is 42CrMo with medium frequency surface treatment, heat treated to HRC54-56 hardness, and hard chrome plated after finishing to ensure surface finish of 0.8. The machine is driven by a hydraulic drive unit. Clamping and side roller lifting/lowering are controlled by cylinders (two cylinders per axis), with synchronization achieved through the hydraulic balance system and electrical control system.
Additional Functions: Beam pickup function prevents winding overlap when rolling different size cylinders. Automatic discharging pushes finished rolled products to a liftable receiving platform.
