Principles of three-roller cold rotary flow forming

Industrial flow forming on Weber Comechanics series 3R machines utilizes cold plastic deformation of tubular preforms. Three synchronized forming rollers arranged symmetrically at 120-degree intervals apply intense radial pressure against a rotating mandrel.

As the carriage traverses along the workpiece axis, wall thickness decreases while overall length elongates without material loss. This cold working mechanism refines grain microstructure, increases tensile yield strength, and yields seamless cylindrical shells with superior internal surface finish.

Precision metal spinning dynamics on dual-roller configurations

Dual-roller spinning on series 2R equipment balances radial forces across the workpiece diameter. Two opposed forming slides work in tandem, cancelling deflection forces on the headstock spindle.

This opposed roller geometry enables precision spinning of deep contours, hemispherical domes, and venturi throats from flat sheet blanks. Dynamic feed servos control roller trajectory along programmed curvilinear paths, maintaining uniform material flow and minimizing localized thinning.

Heavy-duty universal spinning for large-diameter dished heads

Series 1R universal spinning machines accommodate blank diameters up to 3500 mm for pressure vessel dished heads, ventilation housings, and industrial cones. A rigid machine structure absorbs heavy forming moments generated during heavy spinning operations.

The hydraulic tailstock exerts clamping forces up to 150 kN to secure the center blank against the forming chuck. Variable spindle drives maintain optimal surface cutting speeds across varying forming diameters.

Tube end necking and pressure vessel closure technology

Series 2RN spinning machines perform automated closing and necking of tubular blanks for gas cylinders, accumulators, and fire extinguisher shells. Spinning rollers progressively form the open tube end into hemispherical closures and threaded boss geometries under hot or cold conditions.

Automated induction heating units raise blank temperature prior to forming, reducing required roller thrust and ensuring homogeneous material fusion at the vessel pole.

Multi-axis CNC turning and milling machining centers

Weber Comechanics CNC machining centers deliver high-precision cutting operations for complex machine components, alloy housings, and drive shafts. Rigid machine bedways and high-torque direct-drive spindles provide stable cutting performance during heavy milling and fine finishing passes.

Integrated tool probing systems automatically detect tool tip wear and thermal drift, compensating axis offsets in real time to sustain tight manufacturing tolerances.

Automated robotic welding and workpiece positioning cells

Robotic welding cells combine articulated six-axis industrial manipulators with programmable dual-axis positioners for automated welding of heavy fabrications. Digital pulse welding power sources maintain precise droplet transfer, minimizing spatter and heat-affected zones.

Seam tracking optical sensors dynamically correct torch trajectory along joint seams, ensuring full-penetration welds across structural assemblies and tubular frames.
