ERW60 High Frequency Square Tube Mill for Round and Rectangular Pipes

The ERW60 pipe making machine is a high precision tube mill line used to produce building materials pipes, widely applied for construction materials, drainage systems, energy supply pipes, building and decoration profiles, extruded profiles, and cold bending profiles.

Product precision reaches 0.03 mm (ERW32/ERW50/ERW60), with accuracy exceeding 0.05 mm for ERW76 units.

• High precision: Level roller jumps 0.01, frame and slide clearance ≤0.02, frame vertical degree ≤0.05, each frame parallel degree ≤0.1, steel pipe diameter and roundness error ≤0.08
• Incorporates Japanese technology to meet high accuracy requirements for international clients
• Features schedulable worm gear and worm adjustment for precise, energy-efficient operation
