EZW43V-40x1600 11-Roll Plate Levelling Machine | EZHONG, Hubei, China

EZHONG EZW43V-40x1600 11-Roll Plate Levelling Machine – Servo-Controlled Levelling up to 40 mm

The EZHONG EZW43V-40x1600 is an eleven-roll CNC plate levelling machine for plate up to 40 mm thick and 1,600 mm wide. Servo drives position the work rolls and control the roll gap precisely, so the machine adapts quickly to different thicknesses and materials, while a PLC stores and recalls levelling recipes. Its optimised frame gives stable levelling at full load with no special foundation, and a movable beam with generous lift makes roll changes and maintenance fast. It suits fabricators and manufacturers in automotive, wind power, pressure vessel and shipbuilding work who need flat, stress-relieved medium plate.

How It Levels

• The first working rolls bend around 50–55% of the plate thickness into the plastic range
• Each following roll bends the plate a little less, until the final bend is purely elastic
• This controlled reduction releases internal stresses evenly across the plate
• Roll spacing and diameter are optimised for medium loads, so the machine handles both thin and medium-thick plate

Key Features

• Levels plate up to 40 mm thick and 1,600 mm wide
• Servo-driven reduction and roll gap control for accurate roll positioning
• Individual roll drive improves grip on the plate and reduces slipping
• High-precision rolling bearings on the roll journals for low friction
• Optimised frame for stable force transmission and high rigidity, with no special foundation needed
• Movable beam with optimised lift for quick roll changes and maintenance
• Automatic centralised electric lubrication for work rolls, back-up roll bearings, gearboxes and lead screws, each on a separate line
• Digital display of upper roll stroke to ±0.1 mm
• Single-operator use
• Built to EC safety standards with CE certification

Control and Safety

• High-performance PLC from an international brand
• Entry and exit roll gaps set from plate thickness, width, material and original flatness
• Save, edit and recall process parameters at any time
• Guards over roll drive shafts and gears
• Photoelectric safety sensors at the feed and discharge sides

Work Roll Quality

• 50CrNiMo alloy steel rolls to JB/T 3164-2007
• Quenched and tempered to HBW 270–300, surface hardened to HRC 52–58 (HS 80–90)
• Hardened depth of 2–4 mm (rolls up to 150 mm diameter) or 4–6 mm (over 150 mm)
• Ground to h6 tolerance, Ra 0.8 μm finish
• Manufacturing route: forging, annealing, rough turning, quenching and tempering, semi-finishing, surface hardening, fine grinding
• Three inspections (after blanking, rough machining and finishing), with material, heat treatment and flaw detection reports supplied

Frequently Asked Questions

• What plate sizes can it level? Up to 40 mm thick and 1,600 mm wide.
• What makes it different from EZHONG's other levellers? Servo-driven roll gap control, 50CrNiMo work rolls, and a narrower 1,600 mm width suited to medium plate and cut blanks.
• Does it need a special foundation? No. The frame is designed to level stably at full load without special foundation reinforcement.
• How are the rolls maintained? A movable beam gives easy access for roll changes, and automatic centralised lubrication covers rolls, bearings, gearboxes and screws.
• Can it store settings for different jobs? Yes. The PLC stores, recalls and edits levelling parameters by thickness, width and material.
• What should I send for a quotation? Plate grades and yield strength, thickness and width range, required flatness and throughput, and your local voltage and frequency.
