60 Series CNC Precision Leveler

Product Introduction

The Model 60 Series CNC Precision Leveler stands as a definitive solution for heavy industrial manufacturing, specifically engineered to address the complexities of processing thick, high-strength metal plates. As a cornerstone in the standard series, this machine is built to tackle the challenges associated with high-yield-strength materials and substantial thicknesses. At its core lies a robust 60mm diameter roll system, configured in a specialized 19-roll heavy-duty arrangement. This specific architecture is optimized for standard working widths ranging from 400mm to 2100mm, providing a versatile platform for diverse industrial applications. The Model 60 is rated for a material thickness range of 1.0mm to 6.0mm, with a formidable maximum capacity of up to 12.0mm, making it the definitive solution for heavy machinery, shipbuilding components, and large-scale structural steel fabrication.

Unlike lighter models, the Model 60 prioritizes torque and structural rigidity. The 19-roll configuration ensures that even at maximum thickness, the material undergoes sufficient alternating bending to eliminate internal stresses, coil set, and crossbow defects. This results in a finished product with exceptional flatness, ready for laser cutting or welding without secondary operations.

Product Advantages

Optimized 19-Roll Heavy-Duty Architecture

• Diverging from the high-frequency, small-curvature design typical of thin-plate levelers, the 60 Series employs a 19-roll high-pressure penetration principle. Through the precise staggered arrangement of upper and lower roll rows, the machine applies immense alternating bending moments to the thick plate. This ensures that stress relief penetrates deep into the material's core rather than merely affecting the surface, thoroughly resolving the industry-wide pain point of "surface flat but internally warped" common in thick plate processing.

Fully Closed-Loop Hydraulic Servo Control

• The equipment abandons traditional mechanical limit adjustments in favor of a high-response hydraulic servo system that directly drives the lifting of the upper roll assembly. Coupled with high-precision displacement sensors, the system provides real-time feedback on the actual roll gap position, establishing a fully closed-loop control mechanism. This guarantees that any frame deformation caused by hundreds of tons of leveling force is compensated for in real-time, ensuring the stability of processing precision.

High-Torque Drive & Gearbox System

• Processing 12mm thick plate requires immense force. The Model 60 is equipped with an industrial-grade high-torque gearbox and a heavy-duty drive system. This ensures stable power transmission even when leveling high-yield strength steels (like Q345 or Q460), preventing stalling and ensuring consistent surface quality without slippage marks.

Super-Rigid Pre-stressed Frame

• The frame is engineered using Finite Element Analysis (FEA) optimization, utilizing an integral cast steel or high-strength steel plate welded structure that undergoes overall annealing to eliminate welding stresses. A unique pre-stressed tie-rod structure further reinforces the frame's resistance to deformation, ensuring that the parallelism of the roll system remains uncompromised even under extreme loads.

Product Applications

The Model 60 Series is strategically positioned to serve industries where structural integrity and flatness are non-negotiable:

• Heavy Machinery & Construction Equipment: Essential for leveling chassis components, boom arms, and outrigger pads for excavators and cranes, where flatness directly impacts welding quality and assembly precision.

• Shipbuilding & Marine Engineering: Ideal for processing deck plates, bulkhead sections, and structural stiffeners. The ability to level thick steel (up to 12mm) ensures that hull sections fit together perfectly, reducing rework during assembly.

• Pressure Vessels & Boilers: Critical for flattening end caps and cylindrical sections before rolling or welding. Removing internal stress prevents distortion during the subsequent high-heat processes involved in boiler manufacturing.

• Steel Service Centers: A vital asset for service centers distributing cut-to-length plates. It transforms coiled heavy plate into pristine, flat sheets ready for laser cutting or plasma cutting, significantly enhancing the value of the distributed material.
