Model 120 Series CNC Precision Leveler

Product Introduction

The Model 120 Series CNC Precision Leveler stands as a titan in the realm of heavy industrial metal processing, engineered specifically to master the formidable challenges posed by extra-thick plates and ultra-high-strength structural steels. As a flagship offering within our standard series, this machine transcends the capabilities of conventional leveling equipment, providing an uncompromising solution for sectors where material flatness and internal stress relief are paramount. At the core of its design lies a colossal 120mm diameter roll system, meticulously arranged in a 19-roll heavy-duty configuration. This architecture is not merely a specification but a calculated engineering feat, designed to deliver immense specific pressure capable of penetrating deep into the material cross-section to correct inherent internal stresses.

Optimized for working widths spanning 400mm to 2100mm, the Model 120 is built to accommodate the rigorous demands of modern heavy fabrication. It excels in processing materials with a standard thickness range of 4.0mm to 16.0mm, with a maximum capacity reaching up to 25.0mm for specific high-yield applications. The machine’s robust construction ensures that even the most warped or stressed plates emerge with exceptional flatness, meeting the stringent quality standards required in critical infrastructure projects. With a minimum workpiece length capability of 190mm, it offers surprising versatility for a machine of its class, allowing for the processing of shorter, high-value components often found in complex assemblies.

Product Advantages

Unmatched Structural Rigidity and Roll Strength

• The defining characteristic of the Model 120 is its sheer physical presence and strength. The 120mm diameter rolls are crafted from high-grade alloy steel, undergoing advanced heat treatment to ensure exceptional wear resistance and toughness. Unlike smaller series, the 120 Series utilizes a reinforced monoblock frame design that virtually eliminates frame deformation under maximum load. This ensures that the leveling force is applied consistently across the entire width of the plate, preventing edge waves and center buckles even when processing wide, thick sections. The 19-roll configuration provides a high degree of redundancy and support, ensuring smooth material flow and superior flatness correction for heavy plates.

Superior Performance on High-Strength Materials

• This series is specifically tuned for the "hard-to-handle" materials that define modern engineering. Whether processing Hardox, Q690, or high-tensile structural steels, the Model 120 delivers the necessary torque and roll pressure to yield the material effectively. The drive system is engineered with high-tolerance gearboxes and heavy-duty couplings, capable of transmitting the massive power required to flatten thick, high-yield plates without stalling or slippage. This capability makes it an indispensable asset for manufacturers supplying the mining, defense, and heavy transport industries, where material strength cannot be compromised for flatness.

Precision Engineering for Thick Plate Applications

• While many levelers struggle with the "spring-back" effect common in thick plates, the Model 120 utilizes a precise roll gap control mechanism (manual or motorized adjustment based on configuration) that allows operators to dial in the exact reduction ratio required. The large roll diameter provides a larger contact area, which is crucial for distributing force evenly on thick materials, thereby reducing surface indentation risks while maximizing shape correction. This results in a finished product that is not only flat but also free from internal stresses that could cause distortion during subsequent welding or cutting processes. 

Optimized for Heavy-Duty Production Environments

• The Model 120 is built to survive and thrive in harsh industrial environments. Key components are shielded against dust and debris, and the lubrication system is designed for continuous heavy operation. The machine’s design prioritizes accessibility for maintenance, ensuring that critical wear parts can be inspected and replaced with minimal downtime. Its variable speed control, ranging from 1 to 10 meters per minute, allows operators to slow down the process for extremely thick or difficult materials, ensuring the highest quality finish, or speed up for lighter loads within its range to maximize throughput.
