Model 150 Series CNC Precision Leveler

Product Introduction

The Model 150 Series CNC Precision Leveler represents the apex of heavy-industry metal fabrication technology, meticulously engineered for the most demanding applications involving super-heavy plates and extreme-strength alloys. As the penultimate model in our standard series, sitting just below the ultra-heavy 200 series, the Model 150 is a powerhouse designed to bridge the gap between standard structural manufacturing and massive-scale industrial projects. The defining characteristic of this machine is its colossal 150mm diameter roll system. Unlike lighter series, the Model 150 employs a specialized roll configuration—available in 15 or 19 rolls depending on the specific precision requirements—which is calculated to exert maximum specific pressure. This immense force is necessary to penetrate the core of thick materials, effectively altering the internal stress distribution to achieve permanent flatness.

Designed for working widths ranging from 400mm to 2100mm, this series is capable of processing materials with a rated thickness of 6.0mm to 25.0mm, with a maximum capacity reaching 30.0mm. It is built to handle the rigorous processing of high-tensile steels, including Q690 and Hardox, which are standard in heavy machinery and defense applications. The machine operates at a variable linear speed of 1-10m/min, allowing operators to fine-tune the process for optimal surface quality and dimensional accuracy. The integration of CNC technology ensures that the massive forces involved are applied with surgical precision, making the Model 150 an indispensable asset for any facility dedicated to heavy structural integrity.

Product Advantages

Unmatched Structural Rigidity and Frame Design

• The primary advantage of the Model 150 lies in its monolithic structural design. To counteract the immense reactive forces generated when leveling 30mm thick plates, the machine features a heavily reinforced welded steel frame that has undergone vibration aging and stress-relief annealing. This ensures that the frame itself remains distortion-free under maximum load, guaranteeing consistent flatness results over decades of operation.

High-Torque Independent Drive System

• Unlike lighter models that may utilize chain drives, the Model 150 is equipped with a high-torque, all-gear drive system (or heavy-duty universal joint drive depending on configuration). This ensures that power is transmitted synchronously to the work rolls without slippage or backlash. This advantage is critical when processing short workpieces (minimum length 250mm), as it prevents material jamming and ensures smooth entry and exit of heavy, rigid plates.

Optimized Roll Arrangement for Deep Penetration

• The Model 150 offers a choice between 15 and 19 rolls. This flexibility allows users to prioritize either deep stress correction (15 rolls) for very thick plates or higher surface flatness (19 rolls) for precision structural parts. The large roll diameter provides a larger contact arc, which is essential for effectively stretching the fibers of thick materials beyond their yield point without damaging the surface.

Robust Support and Backup Roll System

• To prevent roll deflection (bending) in the middle of the sheet—a common issue with wide, thick plates—the Model 150 utilizes a dense array of backup rollers and heavy-duty bearing seats. This support system ensures that the leveling pressure is evenly distributed across the entire width of the sheet, eliminating "center buckles" or edge waves even on the widest 2100mm cuts.

Technical Specifications

Product Applications

The Model 150 Series is the industry standard for sectors that cannot tolerate material deformation. Its primary applications include:

• Heavy Construction Machinery: Leveling chassis frames, excavator arms, and crane booms where structural integrity is safety-critical.

• Shipbuilding and Offshore Engineering: Processing deck plates, hull sections, and offshore platform components that require strict flatness for welding assembly.

• Wind Energy and Power Generation: Manufacturing flanges and towers for wind turbines, which involve extremely thick, high-strength circular sections.

• Defense and Military: Fabrication of armor plate and heavy transport vehicle components.

• Steel Service Centers: Pre-processing of heavy hot-rolled coils and plates for distribution to various heavy industries.
