FIMI Cut to Length Line: A Technological Marvel in Metal Processing

I. Introduction

In the world of metal processing and manufacturing, the cut to length line is a crucial piece of equipment that enables the precise cutting of metal coils into specific lengths, meeting the diverse needs of various industries. FIMI, a renowned name in the metal processing machinery industry, has made significant contributions with its advanced cut to length line technology. This article aims to explore the features, advantages, and applications of the FIMI cut to length line in detail.

II. Features of the FIMI Cut to Length Line

A. High-Precision Cutting System

1. State-of-the-Art Cutting Mechanism

The FIMI cut to length line is equipped with a sophisticated cutting mechanism that ensures highly accurate cuts. Whether it is a mechanical shear or a more advanced cutting technology, such as laser cutting (in some of their high-end models), the cutting precision is maintained at an extremely high level. This allows for the production of metal sheets with exact lengths, meeting the strict requirements of different applications. For example, in the automotive industry where components need to fit precisely, the high-precision cutting of the FIMI line is essential to ensure the quality and performance of the final products.

2. Adaptive Cutting Technology

The cutting system is designed to be adaptable to different types of metals and thicknesses. It can handle a wide range of materials, including steel, aluminum, copper, and other alloys, with varying thicknesses from thin sheets to thicker plates. This adaptability makes the FIMI cut to length line a versatile solution for different metal processing needs, enabling manufacturers to process a variety of materials without the need for multiple specialized machines.

B. Advanced Levelling System

1. Progressive Levelling Philosophy

FIMI's cut to length line incorporates a unique levelling philosophy based on the progressive contribution of several levellers in cascade. This approach ensures that the metal coils are flattened and aligned accurately before the cutting process, resulting in a high level of flatness and dimensional accuracy of the cut sheets. The levelling process is crucial for removing any curvature or distortion from the metal coils, which can otherwise affect the quality of the cut pieces. For instance, in the production of metal roofing panels, a flat and accurately levelled sheet is essential for ensuring proper installation and aesthetic appeal.

2. Torque Dynamic Distribution System (TDDS)

The TDDS is a patented system by FIMI that plays a vital role in the levelling process. Special sliding couplings are applied on each exit shaft of the drive unit distributor, which act as connecting elements to the shafts that transmit motion to the flattening rollers. These couplings work in an oil bath in a special tank, ensuring adequate lubrication and cooling conditions. The TDDS enables a homogeneous distribution of the levelling torque among all the working rollers, allowing each roll to assume its own speed depending on the curvature of the strip being levelled. This not only avoids torque conflicts between the various working rolls but also significantly increases the resistance limit of the processable material with the same diameter of the levelling rolls, resulting in a longer life of the working rolls and no scratches on the strip surface.

C. Intelligent Control System

1. Computerized Control and Monitoring

The FIMI cut to length line is controlled by a powerful computerized control system that allows for precise control of all the processes, including coil feeding, levelling, cutting, and stacking. The operator can easily program the desired cutting lengths, widths, and other parameters through the user-friendly interface, ensuring consistent and accurate production. Additionally, the control system continuously monitors the operation of the line, detecting any deviations or malfunctions in real-time and providing alerts for timely maintenance and troubleshooting.

2. Data Management and Analysis

The intelligent control system also has the ability to collect and manage data related to the production process, such as cutting speeds, material usage, and quality parameters. This data can be analyzed to optimize the production process, identify areas for improvement, and make informed decisions for future production runs. For example, by analyzing the data on cutting speeds and material thickness, the manufacturer can determine the optimal settings for different materials to maximize productivity and minimize waste.

III. Advantages of the FIMI Cut to Length Line
