The world's leading heavy-duty vertical metal band sawing machine: Zhejiang Lai'anuo Industry and Trade Co., Ltd.'s milestone work in 2025

In 2025, China's equipment manufacturing industry will once again achieve a breakthrough - the world's largest vertical metal band saw machine, developed and manufactured by Zhejiang Lianuo Industry and Trade Co., Ltd., is about to be completed and planned to be exported to Russia. This device, with its cutting height of 4200mm, cutting width of 4000mm, cutting length of 10 meters, and cutting carrying capacity of 1000 tons, redefines the limits of the metal processing field and is known as the "super giant of industrial cutting". The following is an introduction from the aspects of technical parameters, innovative design, application fields, and market significance.

1、 Breakthrough technical parameters and performance advantages

1. Large cutting size and load-bearing capacity

The maximum cutting height of this device is 4200mm, the width is 4000mm, and the cutting length is 10 meters. It can handle ultra large metal components such as ship keels and nuclear reactor shells. Its load-bearing capacity of 1000 tons supports batch processing of high-density alloy steel, stainless steel, and special metals, meeting the efficient cutting needs of high-strength materials in the heavy industry field

2. Precise cutting and stability

The patented double U-shaped block clamping system is used to achieve dual fixation of the workpiece in both horizontal and vertical directions through the collaborative action of vertical plates, horizontal plates, and auxiliary clamping plates, avoiding displacement or tilt caused by uneven force during the cutting process, and controlling the accuracy error within ± 0.1mm. In addition, the reinforced rib structure and tapered hole auxiliary clamp further enhance the stability and durability of the equipment.

3. Integration of intelligence and automation

Combining CNC system with fully automatic feeding device, the equipment supports preset programmed operations, suitable for batch production of complex cutting paths, significantly improving efficiency and reducing the need for manual intervention.

2、 Highlights of Technological Innovation and Patent Design

1. Patent clamping technology

Drawing on the patent design of a vertical metal band sawing machine described in technical literature (patent number not disclosed), Zhejiang Lianuo has added an auxiliary clamping plate and a conical rod cooperating structure on the basis of the traditional clamping plate. Through the linkage locking of the second U-shaped block and screw, the vertical displacement problem caused by the inclination of the cutting blade during the cutting process of the workpiece is completely solved, especially suitable for stable processing of ultra large workpieces.

2. Modular expansion design

To meet the requirements of workpieces at different heights, the equipment supports the expansion of clamp height through a detachable second vertical plate, which flexibly adapts to diverse workpiece specifications and reduces equipment adjustment time.

3. Application of high temperature and wear-resistant materials

The key components are made of high-temperature resistant alloy steel and surface hardening treatment technology to ensure the service life of the saw blade under long-term high load operation. At the same time, a cooling system is equipped to cope with the heat generated by high-strength cutting.
