1.A solid foundation: Weight and structural design are the cornerstones of quality.
1.1Weight comparison shows the sincerity of materials
Weight is one of the important intuitive indicators to measure the quality of Sheet Metal Bending Machine. Taking the 110T 3200 model as an example, the weight of the Claus Sheet Metal Bending Machine is about 8.2T, while other ordinary brands of the same model of Sheet Metal Bending Machine on the market may only weigh 7.2T. Behind this 1T weight difference is Claus's persistent pursuit of high quality. A heavier body means that more and better steel is used, which can effectively enhance the stability of the machine during operation and reduce the error caused by vibration, thereby ensuring the bending accuracy and processing quality.
In actual production, the Sheet Metal Bending Machine will generate a strong force during operation. If the body is not stable enough, a slight vibration may cause the bending angle to deviate, affecting the dimensional accuracy and appearance quality of the product. With solid materials, the Claus bending machine can still maintain stable operation when facing high-intensity and long-term work tasks, greatly reducing the defective rate and saving production costs for enterprises.
1.2Extra-thick wall panels create a solid body
The structural design of the Krrass Sheet Metal Bending Machine (110T3200) also reflects its extraordinary features, especially the thickness of its wall panels, which is far higher than that of ordinary brands. The thickness of the workbench vertical panel is 80mm, the thickness of the side wall panel is 50mm, and the thickness of the slider is 60mm. Such a thick wall panel not only improves the overall rigidity of the machine body, but also better withstands the huge pressure during the bending process, effectively prevents the deformation of the machine body, and prolongs the service life of the equipment.
Compared with ordinary Sheet Metal Bending Machine, the thick wall panel design of the Kraus Sheet Metal Bending Machine makes it more advantageous when processing high-strength metal sheets. For example, when processing titanium alloy sheets commonly used in the aerospace field, or thick steel plates in the construction industry, the Kraus Sheet Metal Bending Machine can rely on the solid body structure to ensure the precise execution of the bending action, avoid problems such as inadequate bending of the sheet metal and surface damage caused by insufficient body strength, and meet the stringent requirements of high-end manufacturing for product quality.
