The advancement of cutting shears blade technology and processing capabilities signifies a continuously expanding potential for manufacturers still using outdated cutting shears blades or special-purpose shears blades. These shears blades are often specifically designed for certain components or series of components, which means that each dimension on a component requires a different shears blade for processing when used as a rotating blade in a machine processing center.
The development of new shearing blade for cutting machines offers higher cutting capabilities and easier operation, thanks to the advancements in design and production technology. This has enabled the application of precise blades and shearing blades, thereby improving machine tool utilization, increasing output, and enhancing the reliability of the machining process.
Standardization is crucial in manufacturing, as it is only through standardization that technicians can communicate in a single language and understand applications. However, in some cases, standards may slow down or even hinder the pace of product development. It is then necessary to break free from constraints and barriers, and introduce better solutions. One such example is the development of shearing machine blades.
For many years, users have interchanged cutting blades produced by various manufacturers for shearing machine blades, following standard specifications. However, these standards impose various restrictions on shearing machine blades, defining their shape, thickness, and the inner circle of the cutting edge, as well as the dimensions of the blade holder and wedge clamp components, and the blade body size. Due to the limited design range of blade material, blade edge, and chip-breaking groove, suppliers and users adhering to the standards are subject to limitations in machining performance.
Today's shearing blade for cutting machines is continuously being optimized to meet the needs of modern production, machine tools, and materials, and is widely accepted across the industry. Approximately 80% of the shearing blade products supplied by Sandvik CoroPlus are shearing blades, with the majority developed in the past 10 years. Compared to older models, the new shearing blades increase metal removal rates several times over, have less cutting force and better directionality. Their typical跳动量 is just a fraction of the old standard shearing blades, allowing for consistently tighter machining tolerances and less, more ideal blade wear. Both axial and radial跳动量 are minimal, indicating improved cutting edge precision, leading to better surface quality of workpieces, tighter tolerances, longer life of the shearing blades, and more even distribution of cutting loads. This results in increased cutting speed, reduced noise, vibration, and wear.
Today, the concept of shearing blade for plate cutters has become more flexible, providing developers with the freedom to adopt new shearing blade designs and technologies. These innovative designs can be optimized to enhance the safety, precision, surface quality, metal removal rate, blade overhang, high-speed cutting, and the ability to handle different cutting paths of shearing blades.
The new cutting shears blades utilize material and slotting designed specifically for the cutting process, delivering superior performance and outcomes compared to standard shearing blades. These modern, new shearing blades, when paired with the corresponding blades, offer greater positive rake angles and more complex cutting geometries, significantly reducing cutting forces. This synergy results in faster and more stable metal removal, outperforming most standard shearing blades.
Outdated cutting shear blade technology can have severe consequences for the economic benefits and production safety of machine processing. If machine processing companies continue to use cutting shear blades that are behind the latest technological advancements, they will gradually lose production capacity and competitiveness. Moreover, simply purchasing advanced cutting shears without promptly updating the blades is akin to half-hearted effort and half measures.
