With the continuous advancement of industrial manufacturing technology, band saw blades, as an important cutting tool, have also undergone significant evolution in their manufacturing materials and processes.
Today, let's take a look at what is the difference between the raw materials used to make bimetal band saw blades in the early days and the bimetal strips?
In the early days, band saw blades were mainly made of a single material, such as high carbon steel or high-speed steel.
Traditional processes are mostly integrally formed, or simply combining high-speed steel sheets with base bands through welding technology.
Although this method was able to meet basic cutting needs at the time;
It had obvious shortcomings:
◆ Low durability: It is difficult for a single material to take into account both sharpness and toughness at the same time, and it is easy to wear or break under high-load working conditions.
◆ Limited cutting accuracy: The integrally manufactured band saw blades are prone to uneven blades or deformation during processing, resulting in unsatisfactory cutting results.
◆ Poor production consistency: The limitations of the welding process make it difficult to guarantee the performance stability and consistency of each saw blade.
Advantages of modern bi-metal strips
With the development of material science and process technology, modern band saw blades generally use bi-metal strips as semi-finished products.
Through advanced heat treatment, explosive welding or rolling process, high-hardness and wear-resistant high-speed steel is firmly combined with high-toughness base steel to achieve complementary advantages.
The main advantages include:
◆ High wear resistance and long life: The high-speed steel blade remains sharp, significantly extending the service life of the band saw blade and reducing the frequency of replacement and maintenance.
◆ Excellent cutting performance: The composite structure ensures the sharpness of the blade and the toughness of the base belt, making the cutting process smoother and more precise, and suitable for various high-strength materials.
◆ High production stability: Modern composite technology ensures uniform performance of each batch of products, which helps to improve overall production efficiency and product quality.
◆ Environmental protection and energy saving: Due to the extended product life, waste generation and energy consumption are reduced, which is in line with the current green manufacturing trend.
Summary
Overall, although the early band saw blades had certain practical value under the technical conditions at the time, due to the limitations of manufacturing processes and materials, their durability, cutting accuracy and consistency were insufficient.
Modern bimetallic composite belts, with advanced composite technology, not only improve the overall performance of band saw blades, but also show obvious advantages in environmental protection, energy saving, production stability, etc. This technological innovation provides various saw product manufacturers with higher value-added material options and also promotes the entire industry to develop in the direction of intelligence, efficiency and greenness.
Through comparison, we can see how technological progress changes traditional processes and brings new solutions and market competitiveness to industrial manufacturing.
