Fengjinrui, a professional enterprise deeply engaged in the field of precision cutting tools and saw blades, is committed to providing customers with one-stop sawing solutions that can significantly reduce costs. We focus on the research and development, production, sales and grinding services of aluminum saw blades, and take this as the core to continuously explore and innovate. Our products are extensive, including boss ultra-thin saw blades, Fuji brand thin saw blades, aluminum cutting saw blades, etc., to meet various sawing needs. At the same time, we also provide value-added services such as imported saw blade agency, saw blade grinding and tooth filling to ensure that customers’ sawing efficiency and cost-effectiveness are maximized.

02Challenges and Countermeasures of High-Speed Hacksaw Blades

However, facing the wear problem of high-speed steel saw blades, we are well aware that technology alone cannot completely avoid it. Before a breakthrough in material technology, the wear of high-speed steel saw blades will inevitably exist. But it is this challenge that inspires our determination to continue to explore and strive to provide customers with better quality and more durable saw blade products. High-speed steel saw blades are named for their unique heat treatment method, that is, no liquid cooling is required, only natural cooling in the air can complete the cooling process of the entire saw blade. Although its hardness is far higher than that of ordinary carbide saw blades, in actual use, it is still inevitably affected by certain unexpected factors, resulting in damage.

It can be understood that from the manufacturing process of high-speed steel saw blades, to their logistics and transportation, and then to actual use, each link may have an impact on the wear of the saw blades. During the logistics and transportation process, the packaging method and placement of the saw blades will affect their stress state. In the use stage, high-speed steel saw blades need to withstand severe tests, especially the mechanical impact between the saw blades and the cut materials, which is an inevitable source of wear. In particular, the saw teeth of the high-speed steel saw blades are under tremendous pressure during the frequent cutting process. The entire process of cutting materials is full of challenges, among which the saw blade speed, feed speed, and the skill level of the operator will directly affect the operating state of the saw blade. It can be seen that the wear problem of high-speed steel saw blades is everywhere and almost impossible to avoid completely. However, when the saw blade is worn, how to effectively use the saw blade grinding technology will directly determine the operating cost of the enterprise. In addition to the option of direct scrapping, saw blade grinding is undoubtedly a more economical solution.

03Advantages and technologies of saw blade grinding

At present, many companies engaged in metal pipe sawing and processing have gradually realized that worn high-speed steel saw blades are actually a reusable resource. They have long benefited from the economic benefits brought by saw blade grinding technology. During the grinding process, saw blade grinding manufacturers will carefully check the wear condition of the saw blade and mark the damaged parts in detail. It is worth noting that the premise of saw blade grinding is that the high-speed steel saw blade is repairable. For those high-speed steel saw blades that are worn beyond repair, grinding loses practical significance.

During the grinding process of high-speed steel saw blades, the wear of the teeth is the core of the grinding work. In addition, for those high-speed steel saw blades with fallen teeth, tooth filling is also feasible. Grinding a high-speed steel saw blade requires 18 processes, and each one is crucial. After such fine grinding, the cutting performance of the high-speed steel saw blade can be restored to more than 85% of its original state. This means that the company can save more than 10,000 yuan in saw blade procurement costs every day. In essence, the grinding of high-speed steel saw blades is an effective use of resources, which deeply explores the potential surplus value of the saw blade. As more and more companies realize the benefits of grinding, the cost of purchasing new saw blades is gradually decreasing.
