What are the applications of high-speed steel sharp edged knives in the mechanical processing indust
High speed steel sharp edged knives are suitable for processing metal and non-metal materials with moderate hardness due to their high hardness (up to 63-66 HRC after heat treatment), high wear resistance, good red hardness, and high sharpness of the cutting edge. The core application scenarios in the mechanical processing industry are as follows:Sources：www.kmjjw.cn | PublishDate：2025.12.23
1. Chamfering and deburring of precision small parts
This is the main application scenario of high-speed steel sharp edged knives. For small workpieces such as instrument parts, electronic connectors, precision mold accessories, etc., sharp angle chamfering (such as 0.5 ° -15 ° small angle chamfering) and removal of orifice sharp angles can be carried out with sharp cutting edges to avoid edge breakage or deformation of the workpiece, ensuring the assembly accuracy and appearance cleanliness of the parts.
2. Sharp corner cleaning and groove cutting in mold processing
In the cavity processing of injection molds and stamping molds, it is used to clean the sharp corner allowance at the junction of the mold surface and the side wall, and to process sharp edges or narrow grooves that meet the design requirements (groove width can be as small as 0.1-0.5mm). Compared to hard alloy cutting tools, high-speed steel sharp edged tools have better toughness and are less prone to chipping during small cutting operations, making them suitable for precision machining of mold parts.
3. Carving and marking of non-ferrous metals
For non-ferrous metal workpieces with low hardness such as copper, aluminum, and zinc alloys, high-speed steel sharp edged knives can be used for surface engraving, pattern carving, and other processing. For example, when carving text or patterns on hardware accessories, nameplates, and instrument panels, the sharp blade can produce clear and delicate lines, and the cutting process is not easy to stick to the blade, ensuring a smooth carving surface.
4. Cutting of non-metallic materials such as wood and plastic
In addition to metal processing, high-speed steel sharp edged knives are also suitable for processing non-metallic materials such as hardwood and engineering plastics (such as ABS, acrylic), such as making sharp edged shapes for wooden models and processing sharp edged features for plastic parts. The sharpness of cutting tools can reduce the tearing phenomenon of non-metallic materials and improve the surface quality of machining.
5. Trial production and processing of small-scale non-standard parts
For the processing of small batches and multiple varieties of non-standard parts, the advantages of low cost and convenient grinding of high-speed steel sharp edged knives are prominent. Operators can adjust the sharpening angle of the blade according to their needs, adapting to the processing requirements of different workpieces without the need for frequent replacement of specialized tools, reducing the cost of cutting tools for small-scale production.
