In order to extend the service life of the tool, it is necessary to select a reasonable type of metalworking fluid and optimize the processing method. This is especially true for difficult-to-process materials. When cutting difficult-to-machine materials, high-quality cutting fluid is required. The

In order to ensure the welding quality of the steel inserts, the welded blades should be carefully inspected to find out the causes of defects and improve them. Before the inspection, the steel insert blade should be sandblasted or lightly ground to remove the solder and impurities adhering to the b

1. Slitting knifeThe slitting blade is mainly used for slitting paper, film, gold, silver foil, copper foil, aluminum foil, tape, and other items. The slitting of these objects requires the blade to have the least cutting resistance and the greatest wear resistance. Due to the requirements of produc

In order to meet the needs of the international cutting tool market, Nanjing Jingfeng Cutting Tool Company has developed HSS steel round knives, with an outer diameter of 200∼400mm, a thickness of 5∼10mm, and an inner hole of 145∼254mm. The round blade requires a hardness of 62.5∼64HRC; flatness and
