Ltd. "IZPM" makes delivery of high-speed steel tool:
Speed steel - alloy steel designed primarily for the manufacture of cutting tools operating at high speeds. High speed steel should have a high breaking strength, hardness (as cold and hot) and red hardness. High hardness and fracture resistance in a cold state and have carbon tool steel. However, tools are not able to provide high-speed cutting conditions. Doping of high-speed steel tungsten, molybdenum, vanadium and cobalt provides hot hardness and red hardness of steel. Through this doping in HSS hardness in hot state is retained when heated 500-600 ° C. The tool of high speed steel is more productive than that of carbon steel tool.
Of high-speed steel manufactured mainly end tools (taps, drills, small diameter cutters)
The following recommendations exist on the use of high-speed steels.
· Steel (1.3343) is recommended for the manufacture of tools simple forms that do not require a large amount of grinding, for processing of conventional construction materials. (Cutters, milling cutters, reamers).
· To shaped and complex tools (threading and teeth), for which the main requirement is a high wear resistance, it is recommended to use a steel S18 is (tungsten).
· Cobalt high-speed steel (1.3243) is used for the machining of hard-corrosion-resistant and heat-resistant steels and alloys, interrupted cuts, vibrations, insufficient cooling.
· Vanadium high speed steels are recommended for manufacturing tools for finishing (broaches, reamers, shavers). They can be used for the treatment of hard materials when cutting chips of a small cross section.
· Tungsten-molybdenum steel (1.3343) is used for tools, working in roughing conditions, as well as for the manufacture of broaches, cutters, shaving cutters, milling cutters.
