Ultra-cold treatment is after material heat treatment, the only can be used in tool, cutter and spare part processing technology, can stable material size precision, improve material wear-resisting property, and recovery material mechanical property.
Ultra-cold treatment on the material treatment not only limited material surface treatment, but also penetration in material internal organization, reflects the overall effect, especially for the regrinding of cutting tool, does not affect the organizational structure, can use repeatedly. Ultra-cold treatment technology not only can effectively reduce the work piece quenching stress, but also can increase the size of stable performance.
Because of these characteristics and advantages, ultra-cold treatment technology in precision stamping die, nanometer material, precision plastic cement mould, cutting tool, hobbing cutter, high speed steel material, cemented carbide material, aluminum alloy material, powder metallurgy mold and other industries widely used.
For example cemented carbide, in the process of ultra-cold treatment, can effectively adjust the internal stress of cemented carbide, reduce the tensile stress produced by the cobalt, enhance produce the resistance of micro crack, effectively reduce micro crack produce, so as to improve the fatigue strength resistance, toughness, in the meantime effectively reduce the carbide strip and wear-resisting performance is obviously improved.
