Part 1 Common processing ifficulties of machining high manganese steel wear resistant casting
High manganese steel is a commonly used wear-resistant steel in machinery industry, these wear partsusually have excellent performance: high strength, high toughness,high wear resistance, but the machinability of high manganese steel is poor,it mainlyhas the following difficulties:
(1) Plastic deformation, severe processing har-dening;
(2) Large plasticity, easily to form BUE;
(3) Large cutting force, high toughness, not easy to break.
(4) Due to the large cutting force, the unit cutting power increases, the heat generated per unit time and high manganese steel itself poor thermal conductivity, the cutting zone temperature up to 1000 ℃, severe tool wear, tool life is low.
