Embodiment Construction
[0019] The method of high-frequency impact processing on the surface of bearing alloys is to fix the high-frequency impact processing head 3 on the tool bar 2 of the vertical lathe machine tool, and the bi-metal alloy to be processed uses tin-based Babbitt alloy as the friction-reducing layer (hardness HBa ≤0.1μm, surface microhardness increased by 20-40%.
[0020] The invention is a successful exploration for the inner and outer surfaces of the oil film bearing bushing of the bimetallic material with the bearing alloy with very low hardness (HB<24) as the anti-friction layer, and the superfinishing is carried out sequentially under one clamping. The brand-new processing method thus introduces a way of "cutting bends and straightening", which changes the traditional process route and process method, and has achieved remarkable results in reducing costs, improving efficiency, and improving performance.
