Description

technical field [0001] The invention relates to a ball-end milling cutter, in particular to a ball-end milling cutter with a multifunctional micro-woven structure in titanium alloy processing, and belongs to the field of mechanical processing. Background technique [0002] Titanium alloy has good corrosion resistance, toughness and heat resistance, so it is widely used in aerospace field. However, the unique characteristics of titanium alloys, such as: small thermal conductivity, small specific heat and active chemical properties, etc., have brought difficulties to its processing. The active chemical properties lead to high-temperature oxidation reaction of titanium alloy with air during processing, which reduces the plasticity of titanium alloy and increases its strength, so the cutting temperature is higher during processing. The small thermal conductivity and specific heat will lead to the inability to dissipate the cutting heat in time during the milling process, which ...
