摘要
镍基合金材料在600℃以上高温中具有高强度,抗氧化性及耐腐蚀性的优良性能,常常用于航空,核电等重要领域。在对其切削加工时,一般采用冷风切削技术。也就是在对镍基高温合金材料等类似工件材料切削时,使用-30℃-60℃的低温冷风喷射到切削区,同时使用微量的植物油代替润滑剂,达到控制高速切削时切削区温度的目的,从而有效减小刀具刃的磨损,进而减少表面粗糙度。本文阐述通过设置不同的切削实验条件,对高温合金材料进行高速切削,分析不同条件下刀具刃磨损情况,并就刀具磨损的深浅程度对加工件表面粗糙度的不同影响进行分析。
the nickel-based alloy materials in 600℃ high temperature above has high strength,oxidation resistance and corrosion resistance of good performance,often used in aviation,nuclear power,and other important fields.In the cutting processing time, generally USES the cold wind cutting technology.Also is to hi-based high-temperature alloy materials and similar workpiece material cutting , use-30℃-60 ℃ low--temperature air cooling jet to cutting area,at ,the same time Use the traces of the vegetable oil instead of lubricant,achieve control of high speed catting when the temperature of cutting zone of the purpose,thus reduce the cutting tool wear of the blade,and reduce the surface roughness.This paper through the set up different cutting experiment conditions,high temperature alloy materials of high speed cutting,analyzes different conditions tool wear blade,and the depth of the tool wear degree of product surface roughness affect different analysis.
