用金刚石端铣刀高速加工铝材

试验用设计的金刚石端铣刀进行了铝合金铣削试验,在常规的切削速度下用普通刀具加工零件,由于积屑瘤和毛刺的形成,往往引起刀具寿命短,加工表面质量差及切削刃质量差.在许多行业的铝合金加工技术中,较高的表面光洁度及切削刃质量很重要,也很需要.本试验的结果揭示出使用新设计的金刚石端铣刀高速切削铝合金,能加工出镜面表面,而不产生积屑瘤和毛刺.

High-speed Machining of Aluminium Using Diamond Endmills

Milling experiments on aluminum alloy were carried out using a laboratory-designed diamond endmill. The machining of aluminium alloy using a conventional tool at a conventional cutting speed generally results in short tool-life, poor surface quality and poor edge finishes because of the formation of built-up edges and burrs. The machining technology of aluminum alloy surfaces with a good surface finish and edge finishing is very important and required in many industries. The experimental results reveal the possibility of machining a mirror-like aluminum alloy without built-up edges and burrs using the designed diamond endmill at high speed.
