近年来,铝及铝合金已广泛应用于机械零件、模具等的制造上,使用量正在逐年增加。铝及铝合金具有重量轻、工艺性好、耐腐蚀、导热性好等优点,而且价格低廉;不过,由于铝太软,历来是立铣加工的难点。V·A·W公司,正是从这点考虑,首先推出了粗铣铝材的立铣刀。粗铣铝材的立铣刀具有如下特征: (1) 三条切削刃的前角均取15°;可大大改善切削性能,降低切削力。(2) 刀槽设计成螺旋形,不会因切屑堵
In recent years, aluminum and aluminum alloy have been widely used in the manufacture of mechanical parts, molds and the like, and their usage is increasing year by year. Aluminum and aluminum alloy with light weight, good technology, corrosion resistance, good thermal conductivity, etc., and low prices; However, due to aluminum is too soft, has always been the difficulty of vertical milling. V · A · W company, it is from this point of consideration, first introduced rough milling aluminum end mills. Roughing aluminum end mills have the following characteristics: (1) three cutting edges are taken 15 ° rake; can greatly improve the cutting performance and reduce cutting force. (2) Slot design spiral, will not be blocked by the chip
