球头立铣刀的球面前角、球面后角的加工比较复杂,据有关资料介绍,一般在专用的精密工具磨床上进行磨削。在没有专用的工具磨床的情况下,我们利用日本C—40工具磨的半径磨削附件和钻尖磨削附件,在C—40工具磨床上完成了球头立铣刀球头部份的刃磨加工,加工顺序为:①球面前角;②球面一次后角;③球面二次后角;④球面铲背角。1、球面前角的磨削利用C—40日本工具磨床的半径磨削附件
Ball-end milling the ball rake angle, the spherical posterior corner of the processing more complicated, according to the information, usually in a dedicated precision tool grinding on the grinder. In the absence of a special tool grinder, we use the C-40 tool grinding radius grinding attachment and the drill point grinding attachment, the ball end mills in the C-40 tool grinder completed the blade Grinding processing, processing order: ① spherical front; ② a posterior horn of the ball; ③ spherical second posterior; ④ spherical shovel back angle. 1, the grinding of the spherical anterior horn using C-40 Japan Engineering durable count of the first half mirror
