采用下面几种铣削内球体的简便方法,可在X62W万能铣床或回转头立式铣床上铣出内球体。一、铣削原理将小于内球直径的一个圆柱体的端面,放在内球表面上,使其轴线与X-X线倾斜一个α角,并使圆柱端面圆与内球表面中心相切于P点,则此圆柱端面圆可与内球表面吻合(图1)。若视圆柱体端面为铣刀端面,内球体为分度头(或圆工作台)上的工件,在铣刀转动同时,转动分度头, With the following easy milling of the inner sphere, you can mill the inner sphere on a X62W universal milling machine or a rotary head vertical milling machine. First, the principle of milling will be less than the inner diameter of a cylinder end face, on the inner ball surface, so that its axis and XX line tilt an alpha angle, and the cylindrical surface of the inner circle and the center of the circle tangent to the point P, Then the cylindrical face of the circle with the inner ball surface match (Figure 1). If the cylinder end face milling cutter face, the ball for the indexing head (or round table) on the workpiece, turning the cutter at the same time, turn the indexing head,
