用轻金属或夹布胶木等材料加工球形零件时,一般都是用管子状的刀具进行加工(图1)。但是,在其它像钢、铁等材料上加工球面时,就不能采用管子形刀具,而可以按照同一原理制成图2形状的铣削头来加工球面。结构原理及其使用铣削头结构比较简单,它通过电动机(0.4千瓦、1440转/分)驱动旋转。工件一端卡在三爪卡盘上,另一端由活顶尖顶住。工件与铣刀头旋转方向相反。铣头轴线与刀头切
When machining spherical parts with materials such as light metal or cloth and bakelite, pipe-shaped tools are typically used for machining (Figure 1). However, when machining spherical surfaces on other materials such as steel and iron, it is not possible to use pipe-shaped tools. Instead, a milling head of the shape shown in FIG. 2 can be formed by the same principle to machine the spherical surface. Structure principle and its use Milling head structure is relatively simple, it is through the motor (0.4 kW, 1440 r / min) to drive rotation. One end of the workpiece stuck in the three-jaw chuck, the other end by the living roof to withstand. Workpiece and milling head rotate in the opposite direction. Milling head axis and cutter cut
