廿、分度头有几种,它的主要功能有哪些?分度头是铣床上的重要附件,有时在钳工划线或其它机床上,也能用它分度。分度头有简单分度头、万能分度头和自动分度头几种,其中最常用的是万能分度头,如FW 200、FW 250、FW 270、FW 320等。分度头的功用主要有:能将工件以本身轴线为旋轴中线作各种不同的等分;能将工件的本身轴线和铣床工作台平面装成水平、倾斜和垂直各种不同的夹角;利用挂轮可使工件随工作台的移动作连续旋转,铣螺旋槽或凸轮。
20, there are several indexing head, what are its main functions? Indexing head is an important attachment on the milling machine, and sometimes in the fitter scribing or other machine tools, can also use it indexing. Indexing head has a simple indexing head, universal indexing head and automatic indexing head several, the most commonly used universal indexing head, such as FW 200, FW 250, FW 270, FW 320 and so on. The function of indexing head are: the workpiece to its own axis as the axis of rotation for a variety of different points; can be the workpiece itself and the milling table axis plane installed horizontal, inclined and vertical different angles ; Use of the wheel can make the workpiece with the work table for continuous rotation, milling spiral groove or cam.
