加工图1所示零件,在通常情况下,其难点在于:如何有效地控制各凹槽的等分精度和形位公差。即使用精密端齿通用转盘(单台)也难以达到有效控制加工质量目的,效率也难提高。为保证质量,提高效率,若将两台精密端齿通用转盘组合起来,如图2 Machining parts shown in Figure 1, under normal circumstances, the difficulty lies in: how to effectively control the groove of the bisecting accuracy and geometric tolerance. Even the use of precision gear universal turntable (single) is also difficult to achieve effective control of the quality of processing purposes, efficiency is difficult to improve. In order to ensure the quality and improve the efficiency, if the two precision end tooth universal turntable combination, as shown in Figure 2
