我厂将一台C620车床改为电气插销板程控车床。设计时,考虑四方刀架刀位不足,不能满足一道工序所需刀具的要求。若采用六方刀架,感到操作不便,而且刀具转位半径大,刚性也差。因此,我们除将原结构的四方刀架改为自动转位刀架外,又将尾顶尖改为自动转位的四刀位尾刀架,结构简单,使用方便。 I plant will be a C620 lathe to electrical latch plate program-controlled lathes. Design, consider the lack of four knife holder position, can not meet the requirements of a process tool required. If the hexagonal knife holder, feel inconvenient to operate, and the tool indexing radius, rigidity is poor. Therefore, in addition to the original structure of the four-way turret into automatic turret, but also the tail tip to automatically indexing four-knife tail knife holder, the structure is simple and easy to use.
