In today's booming development of machining centers,the importance of their core component,the CNC turntable,is increasingly prominent.Based on this,this article classifies the commonly used products of CNC turntables in machining centers,points out common application scenarios,and provides an overall introduction to the structure and key technologies of CNC turntables.I hope it can help designers and users of CNC turntables clarify their thinking and provide reference for the development technology path of CNC turntables.
