数控铣床主传动系统的设计含7张CAD图+说明书

数控铣床主传动A0

数控机床是装有程序控制系统的机床。该系统能够逻辑地处理具有使用号码，或其他符号编码指令规定的程序。数控机床是以数控技术为代表的新技术对传统制造产业的渗透形成的机电一体化产品，起技术范围覆盖很多领域：（1）机械制造技术（2）信息处理、加工、传输技术；（3）自动控制技术；（4）伺服驱动技术；（5）传感技术；(6软件技术等。计算机对传统机械业的渗透，完全改变了制造业。制造业不但成为工业化的象征，而且由于信息技术的渗透，使制造业犹如朝阳产业，具有广阔的发展天地。数控机床就是将加工过程所需的各种步骤以及刀具与工件之间的相对位移量都是用数字化的代码来表示。通过控制介质数字信息送入专用区域通用的计算机。计算机对输入的信息进行处理，发出各种指令来控制机床的伺服系统或其他执行元件，使机床自动加工出所需要的工件。
