CNC数控加工中心

在加工中心上加工零件的特点是：被加工零件经过一次装夹后，数控系统能控制机床按不同的工序自动选择和更换刀具；自动改变机床主轴转速、进给量和刀具相对工件的运动轨迹及其它辅助功能，连续地对工件各加工面自动地进行钻孔、锪孔、铰孔、镗孔、攻螺纹、铣削等多工序加工。由于加工中心能集中地、自动地完成多种工序，避免了人为的操作误差、减少了工件装夹、测量和机床的调整时间及工件周转、搬运和存放时间，大大提高了加工效率和加工精度，所以具有良好的经济效益。

What is CNC ?

Computer Numerical Control (CNC) machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.

When a CNC system is activated, the desired cuts are programmed into the software and dictated to corresponding tools and machinery, which carry out the dimensional tasks as specified, much like a robot. In CNC programming, the code generator within the numerical system will often assume mechanisms are flawless, despite the possibility of errors, which is greater whenever a CNC machine is directed to cut in more than one direction simultaneously.
