• Description of workpiece processing工件加工的描述

(1) 将工件安装到专用夹头上Install the workpiece to the dedicated chucks;

(2) 将刀具安装到刀架上 Install the cutting tool to the tool holder;

(4) 打开冷却系统Open the cooling system;

(5) 在加工过程中，刀具进给由系统以一定角度旋转During machining, the tool feed is rotated by the system at a certain angle.

(6) Z轴进给系统驱动刀具进给Z axis feeding system drives the cutting tool to feed;

(7) 当加工到一定位置时，通过后驱动系统将刀具调整到一定高度When processing to a certain place, the cutting tool is adjusted to a certain height by the back-driving system;

(8) Z轴驱动系统驱动刀具后退，同时刀具随角度旋转，完成一个加工过程Z-axis driving system drives the cutting tool to back off, at the meantime, the cutting tool rotates with its angle, to complete a procession.

（9）切削刀具以其原始路线返回到工件的最前面，然后切削刀具旋转一定角度The cutting tool returns to the most front of the workpiece with its original route, then the cutting tool rotates a certain angle.

（10）重复步骤（5）-（9），完成工件的整个加工过程Repeat steps（5）--（9）, and finish the whole procession of the workpiece.
