Turning and milling of CNC lathes are two common metal cutting methods, which achieve efficient and high-precision processing on CNC lathes through precise programming and control.

1. Turning:

Turning is one of the most basic processing methods of CNC lathes. CNC lathes are usually used to process shafts, discs, sleeves and other workpieces with rotating surfaces. During the turning process of CNC lathes, the workpiece is rotated by the spindle drive, and the cutting tool moves linearly or curvilinearly along the axis of the workpiece, thereby removing excess metal material on the workpiece to form the required shape and size. Turning of CNC lathes can achieve a variety of different cutting methods, such as external turning, internal turning, end turning, grooving, cutting, etc.

2. Milling:

Milling is another important processing method in CNC lathes. Unlike turning, milling is usually used to process workpieces with complex shapes such as planes, curved surfaces, grooves, etc. During the milling process of a CNC lathe, the workpiece is usually fixed on the workbench, and the milling cutter is rotated by the spindle drive and moves in a straight line or curve along the surface of the workpiece, thereby removing the excess metal material on the workpiece. The milling process of a CNC lathe can achieve a variety of different milling methods, such as plane milling, surface milling, groove milling, contour milling, etc.

The turning and milling processes of CNC lathes have many advantages:

1. High precision: CNC lathes are programmed and controlled by computer control systems, which can achieve accurate processing trajectories and cutting parameter settings, thereby obtaining high-precision processing results.

2. High efficiency: CNC lathes can automatically complete the processing process without manual intervention, thereby greatly improving processing efficiency.

3. Strong flexibility: CNC lathes can process workpieces of various shapes and sizes, and are suitable for processing needs in different industries and fields.

4.Programmability: The processing program of CNC lathes can be programmed and modified by computers, which is convenient and fast, and easy to save and copy.

It should be noted that when performing turning and milling on CNC lathes, it is necessary to select appropriate cutting tools, cutting parameters and processing technology to ensure processing quality and efficiency. At the same time, the machine tool needs to be regularly maintained and serviced to ensure the stability and reliability of the machine tool.
