The working principle of lathe is to use the rotary motion of workpiece and the linear feed motion of cutter to cut the workpiece.

Specifically, the working process of the lathe is as follows:

1. Workpiece installation: clamp the workpiece to be processed on the spindle of the lathe.

2. Tool installation: Select a suitable tool and install it on the tool rest of the lathe.

3. Start the lathe: make the spindle drive the workpiece to rotate.

4. Feed cutter: The cutter moves linearly along the axial or radial direction of the workpiece through the feed system of the lathe.

5. Cutting processing: the tool cuts on the rotating workpiece, thus realizing the processing of the workpiece.

Features of lathe working principle include:

1. High precision: the workpiece with high precision can be processed.

2. Diversified processing: various types of processing operations can be carried out.

3. Strong adaptability: suitable for various workpieces with different shapes and sizes.

When using a lathe, you need to pay attention to the following points:

1. Tool selection: Select the appropriate tool according to the processing requirements.

2. Setting of cutting parameters: Set cutting speed, feed rate and other parameters reasonably.

3. Workpiece clamping: ensure that the workpiece is firmly installed on the spindle to prevent loosening during machining.

4. Safe operation: Observe the safe operation rules of the lathe to avoid accidents.
