Lathe Machine Operation
• INTRODUCTION
• A lathe is a machine tool which turns cylindrical material, touches a cutting tool to it, and cuts the material.
• The lathe is one of the machine tools most well used by machining .

• As shown in Figure 2, a material is firmly fixed to the chuck of a lathe. The lathe is switched on and the chuck is rotated. And since the table which fixed the byte can be moved in the vertical direction, and the right-and-left direction by operating some handles shown in Fig. 3. It touches a byte's tip into the material by the operation, and make a mechanical part.

Three Important Elements
• Rotating Speed
• Cutting Depth
• Sending Speed (Feed)
• A beginner of a lathe must operate with low rotating speed, small cutting depth and low sending speed.
