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 .

• Carriage

• Dead Center

• Clutch

• Longitudinal & Transverse Feed Control

• Cross Slide

• 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.

Drilling

• Drilling allows a person to make holes through boards, metals, and other materials.

Boring

• Boring is an operation to enlarge and finish holes accurately. This may be done on a lathe or a milling machine.

Tapping

• Tapping is the process of cutting a thread inside a hole so that a cap screw or bolt can be threaded into the hole. Also, it is used to make threads on nuts.

Turning

• Turning is a lathe operation in which the cutting tool removes metal from the outside diameter of a workpiece.

Threading

• Single point threading is a lathe operation used for creating internal / external precision machined threads with a single point tool.

Knurling

• Griping the piece of any metal is calleed knurling

Facing

• Facing is a lathe operation in which the cutting tool removes metal from the end of the workpiece or a shoulder.

Drill Press

• A machine designed to hold drill bits which will produce cylindrical holes.

Broaching

• Broaching is an operation that completes the cutting in one stroke or cut.
