A centre lathe is a machine used in engineering for machining materials. It performs operations like facing, cutting (a) screw(s), grinding, boring, and different turnings(Taper, Form, Plain). A centre lathe is a versatile machine in a workplace and ONLY a trained user should use it, as it can be very dangerous.

Center Lathe Parts
We all know that machines have different parts/tools that perform a certain job. This machine has the following parts, namely: Head stock, Carriage, Tail stock, Cross slide, Apron and Compound Slide.
- A Head stock is there to mount levers in order to be able to select and change gears.
- The Carriage has a saddle, apron, slide and used to provide cutting tools with a lever controlling its movement.
- Tail stock is used for tapered and gradually reducing materials.
- The cross slide makes it possible for the tool post and compound slide to move automatically or manually.
- An apron is fitted to the saddle. Its hand wheel is connected to a gear that meshes with a rack on a slide way.
- Compound Slide supports the tool post when clamping the cutting tool.
Center Lathe Chucks
A center lathe machine can have a three-jaw chuck or a four-jaw chuck. The four-jaw chuck moves independently and the three-jaw chuck moves dependently in a simultaneous way.
Advantages of a four-jaw chuck:
1. Used for large heavy work pieces
2. They provide accuracy and can do eccentric and concentric turning.
Its disadvantages are:
1. It is heavy or bulky.
2. It doesn’t self center and Precision setups are required.
Advantages of a three-jaw chuck are:
- Can auto center work pieces
- Precision work is guaranteed.
- It is not accurate when worn.
- It is are for light weight work pieces.
Center Lathe Beds And Their Uses
- A V-bed is used for precision work.
- A Flat-bed can provide support for heavy work.
- A V-flat bed is used for moderate heavy work and for accuracy.
Center Lathe Safety Precautions
As I mentioned above that a centre lathe machine can be dangerous! These precautions must be followed at all times to prevent injuries and so on.
- Make sure all guards are correctly fitted.
- Wear safety goggles and an apron(or PPE).
- Don’t wear loose clothing and/or jewellery.
- Never leave a key on the chuck.
- Press the emergency stop button when making adjustments.
- Check if there’s n oil or grease under the machine. Make sure it is in a working condition.
- Don’t allow another person to start the machine for you.
- Use the coolant to prevent the cutting tool from breaking and to reduce friction.
- Do not put tools on the lathe slide ways.
- Make sure you clean the machine after using it! And that it under goes its recommended maintenance.
Be on the lookout for more information, Cheers.
