10 Turning Operations You Need To Know

Turning operations are a basic machining process used to shape and finish an object by removing material from its surface. Turning operations can be used to create a variety of shapes, sizes, and textures on a variety of materials. Knowing the basics of turning operations is essential for any machinist. Here are 10 turning operations you need to know.

1. Facing: Facing is a turning operation used to create a flat surface on a workpiece. It is typically used to create a flat surface perpendicular to the axis of rotation.

2. Turning: Turning is a turning operation used to create cylindrical shapes with a uniform diameter. Turning is often used to create shafts, pins, and other cylindrical parts.

3. Boring: Boring is a turning operation used to enlarge an existing hole. Boring is often used to create holes of a specific size and shape.

4. Knurling: Knurling is a turning operation used to create a pattern of ridges on a surface. It is typically used to create a grip on a part or to create a decorative pattern.

5. Threading: Threading is a turning operation used to create an internal or external thread. Threading is often used to create threaded fasteners such as bolts, screws, and nuts.

6. Reaming: Reaming is a turning operation used to create a uniform diameter in an existing hole. It is typically used to create a smooth and accurate finish in a previously drilled hole.

7. Drilling: Drilling is a turning operation used to create a cylindrical hole in a workpiece. It is often used to create fasteners or to create a through-hole for a shaft.

8. Tapping: Tapping is a turning operation used to create internal threads. Tapping is often used to create internal threads in a previously drilled hole.

9. Parting-off: Parting-off is a turning operation used to separate a workpiece from the stock material. It is typically used to create a finished part from a larger piece of material.

10. Broaching: Broaching is a turning operation used to create an irregular shape in a workpiece. It is often used to create keyways, splines, and other shapes.

Knowing these basic turning operations is essential for any machinist. It is important to understand how each operation works and when to use it in order to achieve the desired results.
