Different Types of Lathe Cutting Tools for CNC Lathe Machines and Applications

CNC lathe machines have revolutionized manufacturing, offering precision and efficiency in creating complex parts. Central to the functionality of these machines are the cutting tools. Understanding the different types of lathe cutting tools and their applications is crucial for optimizing CNC lathe operations. In this article, we will explore the various types of cutting tools used in CNC lathe machines and their specific applications.

1. Turning Tools

a. Roughing Tools

Roughing tools are designed for removing large amounts of material quickly. They are used in the initial stages of the machining process to shape the workpiece roughly to the desired form.

b. Finishing Tools

Finishing tools are employed after roughing to achieve a smooth surface finish and precise dimensions. These tools ensure the final part meets the required specifications.

2. Boring Tools

Boring tools are used to enlarge existing holes or to achieve precise internal diameters. They are essential for creating accurate internal features in a workpiece.

a. Boring Bars

Boring bars hold the cutting inserts and can be adjusted for various diameters. They are versatile and used for both rough and finish boring operations.

3. Parting and Grooving Tools

a. Parting Tools

Parting tools are used to cut off (or part) a finished piece from the bar stock. They have a thin cutting edge to minimize material waste.

b. Grooving Tools

Grooving tools are used to cut grooves or recesses into the workpiece. These tools come in various shapes and sizes to accommodate different groove geometries.

4. Threading Tools

Threading tools are used to create internal or external threads on a workpiece. They are available in different profiles to match the thread standards required for the part.

a. Single-Point Threading Tools

Single-point threading tools are used for cutting threads with a single cutting edge. They are versatile and can create both internal and external threads.

b. Threading Inserts

Threading inserts are pre-formed with the desired thread profile. They are mounted on a tool holder and can quickly produce threads with high precision.

5. Drilling Tools

Drilling tools are used to create holes in a workpiece. In CNC lathe machines, drilling is often performed using a drill bit mounted in the turret.

a. Twist Drills

Twist drills are the most common type of drill bits. They are used for general-purpose drilling and come in various sizes.

b. Center Drills

Center drills are used to create a starting point for other drilling operations. They ensure the drill bit does not wander, resulting in more accurate holes.

6. Knurling Tools

Knurling tools are used to create a textured pattern on the surface of a workpiece. This pattern can improve grip or serve aesthetic purposes.

a. Axial Knurling Tools

Axial knurling tools create patterns parallel to the axis of the workpiece. They are typically used for creating straight knurl patterns.

b. Radial Knurling Tools

Radial knurling tools create patterns perpendicular to the axis of the workpiece, resulting in cross-hatch or diamond knurl patterns.
