Different Types of Lathe Cutting Tools
Lathe cutting tools are essential for turning processes, and they are designed to remove material from a workpiece to create a finished product that meets the required specifications.
There are different types of lathe cutting tools available, each with its unique features and uses. In this article, we will explore the different types of lathe cutting tools in detail.
Turning Tools:
Turning tools are used to remove material from a workpiece to create a cylindrical shape. There are different types of turning tools available, each designed for specific turning operations. Some of the most common turning tools include:
Roughing Gouges:
Roughing gouges are used to remove large amounts of material quickly. They have a deep flute that allows for efficient chip removal.
Spindle Gouges:
Spindle gouges are used for more precise cuts and detailing. They have a shallower flute than roughing gouges, which makes them suitable for delicate work.
Bowl Gouges:
Bowl gouges are used to create concave shapes, such as bowls or vases. They have a deep flute that allows for efficient chip removal and a steep bevel angle that makes them suitable for creating smooth curves.
Skew Chisels:
Skew chisels are used to create a smooth surface finish on the workpiece. They have a flat cutting edge that allows for a clean cut.
Parting Tools:
Parting tools are used to cut a workpiece into two parts. They have a narrow blade that allows for precise cutting.
Boring Tools:
Boring tools are used to enlarge an existing hole or create a new hole with a precise diameter. They are available in different sizes and shapes, depending on the specific boring operation. Some of the most common boring tools include:
Straight Shank Boring Bars:
Straight shank boring bars are used for general boring operations. They have a straight shank that allows for easy tool change.
Taper Shank Boring Bars:
Taper shank boring bars are used for heavy-duty boring operations. They have a tapered shank that provides a secure grip and reduces vibration.
Internal Threading Tools:
Internal threading tools are used to create internal threads on a cylindrical surface. They are available in different sizes and shapes, depending on the specific threading operation.
Parting Tools:
Parting tools are used to cut a workpiece into two parts. They have a narrow blade that allows for precise cutting. Parting tools are available in different shapes and sizes, depending on the specific parting operation. Some of the most common parting tools include:
Straight Parting Tools:
Straight parting tools are used for general parting operations. They have a straight blade that allows for easy cutting.
Narrow Parting Tools:
Narrow parting tools are used for making narrow grooves or parting off small sections of a workpiece. They have a narrow blade that allows for precise cutting.
Diamond Parting Tools:
Diamond parting tools are used for making narrow grooves or parting off small sections of a workpiece. They have a diamond-shaped blade that provides a strong cutting edge.
Threading Tools:
Threading tools are used to create threads on a cylindrical surface. They are available in different sizes and shapes, depending on the specific threading operation. Threading tools are specific to either internal or external threads. Some of the most common threading tools include:
External Threading Tools:
External threading tools are used to create external threads on a cylindrical surface. They have a cutting edge that is shaped to match the desired thread profile.
Internal Threading Tools:
Internal threading tools are used to create internal threads on a cylindrical surface. They have a cutting edge that is shaped to match the desired thread profile and are available in different sizes and shapes, depending on the specific threading operation.
Grooving Tools:
Grooving tools are used to create grooves on a workpiece. They are available in different sizes and shapes, depending on the specific grooving operation. Grooving tools can be used for both internal and external grooving operations. Some of the most common grooving tools include:
Straight Grooving Tools:
Straight grooving tools are used for general grooving operations. They have a straight blade that allows for easy cutting.
Internal Grooving Tools:
Internal grooving tools are used for creating internal grooves on a cylindrical surface. They have a cutting edge that is shaped to match the desired groove profile.
External Grooving Tools:
External grooving tools are used for creating external grooves on a cylindrical surface. They have a cutting edge that is shaped to match the desired groove profile.
Facing Tools:
Facing tools are used to create a flat surface on the end of a cylindrical workpiece. They are available in different sizes and shapes, depending on the specific facing operation. Some of the most common facing tools include:
Lathe Faceplate:
A lathe faceplate is a large metal plate that attaches to the lathe spindle. It is used for facing operations on large workpieces.
Toolpost Mounted Facing Tool:
A tool post mounted facing tool is a small tool that attaches to the lathe tool post. It is used for facing operations on small workpieces.
Boring Head:
A boring head is a tool that can be used for both boring and facing operations. It is typically used for facing operations on irregularly shaped workpieces.
Advantages & Benefits of Lathe Cutting Tools
Lathe cutting tools offer several advantages and benefits that make them a preferred choice for machining operations. Let’s take a closer look at some of these advantages:
