Types of CNC Lathe Cutting Tools

Cutting tools for CNC lathes come in different types, and each type has its unique purpose. Below are some of the most common CNC Lathe cutting tools.

CNC Lathe Tools Materials

CNC lathe cutting tools

are usually made of several materials. Each of these materials has its strength. Thus, telling these materials helps users to select the right one(s) that will suit their work needs and requirements.

• High Speed Steel (HSS)

  High-speed steel (HSS) is used on lathes to make softer materials such as aluminum and steel. It is because at this point, they do not need to hold a very sharp edge. Also, it is used on lathes to make cuts that do not require much power. This material has the advantage of being more affordable than some high-tech materials, such as coated carbide. In addition, it is easier to sharpen whenever there is a need.

• Carbide

  Cutting tools made using carbide are very hard and can retain an edge for a long time. This property makes them ideal for machining hard materials like stainless steel and titanium. Tools with carbide tips are also very heat resistant, negating the need for a cool drink now and then. All these properties make carbide tools suitable for extended periods while handling difficult machining jobs. However, since carbide tools are generally harder, sharper, and more brittle, they will be more difficult to re-grind compared to HSS tools.

• Cobalt

  Cobalt tools are like carbide tools, but they work best when cutting at high temperatures. Cobalt is ideal for machining tough materials like stainless steel and inconel alloys. The material can withstand the heat generated in such operations while maintaining its hardness. Cobalt tools are normally used in situations where tools have to resist wear under extreme conditions.

• Ceramic

  Ceramic tools are usually referred to as "the heat resistors." They are very hard but fragile. So, they are good for production because tough materials like hardened steel get used to making these tools. They work best when applied in hard materials but do not stand up well when shock loads are applied. Also, it is worth confirming that they are not suitable for general use due to their brittleness.

• Indexed

  Indexed tools, which are often carbide-tipped tools that can be replaced in parts only - not the whole tool -, are often used by CNC lathes. These parts are economical in the long run. They are flexible and used for various materials. They also can be easily adapted for different operations by replacing only the cutting inserts.

Product Specifications and Features of CNC Lathe Cutting Tools

Key Features

• Material

  Cutting tools in CNC lathes are constructed of diverse materials to meet varying machining requirements. While high-speed steel (HSS) is preferred for general lathe applications, carbide tools are suitable for hard materials, and cobalt tools for high-temperature conditions. Ceramic and diamond coatings are added to enhance durability for precision.

• Tool Geometry

  Geometry of a tool, which include aspects such as the shape of the cutting edge, the relief angle, and the flank angle, defines the efficiency of the tool. Therefore, manufacturers consider the type of operation to be performed to define geometry. CNC lathes produce external and internal diameters; hence, the cutting tools must have diverse shapes and sizes. These shapes include tooling triangles for external work and cylindrical cutting edges for internal work.

• Tool Holders

  Tool holders are vital as they control the cutting tools. They ensure that cutting tools are securely fastened to allow for the production of accurate works. There are different types of tool holders, and they all differ in design. These holders are based on the demands of the CNC lathes. For example, the turret-type tool holders work on turret lathes, while the collet-style holders work on precision CNC lathes. One thing to note about these holders is that they must be compatible with the lathes the holders are intended to work with.

• Types of Lathe Cutting Tools

  Lathe cutting tools are of several types. Each of these varieties has an exclusive function. Below are some of the most popular kinds of cutting tools. They include:

  Turning Tools

  They remove material from workpieces to create cylindrical shapes. Thus, they are employed in operations such as external, internal, and taper turning. They, therefore, have a fundamental role in shaping workpieces to meet stipulated size and form standards.

• Facing Tools

  Facing tools have the role of creating flat surfaces on workpieces. They do it by eliminating material from the end of a workpiece. Thus, they are utilized in tasks that require formation of flat bases or faces on components. Basically, they are primarily utilized in forming surfaces that must be in contact with other components.

• Parting and Grooving Tools

  Parting and grooving tools cut narrow slots or grooves in workpieces. They either create specified shapes or remove parts of workpieces, like cutting off finished items. These tools are indispensable in operations that require notches, grooves, or part separation.

• Tread Cutting Tools

  Tread cutting tools create screws and bolts. Basically, they are utilized in the machining of helical grooves or ridges. This making them essential for producing fastening devices for use in multiple engineering and construction applications.

Also, have them professionally sharpened or follow DIY sharpening methods recommended by experts to maintain cutting edges.

• Tool Coating Inspection

  Cutting tools usually have coatings. These coatings are used for adding extra durability. Examine the lathe tooling cartridges for coating damage regularly. If there are signs of wear such as peeling or flaking, then it is time the coating is replaced. Coating damage affects cutting performance and leads to poor-quality machined products.

• Lubrication

  Ensure lathe cutters have proper lubrication before and after use. This reduces friction and heat. It, in turn, extends the life of the cutting tools. In addition, coolants and lubricants reduce the likelihood of material sticking to the tool, which causes wear faster. Above all, use the right type of coolant or lubricant for the material and tool.

• Repairing Chips and Cracks

  Tools may develop chips or cracks over time due to the materials being cut and wear caused by friction. Minor chips are fixable by professional tool services using welding or edge grinding techniques. However, you can’t repair a tool that has major breaking or cracks. Major repairs require replacement. Note that using chipped or cracked tools causes damage to the workpieces and can be unsafe to the operator.

• Storage Practices

  Store tools in protective cases or tool holders after use. Avoid storing them in a way where they have to come into contact with other tools, which might lead to nicks or scratches on the cutting edge. It also avoids possible brittleness due to breakage. Further, store them in a dry area where moisture can’t corrode the cutting edge or coating. Proper storage enhances their lifespan and acts as protection against wear.
