The Difference Between ISO Turning Inserts and Non-ISO Inserts

Inserts are an integral part of modern CNC turning operations, providing versatility and efficiency to machine tools. When selecting turning inserts, it is essential to understand the difference between ISO turning inserts and non-ISO inserts. This knowledge can significantly impact the performance, cost, and ease of use of your machining operations.

What are Inserts?

Inserts are replaceable cutting tools that are mounted to a machine's tool holder. They are designed to cut a variety of materials, including metals, plastics, and composites. Inserts come in various shapes, sizes, and materials, and they can be used to perform different cutting operations, such as turning, grooving, and facing.

ISO Turning Inserts

ISO turning inserts are named after the International Organization for Standardization (ISO), which establishes a standard system for designating insert shapes. ISO inserts are identified by a letter code (e.g., TN, TF, TNM) followed by a number (e.g., 300, 1000, 040). This standardization makes it easy to identify and compare inserts from different manufacturers.

• Standardization: The ISO system provides a clear and consistent way to identify insert shapes and sizes, making it easier to select the correct insert for a given application.
• Interchangeability: ISO inserts are designed to be easily swapped out, which saves time and reduces downtime.
• Compatibility: ISO inserts can often be used in a variety of machines and tool holders, which increases their versatility.

Non-ISO Turning Inserts

Non-ISO inserts refer to inserts that do not follow the ISO standard. These inserts may have their own unique numbering or Coated Insert naming conventions, which can make it difficult to identify and compare them to ISO inserts.

• Non-standardized Design: The lack of a standardized design can make it challenging to determine the best insert for a specific application.
• Non-interchangeability: Non-ISO inserts may not be compatible with certain machines or tool holders, which can limit their use.
• Lack of Compatibility: The unique design of non-ISO inserts can make it difficult to find replacement inserts if the original inserts become worn or damaged.

Choosing the Right Inserts

When selecting turning inserts, it is crucial to consider the following factors:

• Material: The insert material should be appropriate for the material being machined.

• Shape: The insert shape should match the cutting operation and workpiece geometry.
• Coating: A coating can improve the insert's wear resistance and thermal stability.

Conclusion

ISO turning inserts offer standardized design, interchangeability, and compatibility, making them a popular choice for many CNC turning operations. Non-ISO inserts, while sometimes available, may lack these benefits. When choosing turning inserts, it is essential to consider the specific requirements of your application and select the inserts that will provide the best performance, cost-effectiveness, and ease of use.
