Understanding the ISO Designation of Chip Breaker Inserts

Understanding the ISO Designation of Chip Breaker Inserts

Chip Breaker Inserts are essential components in the tooling industry, especially in the realm of machining operations. They Iscar Inserts are designed to manage chip formation and flow, which directly impacts the efficiency and quality of the cutting process. The ISO (International Organization for Standardization) designation system is widely used to classify and specify these inserts. This article aims to provide a comprehensive understanding of the ISO designation system for chip breaker inserts.

What is a Chip Breaker Insert?

A chip breaker insert is a cutting tool insert that is specifically designed to control the formation, flow, and evacuation of chips during the cutting process. It is an integral part of the cutting tool, working in conjunction with the cutting edge to ensure smooth and efficient chip evacuation. Proper chip control is crucial for maintaining tool life, reducing vibrations, and improving surface finish.

ISO Designation System

The ISO system provides a standardized method for identifying and specifying chip breaker inserts. This system is based on several key parameters, which include:

• Material Type: The type of material the insert is made from, such as high-speed steel (HSS), ceramic, or carbide.

• Edge Geometry: The geometry of the cutting edge, such as positive or negative rake angles, and the type of insert, such as insert with a flat cutting edge or insert with a chamfered cutting edge.

• Insert Shape: The shape of the insert, such as triangular, square, or round.

• Insert Size: The size of the insert, which is typically specified by its thickness, width, and length.

• Chip Breaker Features: Specific features that control chip formation and flow, such as chipbreakers, chip dividers, or chipbreakers with special profiles.

Example of an ISO Designation

An example of an ISO designation for a chip breaker insert could be: "K20.1010.040". Let's break down this code:

• K: Indicates the material type, in this case, it is a carbide insert.

• 20: Represents the edge geometry, which could be a specific angle or profile.

• 1010: Denotes the insert shape, in this case, a square insert.

• 040: Specifies the insert size, with 040 indicating a particular thickness, width, and length combination.

• Additional characters: These may indicate specific chipbreaker features or other details about the insert.

Benefits of ISO Designation

The ISO designation system offers several benefits for both manufacturers and users of chip breaker inserts:

• Standardization: Ensures consistency in the manufacturing and supply of chip breaker inserts, facilitating easier part integration and reduced errors.

• Communication: Provides a clear and concise way to communicate insert specifications between manufacturers, suppliers, and users.

• Cost Efficiency: Allows for the comparison of different inserts based on their performance, leading to cost savings and improved efficiency.

Conclusion

Understanding the ISO designation of chip breaker inserts is vital for anyone involved in the tooling and machining industries. This standardized system simplifies the selection and communication of insert specifications, leading to improved performance, reduced costs, and enhanced part quality. By familiarizing oneself with the ISO designation system, users can make informed decisions when selecting Sumitomo Inserts the right chip breaker insert for their specific application.
