Types of CNC Inserts: A Comprehensive Guide to Cutting Tools

Introduction

In the world of precision machining, CNC (Computer Numerical Control) technology has revolutionized the manufacturing industry. With the help of CNC machines, complex parts and components can be fabricated with utmost accuracy and efficiency. Among the crucial elements of CNC machining are the cutting tools, which play a vital role in shaping and transforming raw materials. In this article, we will delve into various types of CNC inserts name that are commonly used in the machining process, exploring their unique features and applications.

1. Turning Inserts

Turning inserts are specifically designed for the turning process, one of the fundamental operations in CNC machining. These inserts are characterized by their geometry and cutting edge, which allow them to remove material from the workpiece efficiently. To optimize performance, turning inserts come in various shapes, including square, triangular, round, and diamond-shaped, commonly referred to as CNMG, TNMG, CCMT, and DNMG, respectively. Each shape corresponds to specific cutting applications, enabling machinists to achieve the desired precision and surface finish.

2. Milling Inserts

Milling operations involve cutting or shaping the workpiece using a rotating cutter. For this purpose, milling inserts are indispensable components in CNC machines. These inserts are manufactured with different cutting edge geometries to suit the varying requirements of milling processes. Square-shaped inserts, such as APKT, are ideal for general milling applications, while inserts with a high-positive edge, such as SEKN, excel in high-speed cutting. With the right milling insert, the machining process can be enhanced, resulting in superior precision and productivity.

3. Drilling Inserts

Drilling inserts primarily focus on creating holes in the workpiece. These inserts are designed to withstand the high forces generated during the drilling process and provide efficient chip evacuation to prevent built-up edge. Popular drilling inserts include SPMT, which features a sharp cutting edge suitable for drilling holes to tight tolerances, and CCMT, which excels in producing holes with good surface finish. With the right drilling insert, machinists can achieve precise and burr-free holes, improving the overall quality of the fabricated components.

4. Grooving Inserts

Grooving inserts, as the name suggests, are used for creating grooves or recesses in the workpiece. These inserts are available in different widths, depths, and designs to accommodate a wide range of groove sizes. Grooving inserts, such as MGMN, typically integrate chipbreakers to manage chip evacuation effectively, preventing tool damage and ensuring smooth machining operations. By utilizing the most suitable grooving insert, machinists can achieve precise grooves, such as those required in O-ring or snap ring grooves.

5. Threading Inserts

Threading refers to the process of producing helical grooves on the inside or outside surface of a cylindrical workpiece. Threading inserts are engineered to create precise and standardized threads, ensuring compatibility with other components. These inserts, such as 16ER, are available in various thread profiles, including metric, inch, and Whitworth, enabling machinists to meet specific threading requirements. Threading inserts play a crucial role in industries such as automotive, aerospace, and oil and gas, where threaded connections are ubiquitous.

Conclusion

In the realm of CNC machining, cutting tools are indispensable components for achieving precise shapes, dimensions, and surface finishes. With the right selection of CNC inserts, machinists can optimize the manufacturing process, enhancing productivity and quality. Turning inserts, milling inserts, drilling inserts, grooving inserts, and threading inserts all serve specific purposes, enabling machinists to meet diverse machining requirements. By leveraging the characteristics and unique features of these inserts, manufacturers can unleash the full potential of CNC machines, revolutionizing the way we produce intricate components.
