CNC (Computer Numeric Control) machining has revolutionised the world of manufacturing, offering high levels of precision, efficiency, and repeatability. Integral to the success of CNC machining are the cutting tools used in the process. Each cutting tool has its unique characteristics and applications, making them suitable for specific machining tasks and materials. In this listicle, we will explore the top 10 cutting tools utilised in the world of CNC machining, delving deeper into their individual applications and the industries they serve best.
From router cutters & milling cutters to carbide drills, these cutting tools play a crucial role in shaping and creating components across a wide range of industries, including aerospace, automotive, and electronics. By understanding their uses and distinct features, you can make informed decisions when choosing the ideal cutting tools for your CNC machining projects, ensuring optimal productivity and impressive results.
1. End Mills
End mills are versatile cutting tools commonly used in milling operations. They are available in a variety of shapes and sizes, designed for cutting various materials and achieving different surface finishes. The two main types of end mills are flat (or square) end mills and ball end mills. Flat end mills produce clean, sharp edges and are used in operations such as slotting, profiling, and contouring, while ball end mills create rounded, smooth surfaces and are ideal for 3D contouring work. Industries that heavily utilise end mills include automotive, aerospace, and mould-making.
2. Face Mills
Face mills are another type of milling cutter designed to create flat surfaces on workpieces quickly. They consist of a large body with multiple carbide tipped cutting edges. Due to their design, face mills are capable of removing large amounts of material at a time, making them well-suited for facing and rough milling operations in industries such as heavy machinery and fabrication.
Drills are widely used in CNC machining for creating holes in workpieces. They come in various types, such as twist drills, carbide drills, and boring bits, depending on the required hole size, depth, and material type. Drills are used across all industries for producing holes in parts ranging from simple furniture fittings to complex aerospace components. For optimal drilling performance, it is essential to select the correct drill type for the material being machined, as this can greatly impact the tool life and hole accuracy.
Reamers are used in CNC machining to deliver high-precision, smooth holes with excellent dimensional accuracy. They follow the initial hole created by a drill and continue to remove small amounts of material, refining the hole’s internal surface. Reamers come in various types, such as hand reamers, machine reamers, and adjustable reamers, each suited for different applications and materials. Industries that require precise hole tolerances, like aerospace and precision engineering, often rely on reamers to achieve high-quality results.
Tapping is the process of cutting internal threads into a hole, and taps are the cutting tools used for this purpose. Available in a wide range of types, such as spiral flute taps, spiral point taps, and straight flute taps, they cater to various requirements and thread profiles. Tapping is a vital process in industries like automotive, construction, and electronics, where threaded holes are needed for fastening components with screws and bolts.
6. Thread Mills
Thread milling is an alternative to tapping for creating external and internal threads. Thread mills resemble end mills, with helical flutes designed to cut threads in a controlled, helical motion. Thread milling offers several advantages over tapping, such as better thread quality, the ability to mill various thread sizes with one tool, and increased tool life. Industries that demand high-precision threaded components, like aerospace, favour thread milling for achieving the desired results.
7. Chamfer Mills
Chamfering involves removing material from a workpiece’s edges to create a bevelled edge at a specific angle, usually 45 degrees. Chamfer mills are cutting tools designed explicitly for this purpose, resembling end mills with angled cutting edges. Chamfering operations improve part appearance and reduce sharp edges that may pose safety risks. Chamfering processes are commonly used in industries such as manufacturing and electronics, where components often require smooth, bevelled edges to prevent damage or injury.
