As highlighted in a comprehensive article by Market Prospects titled “What are a Milling Cutter and its Classification,” CNC machining stands as a cornerstone in modern subtractive manufacturing. This computer numerical control system brings efficiency and automation to the forefront, with CNC milling emerging as a key player in this realm. While CNC turning carves material away, CNC milling employs a rotary tool to achieve precision through material removal.
At the heart of CNC milling lies a variety of milling cutters, each tailored to specific applications. Let’s delve into some of the most common types:
End mills: Versatile and efficient, end mills boast flat bottoms and can cut axially and transversely, making them ideal for high-speed work.
Face milling cutter: Designed for plane cutting on large surfaces, face milling cutters sport replaceable carbide inserts, ensuring durability and quality.
Ball Knife: Also known as Ball Mills, these cutters feature hemispherical cutting tips, perfect for R angle and surface processing.
Slab mill milling cutter: While less common today, these tools are still used on manual milling machines for rapid surface machining.
Side cutter: Similar to end mills, side and face mills are versatile, although their popularity has diminished with advancing technologies.
Involute gear tool: Specialized tools for milling involute gears and designing gear and rack shapes.
Flying cutter: Offering functionality akin to face milling cutters, flying cutters are single-point rotary tools used on milling machines for large, flat surfaces.
Hollow sharpening: These cutters feed workpieces into the mill to produce cylindrical results, contrasting with face milling cutters.
Roughing end mills: With serrated teeth, roughing end mills expedite cutting and produce smaller metal pieces for easier cleanup.
Half-edge cutter: Ideal for crafting keyways in shafts, these cutters feature teeth perpendicular to the outside diameter.
Thread milling cutter: Utilized for producing threaded holes, thread milling cutters enhance stability and environmental adaptability during threading processes.
