Indexable Milling Bodies for CNC Machining
Indexable milling cutter bodies accept replaceable carbide inserts to perform face milling, shoulder milling, slot milling, and high-feed milling on CNC machining centres and milling machines. The cutter body is reused while only worn inserts are replaced, offering significant economic advantages in production milling operations compared to solid carbide end mills or brazed cutters. AIMS stocks indexable milling bodies and matching inserts from leading cutting tool brands across the full range of cutter types and diameters for industrial machining applications.
Face Milling Cutters
Face milling cutters are large-diameter shell mills used for efficient material removal from flat surfaces on horizontal and vertical machining centres. Multiple indexable inserts around the periphery allow high metal removal rates due to the combined cutting action of all inserts simultaneously. Insert pitch — the number of inserts per diameter — affects performance characteristics: close-pitch cutters with more inserts per diameter suit light depth, high-feed finishing operations, while coarse-pitch cutters with fewer inserts handle heavy roughing in difficult-to-machine materials like stainless steel, titanium, and hard cast iron where chip load management is critical.
Shoulder Milling Bodies
Shoulder milling bodies produce 90-degree shoulders in a single operation — milling both the floor of the step and the vertical wall simultaneously. True 90-degree wall angles depend on both the insert geometry and the cutter body's insert seating angle. Verifying the squareness specification for the specific tool body and insert combination is important when tight perpendicularity is required for subsequent assembly or sealing faces. Shoulder milling bodies are available in coarse pitch for roughing and fine pitch for semi-finishing and finishing operations where surface quality and dimensional accuracy take priority over metal removal rate.
High-Feed Milling Bodies
High-feed milling cutters use a small depth of cut combined with very high table feed rates to achieve exceptional metal removal rates, particularly in difficult materials like hardened steel, titanium, and superalloys. The high axial rake of the insert geometry directs cutting forces primarily axially into the spindle rather than radially, reducing bending load on the tool and allowing longer overhang toolholders to be used without chatter. High-feed milling is widely used in die and mould machining, aerospace component production, and heavy roughing in hardened materials where conventional end mills would struggle with tool life and vibration.
