SEKT1204 AFFN-NL YD101 Carbide Milling Inserts for Aluminium Machining
Description:
Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on 45steel, cast iron, nonferrous materials, plastics and other tough-to-machine materials.
| Product features - Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems
- Multi Layer coating TiC/Al2O3/TiN
- Good toughness, high strength in use and versatility for roughing, medium roughing of steel, alloy steel and cast-iron, especially for high speed and quick cutting
- Use for slotting and slab or straddle milling

Application:
The shape of an insert has a major influence on the impact resistance of the carbide. The weakest section of a milling insert is the corner, which is exposed to constant interrupted cuts and extreme heat changes. Since a round insert has no corners, it is more secure than any other shape.
Consider the tremendous forces that are placed on a milling insert in a typical cut. As the insert enters the cut, it is subjected to a large compressive load. The initial contact between the cutting edge and the workpiece may be very unfavorable depending on the position of the cutter in relation to the workpiece. As the insert moves through the cut, the chip thickness is constantly changing, varying the radial and axial cutting forces. Finally, as the insert leaves the workpiece, it is subjected to tensile stresses that break down the carbide. The chip bending away from the insert places large tensile or "ripping" stress on the face of the carbide.
In addition to normal milling operations, there are certain applications that are particularly damaging to carbide. Here are some of the most difficult jobs that demand a lot of strength from the shape of the insert:
- Milling of castings, where the axial depth often varies throughout the cut,
- Workpieces with hard spots or inclusions that cause unpredictable insert life,
- Raw materials that are flame or plasma cut, leaving very hard surfaces to machine,
- Forgings or castings with slag or scale on the surface that can result in the notching of the insert,
- Hardened steels, tool steels and cast irons, and
- Heat resistant materials like Inconel, titanium and Hastelloy.
