This insert has an advanced hard coating made with nano technology, and superior deformation resistance and toughness with engineered carbide substrate. It is an excellent choice for medium machining of a wide variety of workpiece materials, particularly stainless steels and high-temperature alloys.
With the use of traditional milling cutters, the lead angle dictates the kind of cutting force produced.when the lead angle (r) increases, the radial forces (fr) decrease and the axial forces (fa) increase, changing the resultant cutting force direction (R). At a 45-degree lead angle, the fr and fa are balanced. Which lead angle is best will depend on fixturing, part shape and size, workpiece material, machine power and type, and gage line or overhang.
When the tool is used at different depths of cut (aa), the lead angle changes. The lead angle can be measured at the depth-of-cut line; however, the effective lead angle will change throughout the cutting depth. In Figures 3A, 3B and 3C, a 3/4-inch diameter (inscribed circle) insert is shown at a depth of cut of 0.375, 0.250 and 0.125 inch respectively. See first picture.
As the lead angle changes, the cutting forces are also changing. In Figure 3A where the insert is at the maximum depth of cut (one half the insert IC), the axial and radial forces are balanced. When the depth of cut is reduced, the radial forces decrease and the axial forces increase. At a very light depth of cut, the forces would be almost totally in the axial direction. Thus, depending on the setup and part parameters, maximum productivity can be gained with a round insert cutter by selecting the optimum depth of cut that best controls the cutting forces.
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.
