Die Milling APMT Tungsten Carbide Inserts For Metal Machining Metal Working

Carbide Tooling Inserts Die Milling APMT For Metal Machining Metal Working


Application:

For Roughing, use a tough coated insert grade with a large nose radius, heavy honed cutting edge and large chipbreaker. Cut at a low SFM with a large Depth of Cut (ap) and high Feed Rate per Rev. (fn)
For Universal, use a hard, tough & wear resistant coated insert grade with a medium nose radius, honed cutting edge and medium chipbreaker. Cut at a medium SFM with a medium Depth of Cut (ap) and medium Feed Rate per Rev. (fn)
For Finishing, use a hard & wear resistant coated insert grade with a small nose radius, sharp to light honed cutting edge and small chipbreaker. Cut at a high SFM with a medium Depth of Cut (ap) and medium Feed Rate per Rev. (fn)

Optimum: Insert Wear, decrease Spindle Speed (n) and/or increase Feed (fn) or change to a harder insert grade. Insert Chipping, increase Spindle Speed (n), decrease Feed (fn), and/or change to a heavier honed edge or change to a tougher insert grade.

Coolant: Use Coolant, if the insert grade allows, and always use high pressure coolant to remove the hot chips and heat from the insert to reduce thermal shock


1. Substrate - The alloy carbide's properties, grain size, and cobalt content.
2. Geometry - The physical characteristics of an insert that differentiates one shape from the next.
3. Tolerances - The allowed deviation of all insert dimensions.
4. Relief Angle - The angle measured from the vertical line perpendicular to the cutting edge of the insert and the cutting face of the insert.
5. Rake Angle - The angle formed on the insert from the top surface area and the bottom of the insert chip flow area when parallel to the floor. 6. Chipbreaker - The formed groove or recess along the cutting edge of the insert that breaks chips into small manageable lengths.
7. Edge Preperation - The process used to prepare the insert's edge cutting condition for specific application and material. Achieved by honing, chamfering, "T" land or any combination there of.
8. Coating - Thin layer of titanium nitrade on the surface of the insert that allows for greater cutting speeds, wear resistance and longer insert life.
9. Grade - A combination of substrate and coating that determines the hardness and toughness of the insert.
