1 Pc. Helical Brand New Made in USA 1/2" x 1-1/4" (LOC) 3FLT ZrN Coated Solid Carbide End Mill for Aluminum

    Applications:
  • Designed for roughing and finishing of aluminum and non-ferrous materials.
  • 35° helix allows for stronger corner design.
  • For slotting, peripheral milling, ramping, helical interpolation, and plunging.
  • Improved chatter free design, improved chip clearance, and higher feed rates.
  • High pressure coolant, flood, or mist is recommended.

    Coatings:
  • TiCN (H1) is a general purpose coating for non-ferrous materials.
  • ZrN (H2) for harder and more abrasive materials (recommended).

HIGH-SPEED MACHINING

AS IT APPLIES TO AEROSPACE TYPE ALUMINUM PARTS

    GOAL
  • Achieve the highest rates of material removal
  • Efficiently machine large, monolithic parts with multiple cavities and thin walls
  • Reduce the number of setups

MEANS
Use high-speed/high-velocity machining process

    REQUIREMENTS
  • High RPM/high feed rate capable CNC machining center
  • Reduced neck style high performance carbide end mills

    APPROACH
  • Machine at highest available RPM
  • Machine at high feed rates
  • Take axial cuts up to 20% of tools diameter
  • Take radial cuts up to full diameter of the tool
  • Leave at least 5% of tool diameter for the finish pass
  • This 5% will change depending on the thickness of the wall, feed rates, and desired finishes Machine in a “waterfall-like” manner (as shown in the example below)

EXAMPLE
Large part with 6 pockets milled to a .450 final “Z” depth, taking 3 passes at Z-.150 each.
