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.
