Ball End Mills
HTPM series milling cutters have unequal flute spacing (variable pitch) and multiple helix angles (35° and 37°) to reduce chatter and harmonics, for improved stability and better finishing. This also optimizes chip formation and chip evacuation. These 4-flute end mills feature a spherical ball end. Aluminum Chromium Nitride (Hybrid AlCrN) coating …
Optimize Depth of Cut and Stepover for Better CNC Milling
Increasing Depth of Cut or Stepover may require you to do a better job chip clearing. That can mean such things as: Aiming the coolant nozzle better to clear chips from the cut. Increasing your coolant pressure or if you use mist increasing the air pressure. Switching from mist to flood coolant.
Ball Nose Milling Strategy Guide
Ball Nose Milling Without a Tilt Angle. Ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.To properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish, follow the 2-step process below (see Figure 1).
CNC basics
Flutes. This is arguably the most important feature to consider when choosing an end mill for CNC machined aluminum. Again, aluminum is gummy and soft, which means it tends to stick in the flutes of your CNC mill. While coatings can help alleviate this issue, if you're using a 4- or 5-flute end mill to cut aluminum, even the best coatings may ...

Optimal tool orientation control for 5-axis CNC milling with ball-end …
When a ball-end milling tool cuts a given path on a smooth surface, it is desirable to maintain a fixed angle ψ between the tool axis a and the local surface normal n at each point, to ensure a constant speed of the tool cutting edge against the surface. This means that the tool axis a must lie on a cone of angle ψ about the surface normal n at …
Flute Count Matters [End Mill Performance]
Flute Count Basics. Flute count is a term that describes the number of cutting edges on an end mill, such as four flute mills. The general rule is to use 4 flutes for machining steel and harder alloys, as they have smaller flute valleys, which provide less chip evacuation. On the other hand, 2 flutes are commonly used for machining aluminum …
