Kennametal has introduced an expansion to the HARVI™ I TE series, the HARVI I TE four-flute ball nose end mill. Designed for highly productive 3D roughing and finishing operations, it delivers lower machining cost through maximum metal removal in a broad range of materials.
Anatomy of a high performer
The HARVI I TE ball nose end mill features an innovative proprietary relief that requires a closer look. In the most critical area – the ball nose section – a wavy contour shapes the rippled relief which provides improved coolant flow into the cutting zone.
Maximum productivity, maximum tool life in 3D milling operations: The HARVI I TE four-flute ball nose end mill with the rippled relief in the ball nose section.
The rippled relief enables higher feeds and speeds as well as increased depth of cuts by advanced vibration damping and lower cutting forces.
On the outer diameter, the relief changes its shape, and turns into the eccentric faceted relief. The eccentric faceted relief provides exceptional edge strength, geometric accuracy, lower cutting forces and makes this end mill series very versatile.
Other geometry advancements of the square end styles —including a twisted end face, chip gashing, and a variable helix angle—have also been engineered into this new solid carbide end mill.
Nice blog.These Ball Nose End Mills are basically used for drilling shallow holes and used multidimensional contours in mold or die. there are a wide range and shapes of ball end mills.
