Get PriceJun 26, 2017 Step One: Calculate Your Effective Cutting Diameter. A ball nose end mill’s Effective Cutting Diameter (D eff) differs from its actual cutting diameter when utilizing an Axial Depth of Cut (ADOC) that is less than the full radius of the ball. Calculating the effective cutting diameter can be done using the chart below that represents some common tool diameters and ADOC combinations or by
Get PriceCobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as cast iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge

Get PriceBall milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by
