Unit 2: Speeds, Feeds, and Tapping

Feeds for end mills used in vertical milling machines range from .001 to .002 in. feed per tooth for very small diameter cutters on steel work material to .010 in. feed per tooth for large cutters in aluminum workpieces. Since the cutting speed for mild steel is 90, the RPM for a 3/8" high-speed, two flute end mill is

Mill (grinding)

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Basic End Mills Technical Information

A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations. The tooth design allows for little to no vibration, but leaves a rougher finish.

The Challenges of Machining Glass

Nov 22, 2013Ball end mills are typically used for surface profiling of G7 and G10, and the tool stepover used depends on the material and surface finish requirements. When a very smooth finish is needed, stepovers are generally in the 0.0005- to 0.001-inch range compared to 0.005 inch for applications in which surface finish isn't that critical.
