Alumina Balls and Satellites. Union Process is the one source for 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90% or 99 ...
Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.
Milling Equations Machining Time : Peripheral Milling T m = L + A f r T m = Machining Time (Min.) L = Length of Cut A = Approach Distance f r = Feed Rate (Dist./ Min.) Machining Time : Face Milling T m = f r L + A + O T m = Machining Time (Min.) L = Length of Cut A = Approach Distance O = Cutter Run Out Distance f r = Feed Rate (Dist./ Min.) 4
Periphery Mill cutter can only be used for the Horizontal mill machine. 3. Side Milling Cutter: Side Mill cutter is a type of cutter in which the cutting teeth are present on the periphery and also at the face or end.

The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, this document will focus only on the vertical milling machine. A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.
Tips for Face Milling . First, take into account your tool stability and the horsepower in your spindle. With all those teeth and a smaller spindle, a million-tooth shell mill is going to get bogged down really fast. For Tormach machines, we recommend sticking to our shell mill if you’re going to be cutting things like steel.
Facemilling uses a lot of it with surprisingly low depth of cut because the cutter is so wide. A wide cutter relative to the workpiece produces a more pleasing finish (fewer “mow” bands), but too much horsepower can be injected into the cut and will lead to vibration problems.
