Variables in Ball Mill Operation | Paul O. Abbe®

Ball milling is one of the few unit operation that improves with increasing mill diameter. If acceptable results can be obtained with a 12" jar mil, then good result will certainly be obtained with a 72" diameter mill.

Way to mount a fly cutter for a longitudinal feed?

A few possible kludges: 1) On a small horizontal mill, make up a fly cutter to fit the arbor. If the arbor is over, say, 1 3/4" diameter, make up a smaller arbor. This assumes the cross travel is enough to cut the cove in your part. 2) On a regular vertical mill with a tilting head, turn the head 90 degrees and insert an arbor with a fly cutter.

The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

A standard ball mill is 305 mm in internal diameter and 305 mm in internal length charged with 285 balls, as tabulated in Table 2.1. The lowest limit of the total mass of balls is 19.5 Kg. The mill is rotated at 70 rev/min.

Grinding Media - Growth Steel

In ball milling applications, the diameter of the balls, mill and throw action of the charge provides a low-impact environment– hence maximum abrasion resistance of steel balls is the desired characteristic. CHEMISTRY & HARDNESS High carbon content and high hardness levels affect abrasion resistance in steel balls.

Another way to approach this with a manual milling machine would be to use a ball end, end mill. Calculate the in-feed (down feed on the mill) at intervals and make multiple passes across the width of the aluminum. An end mill with a 1/2" ball radius and intervals of 1/4" should get it fine enough for a file to take out the waves in the cut.
