Feb 18, 2020 However, the smaller your end mill, the more fragile it gets, so if you try to cut through material too fast with a 1/16” end mill and you’re snapping it off into the workpiece. In most cases the most efficient use of a tool is to cut at around half of the diameter of the tool; with a ” tool, have a maximum depth of ⅛”.
maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree.crusher org fertilizer rock crushing products.

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 2 HRC according to Rockwell.
