In the present study, we systematically investigated the effect of mechanical milling on the magnetic properties of SmFeN x powders produced by the reduction-diffusion process. The Sm-Fe powders obtained by the reduction-diffusion process were composed of an SmFe single phase. After nitrogenation, the coercivity and saturation magnetization of the powders were 0.48 kOe and 13.32 ...

This type of lathe can handle workpieces up to 25 inches in diameter and up to 200 inches long. However, the general size is about
Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many ...
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. This cutter is mostly used in straddle Milling operations and face Milling operation.

Lathe is defined as the machine tool used to rotate the work piece to perform various operations like turning, facing, knurling, grooving etc.Main function of lathe is to remove excess material from work piece to give it the desired shape. In a lathe machine, the work piece is rotated against tool which is used to remove the excess material.
The by-products in rice milling are rice hull, rice germ and bran layers, and fine brokens. V. MILLING SYSTEMS A rice milling system can be a simple one or two step process, or a multi stage process. In a one step milling process, husk and bran removal are done in one pass and milled or white rice is produced directly out of paddy.
