Oxy-fuel cutting; the basics explained | HGG 3D Profiling
Oxy-fuel cutting: the basics. Before cutting, the cutting torch has to pre-heat the steel to ignition temperature at the starting point. At this temperature of around 960°C (depending on type of alloy), the steel has lost protective properties against oxygen and is still solid. Pure oxygen is then directed through the nozzle at the heated area.

GRINDING MACHINES - Carnegie Mellon University
Grinding wheels come in many different sizes, shapes, and abrasives (Figure 5-7). Some of the various types are listed below. Straight Straight wheels, numbers 1, 5, and 7, are commonly applied to internal, cylindrical, horizontal spindle, surface, tool, and offhand grinding and snagging. The recesses in type
Ball Mills - Mineral Processing & Metallurgy
The basic principle for rod grinding is reduction by line contact between rods extending the full length of the mill, resulting in selective grinding carried out on the largest particle sizes. This results in a minimum production of extreme fines or slimes and more effective grinding work as compared with a ball mill.
