Horizontal vs Vertical Milling - The Differences Explained

28/04/2021  A vertical milling machine is the most commonly used type and features a vertically oriented cutting head or spindle. The spindle holds a rotating cutting tool against the workpiece. The spindle moves vertically, along the Y-axis. Other machine parts shift along the X-axis or even the Z-axis to position the workpiece correctly.

The Vertical Miller - DESIGN AND TECHNOLOGY

A vertical miller is used to shape metals such as mild steel and aluminium. It can also be used to shape plastics such as perspex and nylon. Full size milling machines such as the one shown below are powerful but also very accurate/precise. The cutting tools are very expensive and are broken easily if the machine operator tries to take too deep a cut, in one go. When using a vertical miller ...

Steel production environmental impact

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon ...
