Introduction to Machining: Milling Machine

• The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines, shown is the vertical milling machine. • A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece.

Rolling of Metals: Process and Principles (With Diagram)

Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.

Difference Between Sag Mill vs Ball Mill

 · The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue.

Types of Bearings

 · In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly.But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the ...
