Milling is the machining process in which the removal of metal takes place due to the cutting action of a rotating milling cutter.. In a milling machine, the cutter is rotating due to this workpiece is fed against it.This can hold more than one tool at a time. The cutter rotates at a high speed and because of the many cutting edges, it removes metal at a very fast rate.

This types of drilling machine used to drill small holes at high speeds in lighter jobs or workpieces. The machine may be mounted on the bench or floor & the drilling work is started with the drill fed into the workpiece by purely hand control. Hand-feed permits the operator to sense the progress of the drill into the workpiece, so that if there is any drill worn out or jams it may be released

The drilling motion of the cable tool drilling machine must be synchronized with the gravity fall of the tools for effective penetration. Effective drilling action is obtained when the engine speed is synchronized with the fall of the tools and the stretch of the cable, while paying out the correct amount of cable to maintain proper feed of the bit. A shock absorber is installed at the crown

Rotary air blasting is a type of rotary drilling, where a blade bit or roller-cone bit is used to cut and break rock with a simple blade mounted on the end of a rotating drill stem. This stem is rotated while a thrust is applied to it by a pulldown mechanism that uses up to 65 percent of the weight of the machine. As the bit breaks and removes the rock using either a crushing and chipping
