A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.
Explanation: A quick return mechanism converts the circular motion into reciprocating motion (repetitive back and forth linear motion).; This mechanism is mostly used in shaping, planning, and slotting machines.; In a slotting, the rotary motion of the drive is converted into reciprocating motion of the ram by the mechanism housed within the column or the …

A quick return motion mechanism is used in the shaper and slotter machine in which the circular motion is converted into reciprocating motion so that the slider moves forward and backwards. In the forward direction, the cutting process occurs while in return there is no such cutting.
The drilling machine part carries the drill head and the housing containing the driving mechanism. This material is also made of the same material like the base, making it to have rigid structure. Some manufacturer of some drilling machine provides a guideway so the drill head can slide over the upper arm.
