A shaper machine is machine tool that uses reciprocating straight line motion of the tool and a perpendicular feed of the job or the tool.In a shaper rotary movement of the drive is converted into reciprocating movement by the mechanism contained within the column or frame of the machine. The ram holding the tool gets the reciprocating movement.
In a standard shaper metal is removed in the forward cutting stroke, while the return stroke goes idle and no metal is removed during this period. This mechanism is known as quick return mechanism.
Parts Of Shaper Machine-
It is the main body of the machine. It consists all element of the machine. It works as pillar for other parts. Base is made by cast iron which can take all compressive loads.
It is the main part of the shaper machine. It holds the tool and provides the reciprocating motion to it. It is made by cast iron and mov over ways on column. It is attached by the rocker arm which provide it motion in crank driven machine and if the machine is hydraulic driven it is attached by hydraulic housing.
