Hope you find it useful. Shaper with boring bar Working Principle of the Shaper Machine Working Principle of the Shaper Machine The ram moves at a comparatively slower speed during the forward cutting stroke. It is widely used for key holes, grooves, and cutting slots. Nowadays, Industries try to achieve high The mechanism of hydraulic shaper machine work as a motor that drives a hydraulic pump at a constant speed to deliver oil at a constant pressure to the line. Which of the following mechanism is used in shaper machine (a). The various types of shaping machines: Various types of shaping machines are classified into four such as motion type (driving mechanism), ram travel, table design, and the type of cutting stroke: Types of shaping machine base on driving mechanism: Crank type e.g. There are three types of quick return mechanism. A little consideration will show that the time taken during the right movement of the ram (i.e. In the Shaper machine a single point cutting tool is rigidly mounted on the tool holder, which is mounted on the ram. Shaper Machine Mechanism : 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. In a shaper machine, the mechanism for tool feed is . To get the different velocities of Ram, it is not possible to have different velocities of the crank in two different half revolutions of the crank. Slotter Machine. It is a box like structure which is mounted on the base. The bull gear is a large gear mounted within the column. (or the link DP from the point DP1 to DP2) through an angle α in the clockwise direction, the tool moves from the left-hand end of its stroke to the right-hand end by a distance 2 PD.

In current industrial practice, shapers have been largely superseded by other machine tools (especially of the CNC type), including milling machines, grinding machines, and broaching machines. Required fields are marked *. Abstract:- A shaper is used to machine a single job by using a single point cutting tool and hence it cannot be used for high production rate. Oil present on the right side of the piston is now discharged to the reservoir. Shaper machine works on a single return crank mechanism that provides tool reciprocating motion. In a standard shaper, metal is cut in the forward cutting stroke, while the return stroke goes idle and no metal is cut during this period. In shaping machine, the forward stroke of the tool will be considered as the cutting Stroke in which material removal is taking place from the workpiece and return stroke will be taking as an Idle stroke so that tool is simply moving in backward direction to take the position of the tool.
