In this type of machine, the reciprocating motion of the ram is provided by the hydraulic mechanism. In this machine, the workpiece metal is removed during the return stroke of the Ram. The tool (Single Point) is reciprocating in motion equal to the length of the stroke and the work is clamped in position on an adjustable table. This universal features enables to perform various types of operations on this machine. In this type of machine, you can also swivel the table about its own axis. Either horizontally, vertically or an inclined plane. The major advantages of Universal shaper is that, you can feed the table in all directions. The feed or depth of cut of the tool is given by down feed screw.
The tool head is in the clapper box, which causes cutting action only in a forward stroke of the ram. The Ram reciprocates and it carries the tool head in which single point cutting tool is attached. The vertical movement and Horizontal movement is given to the table by raising or lowering the cross rail using the elevating screw and by moving the saddle using the cross feed screw. It is also mounted on the column on which the saddle is mounted. In heavier type shaper machines, the table clamped with table support to make it more rigid. These surfaces having T-Slots for clamping the work. It is a box-like casting with an accurately machined side and top surfaces. The table can be moved crosswise by rotating the crossfeed rod and also for vertical by rotating the elevating screw. It is also one of the important parts of the machine. It also acts for covering the drive mechanism. Column supports the ram that is moving forward and backward for operation. It absorbs vibration and other forces that occur while performing shaping operations. The base is the most important part of the shaper because it holds all the loads of the machine.
