The movement of the slide may be controlled either by hand or power to supply crossfeed.The cross-slide is mounted upon the guideways of the saddle and maybe moved parallel to the face of the column.These guideways are perpendicular to the guideways on the base. The top face of the saddle is accurately finished to provide guideways for the cross-slide.The saddle is mounted upon the guideways and may be moved toward or away from the column either power or manual control to supply longitudinal feed to the work.The front vertical face of the column is accurately finished for providing ways in which the ram reciprocates.The column is the vertical member which is cast integrally with the base and houses driving mechanism of the ram and feeding mechanism.The guideways are perpendicular to the column face.The top of the bed is accurately finished to provide guideways on which the saddle is mounted.The base is rigidly built to take up all the cutting forces and the entire load of the machine.The different parts of a slotter machine are, The number of speeds and feeds available, h.p. Amount of cross and longitudinal travel of the table expressed in mm. To specify a slotter correctly the diameter of the table in mm. The size of a general-purpose or precision slotter usually ranges from 80 to 900mm. The size of a slotter machine like that of a shaper is specified by the maximum length of stroke of the ram, expressed in mm. The precision slotter machines are also used for general purpose work and are usually fitted with Whitworth quick return mechanism. Using special jigs, the machine can handle a number of works on a production basis. The length of stroke of a puncher slotter is sufficiently large. The puncher slotter machine is a heavy, rigid machine designed for removal of a large amount of metal from large forgings or castings. There are mainly two types of slotter machine. The slotter machine was developed by Brunel in the year 1800 much earlier than a shaper was invented. For cutting internal or external gears and many other operations which cannot be easily machined in any other machine tool described before.For handling large and awkward workpiece.Used for making regular and irregular surfaces both internal and external.Cutting grooves, keyways and slots of various shapes.Read also: Drilling machine The complete guide The ram can be swivelled not more than 5° to the vertical. The only difference being, in the case of a vertical shaper, the ram holding the tool may also reciprocate at an angle to the horizontal table in addition to the vertical stroke.
