SLOTTING MACHINES The slotting machines are machines with chip removal, suitable for creating, on pieces of steel, grooves, cuts, taps, Woodruff keys, tabs also for planing internal surfaces of a hole. The machine operation is similar to that of the shaping machine, but the toolholder slide works with rectilinear reciprocating motion vertically instead of horizontally, and with a shorter stroke. The slide can also be tilted. The feed is given to the piece fixed on the workpiece table, and can be longitudinal, transverse or circular. The mode of chip removal are similar to those of the shaper and planer.
