Cast Iron PLANO MILLING MACHINE

PLANER MACHINE IS A TYPE OF METALWORKING MACHINE TOOL THAT USES LINEAR RELATIVE MOTION BETWEEN THE WORK PIECE AND A SINGLE-POINT CUTTING TOOL TO MACHINE A LINEAR TOOL PATH. ITS CUT IS ANALOGOUS TO THAT OF A LATHE, EXCEPT THAT IT IS (ARCHETYPALLY) LINEAR INSTEAD OF HELICAL. (ADDING AXES OF MOTION CAN YIELD HELICAL TOOL PATHS) A PLANER IS ANALOGOUS TO A SHAPER, BUT LARGER, AND WITH THE ENTIRE WORK PIECE MOVING ON A TABLE BENEATH THE CUTTER, INSTEAD OF THE CUTTER RIDING A RAM THAT MOVES ABOVE A STATIONARY WORK PIECE. THE TABLE IS MOVED BACK AND FORTH ON THE BED BENEATH THE CUTTING HEAD EITHER BY MECHANICAL MEANS, SUCH AS A RACK AND PINION DRIVE OR A LEAD SCREW.
