They are used to finish large plane surfaces; the workpiece is held on a movable table which slides in a reciprocating way under a cutting tool., BORING MACHINES, METAL FORMING MACHINES, PLANERS, BAND SAWS, They are similar to planers and are used to smooth plane surfaces. The workpiece is held in a device attached on a table that is driven towards a cutting tool which has a cutting edge on the end of a reciprocating ram., PLANERS, SHAPERS, BAND SAWS, BROACHING MACHINES, They are used to make cylindrical internal surfaces and consist of a bed, a boring saddle, a headstock, a hydraulic device which keeps pressure constant against the piece to be worked., BORING MACHINES, LAPPING MACHINES, GRINDERS, SHAPERS, They are used to finish surfaces, generally hard steel, cast iron, connecting rods, etc., LAPPING MACHINES, BROACHING MACHINES, PLANERS, METAL FORMING MACHINES, They are used to remove material from the workpiece, putting it against an abrasive wheel, which is linked to an electrical motor., METAL FORMING MACHINES, BAND SAWS, BROACHING MACHINES, GRINDERS, They are used to shear, to form, to forge and other operations. Presses, shears and forging machines are all metal forging machines. For example, shears cut sheets of metal which are put on a flat surface using a sharp blade, PLANERS, BORING MACHINES, METAL FORMING MACHINES, GRINDERS, They are used to work many different materials and they consist of a metal toothed blade which moves on two wheels. It is necessary to use a coolant to protect the blade and to use a brush-wheel to remove the material from the blade, BAND SAWS, BROACHING MACHINES, METAL FORMING MACHINES, LAPPING MACHINES, They are used to remove chips from the surface of a workpiece by means of a broach, LAPPING MACHINES, PLANERS, BROACHING MACHINES, BORING MACHINES.
