Abstract: A lubricant nozzle positioning system and method for use with a machine tool having an automated tool changing assembly and a plurality of cutting tools secured therein, for selectively positioning a desired cutting tool to contact a workpiece to be tooled. The lubricating system includes a lubricating assembly having at least one movable nozzle for providing a desired lubricant, and a nozzle positioning subsystem for cooperation with a selected program of the automated tool changing assembly for positioning the nozzle of the lubricating assembly proximate an interface of each cutting tool and a respective portion of a workpiece to be tooled upon sequential movement of the cutting tools into position by the automated tool changing assembly according to the selected program so as to provide the lubricant as desired.

Abstract: A fluid pressure operated cylinder having a removable cylinder head insert or "nose" that carries a replaceable piston rod pressure sealing means and a rod guide bearing. The bearing and seal are mounted around the piston rod bore, adjacent an axially inner end of the nose, and are protected from dirt by a wiping passage that extends to an axially outer end of the nose. The nose is removable from the head for replacement, without disassembly of the head from the cylinder body.
