GENERAL DESCRIPTION AND OPERATION
32
Also contained in the valve section are five (5) 1/8” NPT ports for accessory purposes. The ports and their functions are listed as follows:
PORT “A”- provides constant line pressure. This port is used to connect air supply to the
PORT “B”- use for remote start input (page 19).
SPINDLE AND LEAD SCREW SECTION has provisions for pri- mary mounting and houses the spur gear drive train, lead screw shaft, lead screw assembly, main drive spindle and sleeve and a
The spindle is mounted in a precision sleeve by a pair of ball bear- ings and a precision roller bearing.
The spindle sleeve is mounted within two precision finished bronze bushings contained in the spindle housing. The spindle is connected to the lead screw shaft thru a rigid,
PORT “C”is pressurized during the advance and retract cycles
and is not pressurized when the unit is stopped. This port can be - used to control a valve for coolant, cycle completion, etc. (page - 21).
PORT “D” is used to connect port “F”of the | _ |
valve to the retract valve in the valve housing (page 20). | |
PORT “E”- use for remote retract input (page 19). |

spline connection with a final gear of the three spur gear system. Feed is accomplished by connecting the lead screw to the rotating lead screw shaft by means of another rigid,
The
POWER UNIT SECTION is comprised of a reversible motor as- sembly and housing and
mensurate with the planetary gear reduction of a specific model. The planetary gearing is accessible and completely interchange- able for easy change of tapping speed. A typical change of speeds may be accomplished in 15 minutes or less (see page 12).
MOUNTING the unit is accomplished with
keys be used for alignment of the unit to the fixture. Keys (45060)
