6” Cincinnati Traveling Column, Floor type Horizontal Boring and Milling Machine
Serial # 66-428-R-833-1. Retrofitted in 1995 with DELTA TAU PMAC Operating System with Paradym 3.1 Industrial Control Software.
Foundation drawing: AF-66M-428831

The machine structure is of the “Fixed Work, Traveling Spindle” type.
The Spindle assembly consists of a 6” diameter bar coaxial with a 12” outer Spindle inside a 14” Quill.
The outer Spindle moves WITH the Quill in the “Z” axis. The Bar travels independently of the Quill supported by sleeve bearings, and also moves in the “Z” axis.

X (Cross Travel) Axis travel = 312” (26') (Plus 2” overtravel at each end)
Y (Vertical Travel) Axis travel = 84” (7') (Plus 2” overtravel at each end)
Z Axis travel = 36” (3') (Plus 1” overtravel at each end)

Feed rates:
Manual Mode – X,Y,Z, = 0.5 - 150 I.P.M.
Numerical Control Mode – X,Y,Z, = 0 - 150 I.P.M.
Rapid Mode – X,Y,Z, = 150 I.P.M.

Spindle Speeds: 18 – 1800 R.P.M.
Bar Nose Dia: 6”
Bar Travel (Z Axis): 36”
Intermediate Spindle Dia.: 11.906”
Quill Dia.: 16.500”
Quill Travel (Z Axis): 36”

Ranges:
Intermediate Spindle face to Carrier face: 1.500” – 37.500”
Bar face to Carrier face: 5” – 41”
Bar centerline to top of work table: Max 78”
Bar face (retracted) to edge of work table: Min 7”
