(diameter ???)
Full complement of electrics (motors/controls)
* presently arranged for 480 volt, 60hz operation ???
Siemens sinumerik "system-3" continuous path "cnc"
control for linear motions w/incremental measuring
systems,digital position read-outs and integrated
programmable control for axial, radial, and
tangential motions, hob-head swivel within work
cycles, helix angle, hob and table revolutions.
Siemens axis drive and spindle drive with siemens and
heldt & rossi table index, with sychronization of
hob and table rotation via pfauter "geartronics"
electronic-gear-box.

( CNC-CONTROLLED CYCLES / FUNCTIONS / FEATURES )
- Feeds per workpiece revolution
- Axial hobbing, radial & axial hobbing
- Hob shifting and precision hob shifting
- Multi-cut cycle w/feed & speed change
- Crown hobbing with maximum contour radius of
99.99mm (via circular interpolation)
- Taper hobbing with desired angle (via linear
interpolation)
Cnc controlled cycles provide various combinations
of the above, including two-cut-work cycles with
speed and feed change between cuts,
dwell-at-cycle-end,as well as other axiliary
functions
Operator's dialogue program in either mm or inch,
with data entry prompts via the cnc for number
of teeth in work-piece, helix angle, number of
hob-starts, etc.
Direct programming of hob speeds via the cnc
Smallest programmable increment (0.001mm)
