#173B KOEPFER UNIVERSAL HORIZONTAL GEAR HOBBING
New 1982, Serial #173035, Model 173B
- Universal hob head with +/- 90-degree swivel range
range with 140 to 900 rpm spindle speed, and
- Free standing hydraulic unit for tailstock motion,
work-piece clamping cylinder, automatic loading
- Standard index drive (2:45 ratio) for hobbing
- Automatic radial rapid traverse motion. Total
time for rapid approach and return is 1.0 seconds.
- Automatic two cut cycle with 0.2mm, .008", radial
finish cut depth for second cut. Second cut cycle
selectable with the same or opposite feed
- Axial feed rate controlled by change gears.
35 feed rates from 0.1 to 5.0mm/rev., .004 to
- Second cut feed rate selectable in relation to
the first cut by change gears. Ratio of feed rates
- Accelerated feed for approach zone utilizing feed
ratio gears. Note: Additional gear set required,
Item 260. When opposite feed directions are
utilized for two cut cycle accelerated feed is not
- Dwell timer for worm wheels, blind splines, etc.
- Differential for hobbing of helical gears.
- Coolant supply system integrated in machine bed
- Automatic lubrication system with shot lube for
machine ways and recirculation for the gear train.
- Partial machine enclosure with openings necessary
for automatic loading equipment.
- Operator control station for pre-selection of
- Workpiece counter and signal lamp to indicate
required hob shift or change after a pre-determined
- Automatic loading magazine running parallel to
the machine front with provision for inter-
changeable steel strips adjustable to the shape
of different workpieces. This loader is designed
for workpieces that roll by gravity.
- Loader includes transfer unit Type II with one
set of interchangeable transfer centers for moving
the workpiece from the magazine to the machine area
- Unloading system for shafts and small diameter
workpieces consisting of sliding chute. After
unloading the hobbed components are moved
hydraulically to the front side of the machine,
thus avoiding damage. Parts may then be
unloaded at the front of the machine.
- Electrical equipment for operation from 220 or
440 volt, 3 phase, 60 hertz. Note: one supply
- Helical hardened ground change gear set for hob
- Feed rate change gear set for axial feed rates.
- Index change gear set for standard index system
(4:45) and hob heads with 210 to 1680 rpm range.
for hobbing gears with 4 to 60 teeth
- Supplemental change gear set for standard index
system (4:45) and hob heads with 210 to 1680 rpm
range. For hobbing gears with 61 to 120 teeth
- Special index system (8:45) for workpieces with
small numbers of teeth. Min number of teeth to
be cut = 2. In lieu of standard index mechanism
- Equipment for collet clamping fixture
- Hydraulic actuation base for interchangeable tools
such as de-burring disc, steady rest, or automatic
- Hydro-mechanical coping device for crown or taper
hobbing by means of interchangeable templates
- Fixed crowning template for one workpiece
- Coolant drip container in large execution for
- Additional coolant piping for lubrication and
cleaning of the clamping system work area, etc.
- Full machine documentation, operator's manuals,
parts list, hydraulic and electrical diagrams
