STOCK# 28838
Model No. 50-8 FELLOWS ( Bourn & Koch )”Hydrostroke" 6-Axis “CNC” Gear Shaping Machine
Serial No. 35838 (New 1986, factory rebuild-retrofit/2005)

Suitable for cutting the cutting of internal/external straight spur
gears, splines, and other work-pieces of similar profile up to 50"
(1270mm) diameter, 8” (203.2mm) face-width

EQUIPMENT / FEATURES:

CONTROL FEATURES -
GE-FANUC 16i-M "CNC" Controller, with gear shaping software, color LCD display, and
“user friendly” conversational dialogue program with prompts for easy operator entry/input
of desired cutting parameters. The CNC will control the following motions/axes: - Work table rotation (no change gears required) - Cutter spindle rotation - Work table infeed
- Cutter spindle stroking speed - Stroke position
Both work and cutter spindle have rapid rotation for indicating purposes
Four cut capability selectable via the CNC with stroking speed, depth feed rate,
depth of cut and rotary feed infinitely variable,
with individual parameters preset for each cut as follows:
- Depth of cut - Infeed rate - Stroking speed - Rotational feed rate
- Degree of work rotation
Rotary feed: The custom software on the Fanuc controller allows direct input of rotary feeds for each cut
High output, quick return, infinitely variable stroking drive with adjustable return ratios as follows:
12 to 500 SPM at 2:1 ratio
12 to 300 SPM at 3:1 ratio
Digressive Infeed (infeed per stroke diminishing from a preset high value at beginning of cut to a preset low value at depth)
Re-cut mode allows the operator to bring the part into size without changing the programmed parameters.
Setups can be stored in nonvolatile memory using a setup number between 1-9990

Adjustable cutter positioning at top of stroke
Crowning and taper capability via back off cam
Complete "Hydrostroke" hydraulic power unit
