So i have posted before regarding the use of "Sandvik Capto" tooling in various situations. Thought some might enjoy seeing an example of boring work having a long reach.
Machine is Deckel FP4NC. Early "Camel Back" vertical head setup. Machine is set to run horizontal. Largely because the part calls out to be run that way , but also because i believe that the
machine is most stable and rigid working horizontal....
Here is the job requirement:
Semi finished casting. Fits as the gearbox cover on a Type35 GP Bugatti. The cover is made with an extension that cradles the starter motor.
Starter has a round body. !00 mm that needs to seat on that extension.
Seat ares must be machined to match the starter body and at the correct height to set the starter pinion relative to the engine flywheel and ring gear....
Overall view of the setup:
Cover gasket face clamped to 2-4-6 blocks on machine table. Jacks and additional clamps to secure the extension of the casting.
Overall reach of "Capto" setup including quill extension: 428mm (16.85")
Surface of the starter seat easily seen here...
Opposite side view.....
End tool is single point "precision " boring head. Has removable cartridges that can carry different styles of insert tools.
This job i am running an 80* "CCGX style positive insert graded (un-coated) for aluminum....
Size of the cutter was set using a stand alone tool setter "Walter" that has optical/DRO gauging for both the diameter and length .....
More to follow.
Cheers Ross
