Added photos to the file section of the manufacture of a 100 mm dia 3 jaw self centring chuck that is still
WIP. I have to finish the manufacture of the 3 x pinion gears.
The body is made from aluminium bar, the internal nose and the spiral bevel gear made from phosphor bronze.
All indexing work achieved using a shop built indexer connected by belt to a stepper motor, adopting a
CNC approach with a DDCNC control box and g codes.
I had two approaches to cut the spiral, by either interpolate ending up with a 2000 line g code,, or a simple 6 line g code.
I opted for the second approach.?
A very basic See g code below.as the circular table rotates? 360 degrees, the X mill axis moves 6 mm. IE 2 pitches 12 mm 720 degrees, using a 3 mm dia end mill
2 mm deep.
Hope of interest.
