Tiller arm machining

Wednesday, June 11th, 2008

Here’s a setup wit three vises for machining model yacht tiller arms. The parts are rotated 90 degrees between the first stage (leftmost) and the second stage (middle), and then again 90 degrees for the final stage (right). There’s some rigid tapping at around 8:20.

Rigid Tapping

Monday, June 2nd, 2008

We’ve mounted a 500 cpr encoder on the spindle-motor which means it’s possible to do rigid tapping. Above some spot-drilling, then a 2.5 mm drill, and then an M3 tap at 500 RPM and 0.5 mm Z-feed per revolution. Below the same thing but with a 5 mm drill and an M6 tap (1 mm Z-feed per rev).

Cool stuff!
