That woke me up with a jolt!!!  It seems I've got so used to seeing my camera hex perched up on the set of draws in the corner of my bedroom that the area now looks strangely empty without it (I took it apart on Sunday to begin the rebuild into its new Y6 frame)...... And now I'm wide awake at bloody half one in the morning....... And feeling like a paranoid pillock. :(

Aluminium Part Milling?
« on: August 09, 2017, 14:06:19 »
Hi

I need some parts milled from aluminium. I tried to turn them on a mini lathe, but I do not have all year and my ears were not very fond on the screaming. I did debate upgrading my Shapeoko, but I';m really sure what machine would be able to handle up to 50mm aluminium (And I have limited space on where I can keep it). The parts need to be high accuracy as they link a motor and gearbox and I don';t feel like destroying either. Can anyone recommend a place? Or a small footprint machine that would cope.

With Aluminum your best using TiN coated cutters (good quality ones like Titex) and using paraffin as a cutting aid, I';ve turned parts on a home made lathe using a drill and bits of angle.

What is the counter bore depth? And tolerances. Is the position of the 3.3  holes relative to the other holes critical?

I may have an option on a Taig micro mill. This would maybe put me in the realm of being able to machine almost anything I need!

The Taig is quit a nice mill, but limited capacity. Remember  you will need a dividing head to get the hole spaces accurately placed, these take up a lot of table space,and there might not be enough clearance between the workpiece and chuck/collet.

Assembly DRG?

If I get the Taig, it will have a set of Nema 23';s on it pronto! That way I wont need a dividing head.
