Well I too have ordered an OMNI 1325. My main use is cutting Aluminium sheet (0.032 2024 T3), but I intend to cut a fair bit of timber as well.
I did a lot of research before deciding on the specs for my machine, but Jack from Omni has been very helpful through the process. OMNI are very flexible with customising the specs of their machines.
I also had a lot of good feedback from Jason in NZ (http://www.cnczone.com/forums/chines...ordered-2.html)
I only have 220V Single phase so I am going to build the Shopbot vacuum system here -> Black Box Vac Source - Let's Talk ShopBot
I'm looking forward to getting my machine. Will keep the forum up to date with progress. Specs below.
OMNI 1325
1300 X 2500 X 300mm vacuum table (4 zones + combined T slot)
3kw water cooled spindle
2000 X 200 rotary axis
Upgrades:
300mm Z upgrade
30mm HIWIN rails, 32mm TBI ball screw on Z
Helical rack and pinion
Delta VFD
Mach3 Control
Cheers
Richard
