Thread: My second router design

Hello
I have now started work on my second CNC machine! these things are very addictive!
I have drawn up some plans on Google sketch up and thought I would post them here to see what other people thought of the designs and to see if there was any problems that I haven't spotted as my last machine has many 'faults' should we say.
The basic features are:
a working envelope of 700 x 550 x 200
it uses SBR20 supported rail throughout along with RM1605 ball screws all purchased from chai in china as I am there now so I can cut down shipping cost
the spindle is a 2.2kw water cooled model that I already have from my other machine
The main construction material is eco cast aluminum tooling plate which is machined flat on both sides and the main gantry and black piece is 20mm thick
all the parts are to be cut out on a CNC mill, hopefully the proto track at my university so this should ensure that all parts are square and this should mean that on assembly the machine is more acurate
I have not decided on motors and drivers yet but I am thinking the high voltage kit that is supplied from Zapp which uses 3nm motors and 60V+, it would be good to see what people think about this.
the main aim of this machine is to be able to cut wood, plastic and aluminum, my hope is to be able to cut aluminium at a reasonable speed for a DIY machine but I am not sure if the machine will be rigid enough.
any constrictive criticism is welcome, and I look forward to hearing what you think about my design. I may have not put enough info about the design so any questions just ask
Joe
