What Spindle / Auto Tool Changer?

[JAZZCNC]

Honest answer is there isn't any sensible priced ATC spindles available. If your wanting to get away from the Kress and still keep it small then your really really limited on options.
Even if you do happen to find ATC spindle then expect to pay big bucks, minimum £1000 just for cartridge type which still needs motor and inverter/speed control.
There's a guy over on CNC zone trying to do this with BT20 tool holders and think he's got some kick starter scheme thing going trying to do these at sensible money but it's just cartridge type and will still need motor/inverter and will be £1000 + area.!!

Really if you can live with the Kress then possibly best option is to go fro something like this below and for speed control then use something like Super PID. You'll still be in the £1000 minimum area which ever way you go.!!

Sorotec - Tool Changer for Kress

Other than this then expect big money and much larger size spindle.!
