    Water cooled spindle

    Hello

    I just finished an aluminium extrusion CNC mill project, which I'm currently using with a router Boch colt 1.0 hp.

    Now, I want to limit the noise first, and increase the power of the engine a little with a water colled spindle.

    I'm in a dilemma, I use a standard 110v household with mostly 15 amp breakers. Obviously, I'm looking for a relatively powerful engine that could go up to 0.5" shank. I'm not so knowledgeable in electricity, but I think I could be limited by the type of power I use.

    I would like to know your opinion and suggestions on the subject.

    I'm considering the following two products:

    1) VFD CNC spindle 110v 2.2 Kw er20 collet (1st choice)
    2) VFD CNC spindle 110v 1.5 Kw er11 collet (2nd choice)

    Thank you !

    Jack

    Hi jack,
    I suggest you equip a 110VAC to 220VAC transformer. Because most of the spindles are 220VAC or 380VAC types when their power are over 1KW.

    Hi matey.
    Well in terms of sizes:
    ER11 collets go up to 7mm diameter.
    ER20 collets go up to 13mm diameter.

    You said you want to use 0.5" shank tooling (1/2" I assume your meaning) which is 12.7mm diameter.
    Pretty much answers the question, the ER20.
