    Hi nickofen !
    *Everything* depends on your goals ..
    and capacity and productivity depend on rigidity above all else.

    Ex.
    I could cut about 0.1-0.2 mm deep with a typical setup, using a 50 mm wide 4 insert apkt facemill.
    (12" Lathe, upgraded ac servo spindle 2.5 kW continuous.)
    I built a modular vice using 4 pieces of 50x100-300 mm solid tool steel billets, cross-drilled for 16 mm hardened industrial grade 12.8 bolts.
    Vice took 3-4 days to do, and the 4 parts mass == 50 kg.

    I could then cut the same piece, about 200x200x80 mm, with 3.4 mm deep cuts at double the rpm.
    The difference in productivity is about 10:1 - 20:1.

    I don´t think there is a "right" answer, but vastly bigger and heavier and thicker is usually the right choice for *everything* in lathes and mills and routers.

    They deliver about 20x the performance, typically for 100-150€ more in steel costs and 2 days extra work in assembly work and fitup, per assy.

    Vfd an d spindle is here! I have to find time and connect them to test if everything is ok. Is 1.2 mm non shielded wire ok for connecting vfd with spindle?
    For corrosion prevention do I have to use solution of car antifreeze liquid with water? I have read somewhere about a solution of a special anticorrosion oil with water....

    I have a 2.2kw from solar jean I never added anything to the water still coming out clear in the pipes can't see anything in the bottom of the tub I have clear lines which is not good get black ones if possible (Algae).

    I have an ozone pond cleaner which I'll add when I remember lol this will eliminate algae and in the abscence of visible corrosion in the reservoir I'm going to not worry lol.

    I used 1.5mm but reading up 1mm would be fine as well BUT you need it shielded (CY) VFD creates a lot of interference and the most likely thing to cause you issues in the cnc.

    I haven't shielded mine YET and seen no issues but I would not cut anything properly until I have (I only need to connect to earth, it's all in place)

    If you didn't buy it from China the company you bought it from did ;)

    Thanks for the reply Desertboy, I will go for shielded cables then, the cost is not much higher than the non shielded, so it is better to be CY and block all interfierence that I can.

    All modern VFDs use power devices known as IGBTs. These devices make it possible to minimize annoying audible noise by using switching frequencies beyond the audible range. Unfortunately, VFDs using IGBTs, present a high potential for generating RFI - Radio Frequency Interference.

    I've been waiting for 42 days for the T slot nuts to come from China and finally come and with them the frustrating reality!
    Nuts was shorter by .20 and this make them turn and not lock in the aluminium slot!
    I cover the T nuts with self adhesive tape and solve the problem, this took me one day to think it since my nerves was not in good condition,as I was keep thinking that if I make a new order, it will take another 40 days to arrive!

    Good to hear you solved the problem!
    Its frustrating when you get parts that dont follow the specs ;)
